NORMAL TRAILER OPERATION

This Timpte trailer is designed for operation within legal highway speed limit s on reasonable road
surfaces for the type of service it was built to perform, in accordance with the noted weight restric­tions.

“Normal Service” means the loading and transportation of uniformly distributed legal loads of
properly secured, noncorrosive cargo, in accordance with any applicable factory instructions and
in a manner which does not subject the trailer or parts of the trailer to (a) concentrated loads; (b)
loads in excess of the Gross Axle W eight Rating (GAWR) or Gross V ehicle Weight Rating
(GVWR) stated on the Certification Plate affixed to the trailer by T impte; and (c) accidental dam­age, or (d) stresses, impacts or shocks greater than those commensurate with normal, reason­able lawful use.

The GAWR (gross axle weight rating) is the structural capability of the lowest rated member of the
running gear components: suspension system, hubs, brake drums, wheels, bearings, axles, brake
linings or tires.

The GVWR (gross vehicle weight rating) is the structural capability of the trailer when supported by
the kingpin and axles with the load uniformly distributed throughout the cargo space.

NOTICE:

The maximum load indicated on the identification plate

may not be a legal load on the highway you plan to use.

States have differing laws and regulations affecting vehicle

lengths and weights on roads that are not a part of the

primary interstate road system.

Modification of the Trailer – Any modification made to the trailer must comply with DOT and
NHTSA regulations and must not compromise the gross vehicle weight rating (GVWR) of the
trailer. Any modification made to the trailer without prior approval of T impte may void the warranty .
Any operation of the trailer outside the limitations stated in this manual will void any responsibility
of Timpte Trailer Company for any of its result s.

AIR BRAKE SYSTEM

Your new Timpte trailer is equipped with an air brake system which meet s or exceeds the require­ments of the federal regulation FMVSS-121 for grade-holding ability and emergency stopping in
the event of an air supply failure in the service brake system. Air pressure is required to release
the parking/emergency brake. As of 10/8/92-FMVSS 121 requires that the supply line for the air
brake system be protected to 70 psi. This pressure level requires that supply line pressure levels
are achieved before the pressure protection valve opens (opening pressure must be higher than
the closing pressure by design).

Keeping your compressor cut-in pressure at maximum levels (over 100 psi) is a clear advantage
for peak operation of your entire system, we recommend using a 105 psi cut-in governor setting.
Governor cut-out pressure should be at 120 psi minimum. Low compressor cut-in pressure may
result in poor performance of the system, for example slow parking brake release time.

Should you still have a problem with your brake system after working through all of the inspection
items and tests listed in this manual’s maintenance section or in the brake manufacturer’s manual
supplied with the trailer , contact your T impte factory representative.

WHEEL NUT TORQUE

Proper torquing and retorquing the wheel nuts are critical to prevent the loss of wheel equipment.
Wheel nuts should be torqued to 450 to 500 ft. lbs. (dry). Refer to the manufacturer’s decal on the
side of the trailer or manufacturer’s maintenance information supplied with the trailer for proper
torque specifications and tightening sequence.

Wheels must be checked and retorqued after the first 50 to 100 miles of use. This is important
every time you change a wheel. Check the fastener torque on a regular on-going basis.

!

WARNING

1. Read and understand this warning and the installation, Service and Safety Instruction Manual to understand
all safety precautions, proper operation, and maintenance of your Webb hub. Failure to do so could result in
death or serious injury and could result in a compromise of your vehicle’s safe operation through loss or failure
of a wheel or the compromise of the braking system. Copies of the installation, Service and Safety Instruction
Manual are available, free of charge, from Webb Products, Inc., upon request.

2. Always use a properly installed calibrated torque wrench to assure proper torque. Under torque and over
torque can cause thread and/or nut damage and could result in the loss of a wheel. Failure to ensure proper
torque could result in death or serious injury and could shorten the expected life of this product.

3. Recheck torque after the first 50 to 100 miles of service. Parts may seat naturally, causing the torque to drop.
A drop in torque could result in the loss of a wheel. Proper torque is essential to avoid damage or compromise
of your vehicles safety. Failure to ensure proper torque could result in death or serious injury.

REAR IMP ACT GUARDS

As of 1/26/98, all trailers must comply with FMVSS 223 and 224, which specify equipment and
performance standards for rear impact guards on new semi-trailers. If required by this statute, a
RIG (rear impact guard) has been installed on your trailer that has been designed to resist speci­fied forces and absorb energy at a specific rate in the event of a rear collision with the trailer per
the standard. T railer RIG’s are subject to impacts and stress in docking and loading operations.
It is therefore important that you inspect them regularly for signs of damage or wear . Failure to

follow this warning could result in serious injury or death.

!

A DAMAGED REAR IMPACT GUARD MAY NOT BE AS STR ONG AS THE ORIGI­NALLY MANUFACTURED GUARD AND MAY NOT SATISFY THE PERFORMANCE
STANDARDS OF FMVSS 223 AND 224. ALTERATIONS OR REPAIRS TO THE RIG
COULD HA VE THE SAME EFFECT. PRIOR TO REPAIRING OR MODIFYING ANY
TIMPTE RIG, CONTACT THE VICE PRESIDENT OF ENGINEERING AT TIMPTE AT

402-367-3056. FAILURE TO FOLLOW THIS WARNING COULD RESULT

WARNING

IN SERIOUS INJURY OR DEATH.

Pre-trip inspections should be made of the guard to assure its integrity and strength. Broken
welds, bent components, or other damage will likely affect its performance.

For these reasons, RIG inspection, service and repair records should be maintained. Repairs
and replacements must be in accordance with the original design specifications of the guard. Any
questions regarding repair or replacement should be directed to the Vice President of Engineer­ing at Timpte.

ABS BRAKING SYSTEM

As of 3/1/98 all trailers manufactured with air braking systems are required to have an ABS (Anti­Lock Braking System).

The system used on your trailer meets or exceeds the FMVSS 121 requirement for ABS. The
ABS system on your Bulk Commodity trailer is a 4S/2M system (4 wheel sensors - 2 modulator
valves) or a 2S/1M (2 wheel sensors - 1 modulator valve). The intended purpose of ABS is to help
maintain control and reduce the likelihood of jackknife situations.

The ABS st atus indicator light is located on the driver side of the trailer near the rear corner post.
It indicates the system status upon initial startup by turning on and then turning off once the vehicle
begins to move. If a malfunction in the ABS system occurs, the ABS system st atus light will come
on and stay on until the problem is repaired. Anytime the system st atus light comes on and stays
on, have the ABS system serviced as soon as possible.

WARNING! ABS (Anti-Lock Braking System) is a safety item and must be

properly maintained. To operate an ABS equipped truck and trailer properly,

!

BACKUP WARNING SYSTEM

A backup warning system consisting of an audible alarm is available as an option on your Timpte
Bulk Commodity trailer . The system is intended to indicate that the vehicle is backing up.

during braking- constant pedal force must be applied. All ABS systems require
clean, dry air to operate properly. Use of airline deicers or leakage of oil into the
air system may diminish the performance of the system and will void the warranty.

Date of Origin – 02/01/08

You, the operator, have the Greatest Control

over Safe Operation.

1. You, the operator, have control of the most import ant factors that affect safe trailer opera­tion and vehicle stability . T railers are a tool and, like any tool, are safe only when properly
used by a conscientious, trained and qualified operator.

2. The fifth wheel should be securely mounted to the tractor frame and proper connection
between the tractor and trailer verified.

3. The driver should be familiar with the characteristics of the particular trailer and of the
load to be transported.

4. The driver should be familiar with the nature of the roads and traffic which may be en­countered during the trip.

5. Stability – Caution - like any other vehicle, semi-trailers can tip or slide out of

control if turns are negotiated at too high a speed or when making violent ma­neuvers such as abrupt lane changes or other evasive actions to avoid ob­stacles.

6. Within the relatively narrow confines of road laws limiting vehicle size and weight, to­gether with the characteristics of available tires, suspensions, and other components,
there is little that a manufacturer can do to affect the inherent stability of a trailer other
than keeping the load as low as feasible, considering the requirements for loading space
and adequate tire clearance. This means that the major factors affecting operational
stability are the knowledge and skill of the driver . The predominant causes of rollover
accidents are:

a. Excessive speed
b. Violent swerving or turning
c. Application of brakes or tractor power while turning.
d. Entering curves at too high a speed

7. Tire Characteristics: High pressure truck/trailer tires have different characteristics under
high speed cornering conditions than do passenger car tires. Truck/trailer tires are
designed for carrying high loads over long distances. Their lateral stability becomes
unpredictable when lateral forces approach .04g. This means that commercial vehicles
must be operated in a conservative manner when cornering.

8. Braking and Acceleration: Either braking or accelerating while cornering can significantly
reduce the stability of the vehicle and should be avoided. The best driving practice is to
decelerate to a safe conservative speed before entering a corner or approaching con­gested traffic, and then to apply only moderate power until a straight path has been re­established.

Inspection Procedures Before Each Trip

WARNING! Be careful when making inspections, hookups and rep airs to

!

avoid personal injury . Make sure p arking brakes are properly activated or that
wheel chocks are in place to avoid sudden or unexpected movement of the
trailer which could result in bodily injury .

NOTICE:

It is the Operator’s responsibility to conduct a safe and accurate pre-trip
inspection of the vehicle. Per Federal Motor Carrier Statute 49 CFR 392.7
Equipment, Inspection and Use - No motor vehicle shall be driven un­less the driver thereof shall have satisfied himself that the following parts
and accessories are in good working order, nor shall any driver fail to
use or make use of such parts and accessories when and as needed

Service Brake, including trailer brake connections
Parking Brake
Steering Mechanism
Lighting devices and reflectors
Tires/Tire Pressure
Horn
Windshield Wiper or wipers
Rear-vision mirror or mirrors
Coupling devices
Hoses and Airlines
Fifth Wheel Plate
Gladhand Connections
Hub Maintenance
Mud Flaps
RIG (Rear Underride Guard)

Additional Federal Requirements for the Operator can be found in the Federal Motor Carrier Safety
Regulations (FMCSR’s) in the Code of Federal Regulations (CFR) Title 49 Parts 392, 393 and 396.
These can be found on-line at http://www.access.gpo.gov/nara/ then scroll down to (CFR Sections by
Citation).

Failure to regularly inspect the trailer may also void the warranty .
While it is ultimately the operator’s responsibility to properly perform and document the pre-trip

inspection, Timpte provides the following recommendations and suggestions.

TRAP DOOR LOCKS

Check all trap door locks before each trip to insure that they are in proper working order . Any trap
door components which show excessive wear should be replaced immediately. Care should be
taken to keep the area around the door frame clear of any debris. A build-up of refuse may result
in the doors not completely closing.

Make sure all doors are closed and secured prior to departure.

Date of Origin – 02/01/08

LIGHTS AND REFLECTORS

The surfaces of the lights and reflectors need to be checked and cleaned. Inspect all lights to
see if they are working and check all brake and signal functions.

ELECTRICAL WIRING

Inspect all visible wiring to see that it is not frayed and is properly supported and protected, and
that all connections are tight. Inspect the electrical hookup for a clean and secure connection.

FIFTH WHEEL AND KING PIN ENGAGEMENT

Inspect the kingpin and its structure on the trailer for damage or unusual wear . After hook up,
make a direct visual inspection to assure proper coupling, then check for positive engagement of
the lower fifth wheel and king pin. Apply the trailer brakes and attempt to move the tractor forward
to insure that the fifth wheel and king pin are positively locked.

CAUTION! Plastic King Pin Liners (Lube Plate) cannot be installed onto Timpte Trailer

!

TIRES

upper coupler/king pin assemblies unless the trailer was purchased with that specifi­cation. A lube plate changes the king pin interface dimensions relative to the fifth
wheel lock. This may result in coupling difficulties, premature lock wear , and a poten­tial for a dropped trailer.

WARNING! DO NOT OVERLOAD! Check tires frequently for cuts and abrasions.
Check tire pressure daily and keep inflated as recommended by the tire manufacturer.

!

MUD FLAPS

Be sure the mud flaps are securely in place and in good condition.

TARP SYSTEM

Check to be sure the tarp is in serviceable condition. Insure that the latching system is in good
working order and that the tarp is properly secured for travel to prevent being blown about by the
wind.

LANDING GEAR

Always raise the landing gear legs completely before moving the trailer. Make sure that the crank
handle is properly secured. Prior to trailer transport, lock landing legs into low side gear ratio.

Remove foreign objects that may be lodged in the tire treads or between dual tires.

Date of Origin – 02/01/08

HUB MAINTENANCE

Check wheel studs for good condition – no stripped threads – no bent or loose studs. Replace
any broken or bent studs or studs with damaged threads. When a broken stud is replaced, the
stud on each side of it should be replaced at the same time. If more than two studs on the same
hub are broken, replace all of the studs. NOTE: Hub cap mounting bolts (6) torque 10 to 15 ft. -lbs
torque per bolt.

WHEELS AND RIMS

Check all wheel nuts for tightness. Wheel flange nuts should be torqued to 450 to 500 ft. lbs (dry).
Check all metal surfaces thoroughly while making tire inspections and during tire changes.

Look for:

• Excessive rust or corrosion build-up

• Cracks in the metal

• Bent flanges or components

• Loose, missing, or damaged nuts

• Bent or stripped studs.

• Incorrectly matched rim parts

Replace damaged components, making sure that replacements are made with proper sized and
type parts.

!

EXCESSIVEL Y CORRODED OR CRACKED RIMS ARE DANGEROUS, PARTICU­LARLY DURING REMOVAL. DEFLA TE TIRES PRIOR TO REMOVAL OF RIMS AND
WHEELS FROM THE VEHICLE OR PERSONAL INJURY COULD RESULT .

HUB LUBRICANT

Check and maintain proper level of lubricant in hubs.
Hubs using oil lubricant will have clear hub windows and the oil level will be clearly visible. Be sure

the oil level is at the fill line noted on the hub window .
Hubs equipped with synthetic grease will retain the grease between the bearings and no lubricant

visual check is possible. Trailers equipped with this option will not have a clear hub window or a
fill plug.

Do not add oil to hubs equipped with synthetic grease lubricant. If mixing of lubricants occurs,
remove the lubricant and re-install the proper lubricant as soon as possible.

TRAP DOOR OPERATION

Single Speed Trap Openers (Ratchet and Pawl)

• Couple the socket end of the crank handle completely and securely over the hex drive nut on

the trap operator shaft.

• On the front tub, rotate the crank handle slightly clockwise, this will release the pressure on the

ratchet pawl and allow you to rotate it out of the ratchet gear .

• Once the pressure on the pawl is released, rotate the pawl counterclockwise until it comes

to rest on the other side of the ratchet gear .

• Rotate the crank handle counterclockwise to open the trap door. The crank handle swings in a

large arc so be sure the area is clear.

• The door can be stopped at any point in the travel and the pawl will hold it from opening further.

• If you determine that you have opened the door too far and need to partly close the door to

meter the speed of the discharge, release and rotate the pawl back clockwise before rotating
the crank handle clockwise to close the door .

• Rear trap door operates opposite of front trap door.

2 Speed Operators (Gear Reductions)

• Choose gear box mode you want to operate; direct drive or gear reduction. Drive nut
assembly without locking latch is the gear reduction side.

• Raise the locking latch to free the operator .

• Couple the socket end of the crank handle completely and securely over the hex drive nut on
the trap operator shaft.

• Rotate crank arm clockwise or counterclockwise to open trap door per instruction decal
(direction of rotation is dependent upon mode chosen). The crank handle swings in a large arc
so be sure the area is clear .

• Rotate crank arm opposite direction to close the trap door.

• Lower locking latch to lock the operator .

• Rear trap door operates opposite of front trap door.

TRAP DOOR LATCH (PAWL) - Setup and Adjustment

• Use the trap door operator shaft to close the trap door.

• Locate a torque wrench onto the hex drive nut on the operator shaft.

• Rotate the wrench to close the trap door until the door is completely closed (decals).

• Locate the pawl lock to a position approximately 1/2 tooth away from the next gear ratchet
wheel locking position (pictured).

• Rotate the torque wrench in the ‘close’ direction, torque wrench set point at 80 ft-lbs
(max), until pawl drops into gear ratchet wheel tooth to lock door closed. Pawl lock must be
set to drop into the gear ratchet wheel lock at a torque < or = 80 ft-lbs latching torque.

• Adjust pawl position side to side to fine-tune pawl latching torque set point.

• Release the door lock by rotating the operator shaft toward the ‘close’ direction, easing the

locking pressure on the pawl. Raise the pawl lock out of the ratchet wheel tooth and rotate the
pawl in the opposite direction. Open the trap door by rotating the operator shaft, with the crank
arm, opposite the ‘close’ direction (decals). Unlatching torque should not exceed 80 ft-lbs
torque.

Date of Origin – 02/01/08

16

NOTE

• The pawl lock should be centered on the gear ratchet, front to back, to assure proper
alignment between ratchet and pawl for locking.

• Use set screws, located in flange bearing (behind operator shaft mounting plate), to adjust
clearance for pawl and gear ratchet centering. (See figures below for clarification).

• Adjust the pawl and ratchet centering position as follows:

• Loosen adjustment set screws (2) to allow operator shaft/mounting plate
movement (in and out, push/pull).

• Confirm clearance between gear ratchet and mounting plate (push/pull)

• Adjust gear ratchet and pawl for centering (in and out movement, push/pull).

• Re-tighten set screws on flange bearing once centering and clearance are corrected.
DO NOT over-tighten set screws to avoid damage to operator shafts.

EASY FLOW HYDRAULIC DOOR TROUBLE SHOOTING GUIDELINES

21

Date of Origin – 02/01/08

PRESSURE RELIEF ADJUSTMENT

The hydraulic power supply pump is equipped with two pressure relief valves to maximum system
pressure at a safe level. These relief valves are located on each side of the pump, 180 degrees
from each other. At the hose connections the ports on side of the pump are marked with “C1” and
“C2”. The pressure relief on the “C1” side sets the pressure for opening the doors and the relief on
the”C2” side sets the pressure for closing.

When testing or making adjustments on the pressure relief valve system a gauge in both ports of
thepump is required to ensure the most accurate pressure setting. To adjust pressure relief valves:

Setting Relief Valves with Pressure Gauges:

1.Insert pressure gauges in each pump port “C1” and “C2”.

2.A Pressure Relief valve is located on each side of the pump. Use 9/16” socket and loosen the

jamnut on each relief. Do not remove relief valve.

3.Use a 3/16” hex head wrench and turn the relief clockwise to increase pressure setting, counter

clockwise to reduce the pressure. Approximately ¼ turn or 90 degrees equals 250 psi
adjustments.

4.Operate the system until the cylinder is “dead headed” (cylinder at full stroke or fully retracted)

and note the pressure on the gauge. Pumps from factory are preset at 2000 psi.

5.Cycle cylinders in both directions until pressure setting are achieved on both reliefs.

6.Tighten jam nuts and remove gauges.

7.Cycle system to remove any air that may have entered the lines when the gauges were removed.

Setting Reliefs Without Gauges:

1.A Pressure Relief valve is located on each side of the pump. Use 9/16” socket and loosen

the jam nut on each relief. Do not remove relief valve.

2.Use a 3/16” hex head wrench and turn the relief clockwise to carefully bottom out relief valve.

Do not tighten. Tightening relief valve can damage the valve seat.

3.Turn relief valve counter clockwise 1 revolutions. Tighten jam nut s. This will set the pressure at

approximately 2000 psi range. Approximately ¼ turn or 90 degrees equals 250 psi adjustment.

Date of Origin – 02/01/08

EMERGENCY APPLICATION WITH DRILL

1. Remove Plug from rear of hydraulic power unit motor using a 3/16” Allen wrench.

2. Insert 6-mm hex head wrench attached to an electric drill into opening of motor. Make sure hex
key is properly seated into motor before operating drill.

ROLL TARP

• The tarp must be kept to a recommended 40-60 lbs.

ATTENTION!

of tension or excessive tarp wear may occur.

• Do not walk or stand on the end caps.

• Do not operate this vehicle at highway speeds, while
the tarp system is in the “open” position.

OPERATING INSTRUCTIONS

1. Crank The Tarp Up
Under The Latch Plate.

2. Bring The Crank Arm
Down To A Vertical
Position.

A decal located on the rear of the trailer gives instructions for the operation of the tarp and adjust­ing the tarp tension. A caution decal is located on the crank handle with instructions pert aining to
rolling the tarp. Be sure to follow these instructions.

3. Lift The Crank Arm Up
To The Crank Retainer.

T o Adjust The Tarp Tension:

1. Allow The Tarp T o Roll
Down Away From The
Latch Plate.

2. Remove The Crank Arm
From The Splined Shaft.

3. Rotate The Crank One Or
Two Teeth & Reassemble.

IMPORTANT: All tarp bows and cross members must be in place while operating a

loaded trailer . The tarp bows and cross members hold the trailer walls together and prevent side

structure failure. Always close tarp and lock handle into position before moving your trailer to
prevent damage to the tarp system.

Always open the tarp before discharging a load. Failure to do so may damage the trailer and void
the warranty .

If you must remove or reposition the ridge straps or tarp bows during loading, be sure to use a
safe, approved walkway or scaffold. Never walk on the top rail, it is not designed to be a walkway .

TARP TENSION

To Set the Tarp Tension On The Crank:
METHOD ONE:

Hold the crank firmly with both hands
Tighten the tarp by rolling the main t arp tube up under the latch plate
Bring the crank handle down perpendicular to the ground
Continue to tighten by lifting it up (approximately 45 degrees) into the crank retainer:
Repeat this procedure while adjusting the splined shaft and the u•]joint one tooth at a time to
achieve 40 to 60 pounds of tension at the handle end of the crank.

Date of Origin – 02/01/08

24

METHOD TWO:

Another method to measure tension is to adjust the tension until you see a slight deflection or a
gradual bend in the crank extension of approximately 1/8”.
After Properly setting the tension on the crank, make sure that the tarp is in the locked position
and check the following:

Check to see that the tarp has equal tension on both the end caps and the bows.
If, for any reason the tarp tension is not the same along the length of the tarp (i.e. tarp twist,
uclamps not aligned, varying box widths from front to back), the u-clamps and the tarp may
need to be readjusted in the loose areas of the tarp.

WARNING! DO NOT walk, stand or climb over or on the end caps. The tarp

caps are designed by the tarp system manufacturer to assist in supporting,

!

tensioning and sealing the tarp. They are not a structural portion of the trailer .
They are purposely light-weight and flexible and are not designed to support a
person’s body weight. Additionally, they are purposely smooth and curved to
assist the tarp in sealing tight, and hence are not designed to be a walk surface.
Failure to follow this warning could result in serious injury or death.

THUNDER ELECTRIC T ARP SYSTEM

OPERATING INSTRUCTIONS - Powering Up or Down the System

To turn the system on or off, locate the “OPEN” and “CLOSE” buttons on the relay module on the
front of the trailer. Push and hold both buttons simult aneously for approximately 3 – 5 seconds.
The red LED will illuminate indicating the module is on and ready for opera¬tion. Alternatively, you
can also press and hold buttons “ON/OPEN” and “OFF/CLOSE” on the RF transmitter for 3 – 5
seconds to power the system on or off.

One Touch Operation:

This operation is fully automated and will stop when proper tension is reached when fully opened
or closed.

To uncover the load, push and hold the button labeled “OPEN” on the relay module or “ON/OPEN”
on the RF transmitter for 1 to 2 1/2 seconds then release. The gear motor will wrap the tarp
around the tarp axle causing the axle to move from the tarped position to the stowed position.
This tarp system can be opened part way and stopped. Anytime you want to stop the t arp system
just hit the “OPEN” or “CLOSE” buttons or “ON/OPEN” or “OFF/CLOSE” on the RF transmitter
and the tarp system will stop. It will not hurt the tarp system to stop part way through the tarping
cycle. When the system shuts down automatically , the system will be set to the recommended t arp
tension. Never travel with the tarp in a partially covered position. The trailer should always be
covered when traveling.

To cover the load, push and hold the “CLOSE” button on the relay module or “OFF/CLOSE” on the
RF transmitter for 1 to 2 1/2 seconds. The springs in the arm will move the tarp from the stowed
position and across the trailer to the tarped position. When the system shuts down automatically,
the system will be set to the recommended tarp tension.

Incremental Operation:

To inch the tarp in either direction press the “OPEN” or “CLOSE” buttons on the relay module
intermittently.

Press and Hold Operation:

To uncover the load using the press and hold feature, push and hold the button labeled “OPEN” on
the relay module or “ON/OPEN” on the RF transmitter . The gear motor will wrap the tarp around
the tarp axle causing the axle to move from the tarped position to the stowed position. Release
the button when the system shuts down automatically . This t arp system can be opened part way
and stopped. Anytime you release the switch the tarp system will stop. It will not hurt the tarp
system to stop part way through the tarping cycle.

Never travel with the tarp in a partially covered position. The trailer should always be covered
when traveling.

To cover the load using the press and hold feature, push and hold the “CLOSE” button on the relay

module or “OFF/CLOSE” on the RF transmitter for greater than 2 ½ seconds. The springs in the
arm will move the tarp from the stowed position and across the trailer to the tarped position.
Release the switch when desired during operation or when the system shuts down automatically .

Date of Origin – 02/01/08

26

OPTIONAL ARM ADJUSTMENT

As shipped from the factory , the front and rear arms are set to allow the axle to rest lightly on the
end caps while following the contour as it moves across the trailer .

Different types of loads and conditions may require your tarp to operate differently. For this rea­son the system has been designed to be very versatile. Please see the steps below to adjust your
arm if need be.

To make the arms carry the axle over heaped loads: Increase the knuckle pressure on the front
and rear arms by moving the spring pin up to the middle hole. If even more lift is desired, move
the spring pin to the top hole.

To increase arm control in windy conditions:

Increase the base pivot pressure on the front and rear arms by moving the spring pin up to the
middle hole. If even more control is desired, move the spring pin to the top hole.

Recommended Maintenance:

All electrical connections should be checked regularly for corrosion. If any con¬nections are found
with corrosion, clean the connection and apply dielectric grease before reconnecting. Electrical
connections can be found at all motors, switches, contactors, limit switches, control boxes and
batteries. Motor mounting bolts should be checked periodically to ensure a minimum torque of 70
in-lbs (5.8 ft-lbs). All mounting hardware should be checked to insure all system components are
securely fastened. Visually inspect all moving parts for abnormal or excessive wear.

Field Troubleshooting Guide:

1. Check main circuit breaker at battery to make sure it is not tripped. If tripped, reset.

2. Check all connections to make sure they are properly secured both at the termi¬nal connec­tion to the stud and where the terminal is crimped to the wire. Loca¬tions to check: battery
connection, circuit breaker near battery , male and female plugs, relay connections, motor
connection.

3. Ensure relay is powered up. If the RF module is on, the LED will be solid red. If the LED is
not on, power the module up by pushing both large buttons simultaneously for 3 – 5 seconds
until LED turns on. If RF module will not power up, remove and replace. If module will power
up but system will not function, proceed to step 2.

4. Disconnect power leads from motor. Check for motor operation in both directions. To do so,
use a set of jumper cables to go direct from battery to motor terminals (+lead to + terminal, ­lead to - terminal). To reverse direction, remove the jumper cables from terminals and swap
the leads to the opposite terminals (+lead to - terminal, - lead to + terminal). If motor does
not operate in one or both directions, replace motor. If motor operates in both directions,
proceed to step 5.

5. Reconnect input wires to motor and check for operation.

6. Using a voltmeter or test light, check for input power at relay . If using voltmeter , input voltage
should be a minimum of 12V. If voltage is good, proceed to step 6. If no or low voltage,
proceed to step 7.

7. Check voltage at relay output. To do so, connect tester leads to output terminals. Activate in
one direction, check voltage, activate in opposite direction, and confirm voltage. If no or low
voltage, relay must be replaced. If good proceed to step 8.

8. Check voltage at output circuit breaker located near battery . If no or low volt age, replace

circuit breaker.

LIFTABLE, REGULA TED AXLE

For trailers equipped with a Liftable, Regulated axle, the air controls are on the roadside near the
suspension of your trailer. This box contains a 160 p.s.i. regulator along with a locking detent lif t
control valve, and a manually adjustable regulator knob. The regulator is adjusted manually to
control the pressure of the lift axle ride bags.

T o control the load on your lif t axle, with the trailer loaded, pull the regulator knob and turn to the
desired pressure. This can be accomplished by placing the lift axle on a scale while the adjust­ment is taking place. Once the desired load is on the axle, push in the knob to lock the adjustment
in place.

lift or lower the axle, rotate the locking detent lift control on the valve counterclockwise Y4 turn to

To
a horizontal position to lift and then back clockwise Y4 turn to a vertical position to lower the axle.
The lift axle is considered a ‘pushing axle’ and it is very important to always lift the axle when the
trailer is empty and lower the axle when
the trailer is loaded.

If the axle were to be connected to electrical power, the lift has a personal safety feature that will
allow the axle to lift when the power is disrupted.

NOTE: Loading the axle should never exceed the wheel, tire, or axle rating.

GENERAL MAINTENANCE

AVOIDING CONT AMINATION

The operator has the best opportunity to avoid contamination between commodities. It is critical
that the operator clean and maintain the trailer interior and trap frame areas to avoid contamina­tion. The interior hopper, dividers, etc. should be inspected and cleaned thoroughly by the opera­tor as required. Use a broom or a high pressure sprayer to clean the interior surfaces including the
dividers, wall liners and interior tub panels. Do not use a high pressure sprayer for trap frame
cleaning and washing. High pressure water could enter and damage the bearings. Access to the
interior of the trailer should be from underneath through the trap door opening. Never climb over
the top of the trailer into the interior . See section below for trap frame maintenance.

TRAILER WASHING

Washing the trailer is an important step in decreasing future maintenance. The trailer should be
washed with soap and water using a relatively soft bristle brush. V arious chemicals can cause
severe corrosive damage to aluminum. The use of acid in any concentration to clean the trailer
will void the warranty .

There are many different types of chemicals used today to de-ice the roadways. Many of these
can cause severe damage to the steel substructure of the trailer and diminish the appearance of
the aluminum and stainless steel components if not kept properly and regularly washed away .

A number of products hauled in the trailer will also lead to corrosion if the products are allowed to
build up. Products that build up on the aluminum and steel members in the suspension subframe
and upper coupler area should be routinely washed off.

CORROSIVE DETERIORA TION

V arious chemicals can cause severe corrosive damage to your aluminum grain trailer. T o prevent
severe damage to your trailer due to corrosion, contact T impte Trailer Company Product Engi­neering to verify that the materials you are hauling are compatible with the materials used in the
construction of the trailer.

Corrosive deterioration caused by incompatible materials could void all or part of the
trailer warranty .

The most important preventive maintenance step to avoid corrosion is cleaning; your trailer should
be washed out after each load to minimize corrosion when hauling such items as salt, fertilizer ,
etc.

TRAP FRAME/TRAP OPERA TOR MAINTENANCE

The following areas (below) should be inspected regularly between loads and commodities.

• Doors (T op/sides/underside)

• Trap frame structure

• Roller bearings

• Gear rack

• Cross shaft and flange bearings

It is critical that the trap frame area be maintained properly for trouble free operation. Clean these
sections with a hand brush, compressed air (50 PSI max) or both between loads to avoid con­tamination. Do not use high pressure sprayer as bearings could be damaged.

T o maintain proper trap door operation and ease of opening, the mechanism must be properly
adjusted and lubricated.

The trap operator drive mechanism (gear rack and cross shaft gear) interfaces must be kept
properly aligned and free of debris and corrosion to enhance freedom of movement. Flange
bearings should be greased regularly , depending on frequency of operation. Timpte recommends
the operator grease bearings monthly (failure to do so may void warranty).

Use the following procedure to readjust the trap door and gear rack assembly .

AIR HAMMER (VIBRA TOR) MAINTENANCE

The air hammer employed to help dislodge commodity should be lubricated on a regular basis.
The air hammer manufacturer recommends a SAE 10 or lighter oil for this purpose. Frequency of
lubrication is directly related to volume of usage. The operator should lubricate the air hammers
(vibrators) prior to each use or maintain oil in reservoir if equipped with self-lubricating system.

NOTE: The operator must confirm that all air hammers are securely located in the mount­ing brackets and locked into place prior to usage. Failure to locate and lock air hammers
into position properly could result in serious personal injury or damage to the trailer. Do
not exceed 80 P.S.I. while operating piston vibrator. Failure to follow operating instruc­tions properly could void the warranty.

TROUBLE-SHOOTING:

1.Vibrator will not start:
a. Check to see that quick-opening valve is properly installed.
b. Vibrator should be within 5 feet of operating valve.
c. Be sure vibrator has adequate air pressure and volume

HUB AND BEARINGS

HUB MAINTENANCE

Check wheel studs for good condition – no stripped threads – no bent or loose studs. Replace any
broken or bent studs or studs with damage to the threads. When a broken stud is replaced, the
stud on each side of it should be replaced at the same time. If more than two studs on the same
hub are broken, replace all of the studs.

WHEEL BEARING INSPECTION

Periodic inspection of wheel bearings and lubricants as well as regular lubricant changes are
necessary for good maintenance and maximum wheel bearing life. The hub and/or wheel assembly
must be properly cleaned to obtain optimum bearing life. This step also applies to field service.
When adding or checking oil level, make certain cap and plug are clean. This step will minimize the
possibility of dirt and road grime entering the system.

WHEEL BEARING ADJUSTMENT

1. Install adjusting nut so that pin on nut faces away from the hub.

2. Tighten inner nut to 200 ft. lbs. while rot ating the hub in both directions.

3. Completely loosen the inner nut, then retighten to 50 ft. lbs. while rotating the hub in both
directions.

4. Loosen the inner nut ¼ turn. Do not include socket backlash in the ¼ turn.

5. Install the lock washer . If the hole in the lock washer is not aligned with inner nut pin, remove
the washer , turn it over and reinstall. If the washer hole is still not aligned with the pin, loosen
the inner nut slightly until the hole and pin are aligned.

Note: The washer may have to be reversed again with minimum loosening of the nut.

6. Install the jam nut; Torque to 300 ft-lbs.

7. Check the hub end play with a magnetic base and dial indicator .

a. Place the magnetic base and indicator on the end of the spindle. Touch dial indicator

stem to hubcap gasket face.

b. Slightly rotate the hub & drum in both directions while pushing inward until the dial

indicator reading does not change.
c. Set the dial to zero.
d. Slightly rotate the hub & drum in both directions while pulling outward until the dial

indicator reading does not change.
e. Read the end play from the dial indicator .

8. End play between .001 and .005 is acceptable.
a. If the end play is less than .001, loosen the jam nut; Repeat steps 1 through 8, and

retorque to 300 ft. lbs.

b. If the end play is greater than .005, increase the jam nut torque to 300 ft. lbs.

9. Repeat Step s 6 & 7 as necessary until the end play is within the accept able range.

10.Bend tabs on lock washer over opposite flats of the jam nut.

BEARING LUBRICANT

The lubricant change interval depends on the type of lubricant used; oil or semi-fluid grease. Oil
levels should be checked as part of the daily inspection. Oil should be changed whenever seals are
replaced, brakes are relined, or at least every 12 months or 100,000 miles. Fill hubs with new oil to
the level indicated on the hub window using HD80-90W heavy duty oil with an API rating of GL-15 or
GL-4.

CAUTION! DO NOT overfill oil. Oil seal damage may occur due to excessive

Grease lubricated wheel ends should be changed whenever seals are replaced, brakes are
relined or at least every 12 months or 100,000 miles with NLGI Grade 1 or 2 grease.

To install semi-fluid grease

1. Pack both bearings with grease by forcing grease into the cavities between rollers
and cage from the large end of the cone.

2. Apply a light coat of grease to the spindle bearing journals.

3. Install the inner bearing, inner seal and hub.

4. Fill the cavity between the bearing races with grease up to the smallest diameter of the
bearing cups.

5. Install the outer bearing and adjust end-play as noted in the “Wheel Bearing Adjustment
Procedure” section.

6. Apply a light coat of grease to the interior of the hubcap and wheel retention hardware
to indicate what lubricant is installed as well as to help prevent corrosion of these parts.

BRAKES

Proper maintenance of the brakes is vitally important. This includes lining inspections and brake
adjustments. A schedule for periodic adjustment, cleaning, inspection and lubrication of the brake
equipment must be made according to duty cycle and type of operation.

Brakes must be adjusted as frequently as required for correct operation and safety . The adjustment
must give correct clearance between the lining and drum, correct push rod travel, and correct bal­ance between the brakes. Improper or inadequate lubrication is the leading cause of dragging
brakes/premature brake wear.

Brakes must be cleaned, inspected, lubricated and adjusted every time the wheel hubs are re­moved.

During a major overhaul, the following parts must be carefully checked and replaced with genuine
replacement parts if required.

1. Backing plates or spiders for distortion and loose bolts.

2. Anchor pins for wear and correct alignment.

3. Brake shoes for wear at anchor pins or roller slots.

4. Camshaft and camshaft bushings for wear .

5. Shoe return springs for wear and loss of strength.

6. Brake linings for grease on the lining, wear , chip s, and loose rivets or bolts.

7. Drums for cracks, deep scratches, heat checking or other damage.

NOTICE:

Wheel bearings must be correctly adjusted before brake
adjustments are made.

NOTICE:

Brake linings must not be permitted to wear to the point
that the rivets or bolts touch the drum.

See the manufacturer’s maintenance manual for more information and details on brake main­tenance, repair and trouble shooting.

Air leaks at spring brake chambers, reservoir fittings, drain valves, drop hoses, and connections
can cause the air system to perform less efficiently and the compressor to cycle too frequently
and may eventually result in dragging brakes.

If you suspect air system problems in either service brakes or spring brakes, don’t hesitate –
service the brake system immediately;

Trouble shooting the air brake system:

• Use the “soap bubble” test at all connections throughout the air system to detect
external leaks

• Threaded connections at the ECU

• Threaded connections at the pressure protection valve

• Any and all push-in fittings

• Check for exhaust leaks at all valves to detect internal leaks.

• Check the actuator and spring brake push rod for proper movement in operational modes.

NOTE: Never splice air brake hoses within the air brake system. This action will void part or all of
the trailer warranty .

BRAKE CONTROLS

Proper operation of the brake system requires a good, clean seal between the glad hands. In­spect the rubber washer on the glad hands for damage. Inspect the glad hands for cracks in the
metal parts. The glad hands have a screen filter and must be cleaned. Check air hoses for cracks
and leaks. Check the operation of the brakes and slack adjusters. Drain the water from the air
brake system each day by opening the drain cocks on the bottom of the air tank(s). Periodically
check and clean the filter element on the air line filter, mounted directly behind the Control side
glad hand. Observe the ABS status indicator light for proper operation as found under the ABS
heading in the SAFETY section.

IN-LINE AIR FILTER

This trailer is equipped with an in-line air filter, Control side, which is located on the nose of the
trailer, to assist in protecting the air system brake valves. The number one cause of ABS valve failure
is contamination in the air supply from the tractor . This filter will help in minimizing those problems. To
operate properly and provide the most protection possible, the filter should be inspected and
cleaned every 3 to 4 months. Proper use and maintenance of the filter will help extend the life of the
ABS ECU and will extend the warranty on the ABS ECU.

NOTICE:

T railer is equipped with an in-line filter to

CHECKING SPRING BRAKES

Spring breaks must be inspected on a routine basis to insure proper operation. Inspection is
recommended a minimum of every 3 months or 25,000 miles.

WARNING! Always chock wheels to prevent the vehicle from rolling before per-

!

1. Check overall condition of the foundation brakes including drums, shoes, lining, retainers, return

springs, bushings and rollers. Replace any damaged or worn components per manufacturer’s
specifications.

2. Check for obvious structural damage to the spring brakes, brake adjusters, or cam shafts and

replace any damaged or worn components per manufacturer’s specifications.

3. Hook up appropriate air supply and release parking brakes. Apply and fully release Parking Brake

several times while watching for brake adjuster movement. Adjusters should apply and retract at
relatively the same distance for all wheel positions.

4. T o verify equal push rod movement, measure each push rod from the Face of the Air Brake Cham-

ber to the Center of the Clevis Pin with the brakes Fully Set or Parked. Apply air to the chambers to
release the parking brakes and re-measure all wheel positions. All strokes should be within 1/8" of
each other .

5. Applied Stroke at 90 to 100 psi can also be used to measure in a similar way as in step #4. Apply

Service Brakes instead of setting Spring (Emergency) Brakes and record before and after push
rod measurements. Measured push rod stroke should not exceed the recommended maximum
readjustment limit of 2" for Standard 30/30 chambers and 2 1/2" for Long Stroke 30/30 chambers.

forming any brake maintenance.

AUTOMATIC SLACK ADJUSTERS

Effective 10/20/94 all semi-trailers with air brake systems were required to be built with automatic
slack adjusters to assist in maintaining the braking system performance. The automatic slack
adjusters should be periodically checked to insure that they are performing correctly and should
be lubricated on a regular schedule or at least every six months.

The following procedure can be used to check the in-service adjustment of air chamber push rod
travel (adjusted chamber stroke) on trailer air brakes with automatic slack adjusters.

1. Connect an adequate air supply to the SUPPLY glad hand of the trailer’s air system.

2. Increase the air pressure to 100 psi minimum to release the auxiliary spring brake cham­bers.

3. Determine the size and type of brake chamber you are inspecting.

4. With the brakes NOT APPLIED measure the distance from the bottom of the air brake
chamber to the center of the large clevis pin on all wheel positions. Record each measure­ment.

5. Connect a second air supply to the CONTROL glad hand of the trailer’s air system.

6. Increase the air pressure of the second air supply to 85 to 90 psi to apply the service
brakes.

7. With the SERVICE BRAKES APPLIED measure the distance from the bottom of the air
brake chamber to the center of the large clevis pin on all wheel positions. Record each
measurement.

8. Calculate the adjusted chamber stroke of each brake. Subtract the dimension that was
measured in Step #3 from the dimension that was measured in Step #6. The difference
between the two dimensions is the adjusted air brake chamber stroke. The adjusted air
brake chamber stroke must not be greater than 2” for 30/30 chambers and 1 ¾” for 24/20
chambers. If the adjusted air brake chamber stroke is greater than the dimensions listed,
inspect the automatic slack adjuster for wear or damage. See manufacturer’s recommen­dations for repair or replacement.

WHEEL ASSEMBLIES

Inspect parts and components for damage. Replace any defective parts.
Use only correctly matched parts when assembling and installing wheels. Incorrect parts can

result in separation of the wheel components which can lead to an accident.
Assembling painted, dirty, or rusty components can prevent proper mating of parts. Make sure all

mounting surfaces are clean and free of rust, dirt, or excessive paint.
Make certain all tires are matched to the same rolling circumference per the tire manufacturer’s

instructions. Do not use tires that do not meet this criterion. Doing so may result in unstable
operation that can significantly reduce service life.

All components must be correctly installed and fasteners tightened to the recommended torque to
assure maximum service life in accordance with the manufacturer’s instructions. Failure to do so
may result in serious injury or death.

WHEEL INST ALLATION

Hub piloted disc wheels have stud holes that are drilled straight through the wheel. Pilot bosses
machined on the hub fit tightly into the center of the disc wheel. This supplies the alignment of the
wheel to hub. Hub Piloted wheels are secured to the hub with flanged nuts.

Installation of a Hub Piloted Wheel

1. Be sure not to mix Hub Piloted and Stud Piloted disc wheels.

2. Use the correct flange nuts to match your wheels. Failure to do so may lead to loose
wheels which significantly reduce product life and may result in a crash. Before proceeding
with the installation of the disc wheels make certain that you are using the proper flange
nuts. The Hub Piloted mounting uses M22 x 1.5mm pitch metric thread series nuts. The
stud standout should be at least 2.16”. All studs have right hand threads.

3. Rotate the hub so that one of the intermittent pilots is located at the top position.

4. Position the inner disc wheel over the studs and wheel pads being careful not to damage
the stud threads or the pilot diameter of the wheel. Make sure the disc wheel is flat against
the mounting surface and there is clearance between the disc wheel taper and the brake
drum.

5. Position the outer disc wheel over the studs and wheel pilot pads being careful not to
damage the stud threads or the pilot diameter of the wheel. Be sure the valve stems for
both the inner and outer tires are accessible.

6. Install the flange nuts and tighten to 50 ft. lbs following the sequence shown. Note: On two
piece flange nuts, apply a drop of oil between the nut and washer . Make sure the flange
washer is not seized to the nut. Do not lubricate the mounting surface of the drum or wheel,
or the stud threads.

7. Check both disc wheels for proper positioning on pilots and proper sealing against the
drum/hub assembly . If they are not, loosen the flange nuts and reposition the wheels.

8. Tighten the flange nuts to 450 to 500 f t. lbs. dry thread torque following the sequence below .

Recheck the torque after the first 50 to 100 miles of service and at every pre-trip inspection.

Do not climb under a raised trailer .
Do not leave a raised trailer unattended.
Avoid raising a loaded trailer whenever possible.

1. Position trailer on a level, hard surface capable of supporting the total vehicle weight
and lifting equipment.

2. Set brakes and block wheels at other locations to prevent movement.

3. If a loaded trailer must be raised for changing tires, take appropriate precautions to
reduce risk of tipping, load shifting, or structural damage. If necessary , use two lifting
devices and raise both sides of the trailer evenly to prevent leaning and tipping.

4. Position the jacks or lifting devices under the axle, as close to the outer end as pos­sible. Use care to avoid placement that will cause contact and damage to other com­ponents such as brake chambers, cam shafts, U-bolts, and slack adjusters.

5. Raise the trailer at a slow , steady rate until the tires to be removed are off the ground. If
using two lifting devices, raise both sides of the trailer evenly to avoid leaning and
tipping.

6. Position trailer supports under trailer frame or axle to prevent unexpected lowering of
the trailer.

7. Remove the nuts securing the tires and remove the tire(s) using a tire fork or similar
device to lift the tire(s).

8. Install the replacement tire(s). Refer to the appropriate section of the Owner’s Manual

AXLE ALIGNMENT

Proper axle alignment is a vital part of trailer maintenance. Failure to maintain proper alignment
may cause tire scrubbing and suspension component strain. Y our trailer’s alignment should be
checked regularly and the axles realigned when required to prevent unnecessary tire wear.

1. T o properly align the suspension make sure the trailer is unloaded. Free the suspension of
any “binds” by first pushing the trailer backwards and then pulling it forward a sufficient
distance. Check axle alignment with the trailer on a level surface with the trailer level both
side to side and front to back, with tires properly inflated, trailer securely restrained, trailer
brakes (service & parking) released and with the trailer ride height valve properly set (if an
air ride).

2. Check each dual tire set. Tires of each set must be matched to a maximum of 1/8” tire
radius. Air pressure must be the same in all tires.

3. Using a steel measuring tape, measure from the center point on the bottom of the king pin
to identical locations on each end of the front axle using a consistent amount of pressure on
the tape measure.

4. If these measurements differ by more than 1/16”, adjust one end of the front axle forward or
rearward until identical measurements are obtained on both ends.

5. After the front axle is aligned and secured, measure from the end of the front axle to the end
of the rear axle on each side.

6. If these measurements differ by more than 1/16”, adjust one end of the rear axle forward or
rearward until identical measurements are obtained on both ends.

Spring suspensions are equipped with screw adjusted torque arms located on the driver’s left
side of the trailer. Adjustment of the alignment is accomplished by turning the torque arm in or out,
depending on the adjustment required.

1. Loosen the radius rod clamp bolts.

2. Move the left end of the axle forward (shorten the alignment measurement) by turning the
torque arm to make it shorter.
Move the left end of the axle rearward (lengthen the alignment measurement) by turning the
torque arm to make it longer .

3. Check the alignment measurements. Repeat the adjustment in Step #2 as necessary .

4. When the axle is correctly aligned, tighten the radius rod clamp bolts to 130 ft. lbs. oiled or
170 ft. lbs. dry .

Note: Check the clamp bolt torque within the first 50 to 100 miles of operation following align­ment.

Air ride suspensions are equipped with mechanisms to allow the movement of one end of the axle
forward or rearward for the purpose of aligning the trailer axles.

Inspect the hanger pivot bushings as well as all other suspension components before adjusting the
alignment.

The SAF Holland RL-230 or RL-250 suspensions use a bolt at the suspension pivot
connection with an eccentric collar to allow for adjustment for axle alignment.

1. Loosen the 1 1/8” pivot bolt lock nut on the inside of the suspension hanger.

2. Rotate bolt head clockwise to move the axle forward (to shorten the alignment measure­ment) or rotate bolt head counter clockwise to move the axle rearward (to lengthen the
alignment measurement).

3. Snug the hanger bolts to 200 ft. lbs. and check the alignment measurements. Loosen the
nut and repeat the adjustments in Step #2 if necessary

4. When the axle is correctly aligned, re-torque the lock nut on the pivot bolt to 550 ft. lbs.

The SAF Holland CB2300 & CBX23 suspension with the Quik Align feature uses a bolt on
the front the suspension hanger to allow for adjustment for axle alignment.

1. Using a hand wrench, rotate the Quick Align bolt clockwise to shorten the alignment mea­surement or counter clockwise to lengthen the alignment measurement.

AIR-RIDE SUSPENSION SYSTEMS

See suspension manufacturer’s decals prominently displayed on trailer body and manufacturer
literature kit supplied with trailer for details and specific instructions on the care and maintenance
of the air ride suspension.

Retorque the suspension fasteners after the first 3 months of use or 5,000 miles of operation after
an alignment, at regular periodic maintenance checks and at every brake relining per the

manufacturer’s directions.

NOTE: Never move an air ride trailer without first fully inflating the air springs – failure to
do so could cause damage to the trailer and suspension and will void the warranty .

the spring suspension and make any adjustments necessary .

Components New Oiled Torque Clean Dry Torque
1 1/8-7 Rocker Bolt 590 ft. lbs. 790 ft. lbs.
1-14 Radius Rod Bolts 540 ft. lbs. 720 ft. lbs.
¾-16 U-Bolts 310 ft. lbs. 420 ft. lbs.
5/8-18 Radius Rod Clamp Bolt 130 ft. lbs. 170 ft. lbs.
5/8-18 Spring Retainer Bolt s 35 ft. lbs. 50 ft. lbs.

The axle alignment should be checked and corrected if necessary after this initial break in period.
Check all suspension bolts no less than every 4 months. They should be tightened to the above
torque specifications. (Remember lubricants or sealants on the threads reduce torque reading
and paint, corrosion, or road debris on the threads increase readings). Check for and replace
worn bushings in the equalizer and in the torque arm eye ends. Use a good rubber lubricant on
bushings before installation to prevent damage during installation. Be sure radius rod bolts are
tightened back to 540 ft. lbs. (oiled) after replacing any torque arm bushings, and tighten equalizer
rocker bolts back to 590 ft. lbs. (oiled) after replacing equalizer bushings. Check the equalizers to
see that there is no obstruction to their movement during operation. If equalizer movement is
restricted by an obstruction, the axle “walk” will not be sufficient and damage could result.

AXLE CLAMP GROUP AND SPRINGS -

1. Check the torque on the U-bolt nuts by alternately tightening opposing corners of the clamp
assembly.

See Figure 1.

a. When using 7/8” - 14 U-bolts, the nuts should be torqued to a dry level of 470 lb-ft.
b. When using 3/4” - 16 U-bolts, the nuts should be torqued to a dry level of 420 lb-ft.

Always carefully inspect the spring and axle
clampcomponents for any signs of wear or
cracks, andreplace if visible wear or cracks
are present.

RADIUS RODS -

2a. The 1” - 14 radius rod attachment bolts at the hangers
and spring seats should be tightened to a dry level of
720 lb-ft. of torque on both the adjustable and non-adjustable
radius rods. See Figure 2.

Loose operation of this bolt can result in wear requiring that new components be installed to avoid
structural damage. During your visual inspection, if you observe any visible wear or loosening in
the bushings, it is imperative that you immediately replace the radius rod bushing and bolt. Failure
to replace these components will result in damage to the hanger , spring seat, and/or radius rod.

2b. Next check the 1/2” - 20 radius rod clamp bolt, which should be tightened to a dry level of 85 lb-ft.
of torque. The 5/8” - 18 radius rod clamp bolt should be tightened to a dry level of 170 lb-ft of torque.
See Figure 2. If the clamp bold has not been properly maintained, then wear between the radius
rod screw and the eye end may be observed. If so, then the entire radius rod must be replaced.

Simply retightening or replacing the clamp bolt will not correct the problem.

ROCKER BUSHINGS -

3. The recommended torque values for the rocker bushing clamp bolts are different for each
model.

a. If you are working on the 7700 model suspension, the 5/8” -18 rocker step bolts should

be tightened to a dry level of 170 lb-ft of torque. See Figure 3a.

b. If you are working on the 9700 model suspension, the single 1 1/8” - 7 rocker bolt

should be tightened to a dry level of 790 lb-ft of torque. See Figure 3b.

During your check, if the bolts are loose a detailed inspection of the rocker is important to ensure
that no structural damage has occurred. One way this can be done is by raising the trailer until the
trailer weight is taken off the springs. If the rocker is displaced or if the joint is loose, then the rocker
should be removed and the rocker and/or rocker bushing be replaced. Again, visually inspect the
condition of all rocker/rocker hanger assembly components and replace if visible wear is present.

HANGERS -

4. Check all the spring retainer bolts found in the rockers and rear hangers. A dry value of 50 lb-f t
of torque should be maintained on all of these bolts. See Figure 4.

Loose fasteners that are allowed to operate for any period of time will result in irreversible suspen­sion damage and possible loss of vehicle control. Retightening a worn fastener will not cor-

rect a situation created by loose operation!

ELECTRICAL SYSTEM MAINTENANCE

Y our T impte trailer utilizes an internally grounded, automotive style electrical system that meets or
exceeds all of the requirements of FMVSS 108.

A 7-way plug is located on the front of your trailer . Each terminal carries current from your tractor
electrical source through a circuit to the various electrical devices on the trailer. Individual circuits
may be traced by the various wire colors. Listed below is a schedule of the color code of the
primary electrical circuits.

Blue – ABS Constant Power
Red – Stop Light s
Black – Red Clearance Lights
Brown – Amber Clearance Light s

Use dielectric grease for all electrical connections to prevent corrosion between electrical junc­tions and to enhance electrical conductivity . (Failure to do so may void warranty .)

Do Not splice any electrical harness conductor . Splices may create open circuits or create the
potential for “dead shorts” or “ground” issues within a circuit. Always replace damaged harnesses
and conductors promptly . Splicing or modifying the harness may void warranty .

CAUTION – FMVSS #121 safety standard for Air Brake System required as of
3/1/1997 that trailers supply constant power via the blue center pin of the 7 way

!

to the ABS system. As of 3/1/2001, all trailers were required to have an ABS
system that provided for activation of the system status warning lamp inside
the tractor cab.

Tractors and trailers using a single 7 way electrical connector will have
constant power for the ABS on the center pin when the key switch is “on” and
the ABS unit will communicate to the in cab system st atus warning lamp.

LANDING LEGS

LANDING GEAR LUBRICA TION IS IMPORTANT!

Your landing gear was adequately greased and packed with high quality lubricants when manufac­tured and will not require additional lubrication for the first five (5) year period of service and
operation. Following the initial five year period, it will be necessary to periodically supplement this
lubrication to maintain satisfactory performance for your particular application. Re-lubrication
should be part of your preventative maintenance program and should be done every month or
more often, if required.

For low temperature operations (under 20° F) use a lithium or an anhydrous calcium extreme
pressure grease that operates down to -65°F.
For cold weather operations, it is also recommended to fill the gearbox approximately 3/4 full with
grease. This helps minimize moisture accumulation, which can freeze, causing hard gear cranking.

For moderate temperature operations (20° F to 150° F) use a lithium or an anhydrous calcium
extreme pressure grease.

Lubricate as follows: (see FIGURE 1)

1. Fully retract the landing gear, then using high gear , lower the leg 2-3 turns and lubricate
the lift-screw assembly through grease fitting “A” (see landing gear legs shown below).
Apply ½ lb. of grease.
Distribute the lubrication by extending and retracting the leg several times.

2. Lubricate the gearbox, using grease fitting “B”. Apply ¼ lb. of grease

3. Lubricate the bevel gear using grease fitting “C”.

Apply ¼ lb. of grease.
