SUSPENSION IDENTIFICATION
Introduction
It’s important that the proper suspension model be chosen for the application in which it is to be used. The Ridewell Self-Steering (RSS) 233 Suspension series is a fully integrated, auxiliary axle suspension system available for truck and trailer applications.
PART NO:
The RSS-233T 13K Trailer Suspension System can be congured with either drum or disc brake axle as­semblies and an optional steering lock.
Refer to the engineering drawing for detailed infor­mation on the suspension system components and operating parameters.
Read through the entire Installation and Service Manual (ISM) before performing any installation or maintenance procedures.
Identication Tag
Ridewell suspension systems can be identied by the
Part Number and Serial Number listed on the serial
identication tags.

Notes on Self-Steering Option
Self-steering suspensions are designed to steer only in the forward direction. The suspension should be
raised o the ground or locked into a non-steering conguration during reverse travel to avoid damag-
ing the suspension.
Ridewell Suspensions strongly recommends the use of automated systems that raise/lock the lift-axle during reverse travel. For manual operations, Ride­well recommends the installation of a visual/audible indicator to assist the driver.
Use caution when maneuvering in reverse with the steering lock engaged. The driver should maintain slow maneuvering speeds and avoid extreme turns.
Failure to lift the suspension and-or engage the steering-lock during reverse travel can cause component damage and void the warranty.
The ISM uses two types of service notes to provide important safety guidelines, prevent equipment dam­age and make sure that the suspension system oper-
ates correctly. The service notes are dened as:
“NOTE”: Provides additional instructions or
procedures to complete tasks and make sure that the suspension functions properly.
Indicates a hazardous situation or unsafe practice that, if not avoided, could result in equipment damage and serious injury.

Prior to Installation
INSTALLATION
Refer to the engineering drawing to conrm dimen­sional requirements and the range of ride heights available.
Installations can vary and procedures should be
adapted for dierent vehicles, as needed.
• The Gross Axle Weight Rating (GAWR) is deter­mined by the system component with the lowest load rating. Please consult with tire, wheel, axle and brake manufacturers before installation to determine the GAWR.
If vehicle chassis modications are required, con­sult with the vehicle manufacturer to ensure that
such changes are permied.
• Welding or altering suspension components is not permied without the express wrien permission of Ridewell Suspensions.
Installer Responsibilities
The installer of the suspension has the sole responsi-
bility for proper aachment of the suspension system
to the vehicle chassis.
• The installer is responsible for locating the sus­pension system on the vehicle to provide the proper load distribution.
• The installer must verify that vehicle crossmem­bers are positioned to support the suspension at the installing location.
• It is the installer’s responsibility to determine that axle spacing conforms to any applicable federal and local bridge laws.
• The installer must verify that air reservoir volume requirements are met after suspension installa­tion. Consult the vehicle manufacturer or Federal Motor Vehicle Safety Standards (FMVSS) 121 for more information.
The installer must verify there is sucient clear­ance for proper functioning of the auxiliary suspension, air springs, brake chambers, steering components. axle (including axle to driveline) and tires.

Mounting the suspension to the trailer frame
Refer to the engineering drawing for the range of ride heights available as well as spacing and clearance requirements of the suspension.
All models of the RSS-233T 13K Trailer Suspension are shipped fully assembled. If the system is taken apart for installation, the components must be reas­sembled with the proper torque applied (Page 3).
Weld-On Installation Procedure
Recommended locations of customer-furnished ller
plates and supporting crossmembers for the suspen­sion hangers and air spring mounting plates are shown on the engineering drawing.
NOTE: A single air spring bridge assembly instead of
two air spring mounting plates is available on some models of the RSS-233T 13K Trailer Suspension.
The welding method used must develop
a minimum weld tensile strength of 70,000 PSI per
AWS specications.
1. Mark the desired location for the frame hangers and air spring mounting plates (or bridge assem-
bly) and customer-furnished ller plates on the frame. NOTE: For proper support, a crossmember
must be located within six inches of the leading or trailing edge of the frame hanger. Check the lo-
cation for sucient clearances in both the raised
and lowered positions of the suspension.
8. Perform nal assembly and inspection and check
the wheel toe seing (Page 5).
Failure to torque bolts/nuts of suspension
components to specications can result in failure of
the suspension and void the warranty.
Bolt-On Installation Procedure
Refer to the engineering drawing for the range of ride heights available,spacing and clearance requirements
of the suspension and bolting paern detail.
Bolts/nuts for aaching the suspension to the ve-
hicle are supplied by the installer. Grade 8 bolts and
anged lock nuts or lock nuts with hardened washers
are recommended.
other components located within the frame rail are
not aected by drilling.
Check to make sure that wires, hoses or
2. Weld customer-furnished ller plates, as needed,
to crossmembers with ¼” llet welds down the
length of the crossmember.
3. Weld the customer-furnished ller plates for the air spring mounting plates (or bridge assembly) to the frame and crossmember(s), as needed.
Weld the ller plates with ¼” llet welds down
the length of the crossmember.
4. Weld the hangers to the frame/ller plates with
1/4” llet welds completely around the hangers.
Stop the welds 1/2” from the corners and edges.
5. Weld the air spring mounting plates (or bridge assembly) to the frame/ller plates with 3/16” l­let welds all the way around the mounting plates/ bridge assembly.
6. If components have been removed for installa­tion, reinstall as shown on engineering drawing.
Torque to specications (Page 3).
7. Install/connect the air control kit (ACK) to the suspension. Check the air system installation for leaks and proper operation of controls (page 6).

Page 4 233T-Trailer-13K-ISM-RevC-10-19-18
Final Assembly and Inspection
1. Verify welds on hangers and air spring mount­ing plates. Verify that all suspension component
bolts/nuts are torqued to specications (Page 3).
2. Install wheels and tires.
When lowering an auxiliary axle on an unloaded vehicle, pressure to the load air springs must be reduced to below 10 psi. Failure to reduce the air pressure could cause the vehicle’s drive axles to rise from the ground and the vehicle could roll in an unsafe manner.
3. Check that tires are inated to recommended pressure. Check wheel hubs for proper level of lubricant recommended by the manufacturer.
4. Lift the axle to the raised position. Check the air system tubing and connections for leaks.
5. Check that wheels can rotate freely and that brakes and slack adjusters are properly adjusted.
6. Raise and lower the suspension assembly (wheels and tires installed) through the entire range of
travel. Make sure that sucient clearances for air
springs, brake chambers and other components has been provided.
7. Check the vehicle’s reverse travel options:
7.1 Check steer lock operation.
7.2 Check automated system (if installed) to make sure that suspension raises/locks wheels during reverse travel.
Failure to check reverse travel operations can result in component damage and void the suspension warranty.
Do not lower the auxiliary axle while the vehicle is moving in forward or reverse travel above 10 mph.
8. Check wheel toe-in seing and adjust, if neces­sary (between 1/32” and 3/32”).
Air springs pressure regulates axle load
The load capacity of the auxiliary axle is adjusted by increasing or decreasing the pressure to the air springs. By applying more air, the lift axle takes on a greater percentage of the load’s weight. The load capacity is decreased as the air pressure decreases.
Accurate readings of the load capacity can be ob­tained by parking a loaded vehicle over a calibrat­ed scale and lowering the axle onto the scale. The air pressure to the air springs is manually adjusted up or down to obtain the axle load weight at vari­ous air pressures.
Do not exceed the rated load capacity of the suspension system or other components. Ex­ceeding the capacity can cause component failure and void the warranty.
Check Wheel Toe Seing
1. Deate the air springs.
2. Lift the axle enough for tires to rotate freely. Sup­port with jack stands to ensure axle is level.
3. Position tires to point straight ahead. Spin each tire. Use a piece of chalk to mark a line on the center tread all the way around the tire.
4. Use the centerline mark to measure the distance from the front of the tire to the frame. Measure the distance from the back of the tire to the frame.
5. Subtract the front of the tire distance from the
rear distance to obtain the wheel toe seing.
Adjust Wheel Toe
1. Loosen clamps on both ends of the tie rod. Twist the tie rod forward/backward to move the front of the tire towards or away from the frame.
2. Continue rotating the tie rod until the proper toe-
in seing is achieved.
3. Torque tie-rod clamps to 60-80 ft-lb (81-108 N-m).
Wheel Toe Setting
Wheel toe is the relationship of the distance between the front of the tires and the distance between the rear of the tires on the same axle.
When the front distance is less than the rear distance, the wheels are in a “toe-in” (positive toe) condition.
The correct seing for the RSS-233 suspension should
be toe-in between 1/32” and 3/32”.

Install air system components
Connect the load and lift air springs and an air con­trol kit to the air system (Figure 2).
The air control kit (ACK) consists of a pressure regulator with a gauge connected to an air valve controlled by an electric switch or manual knob. The ACK allows the operator to control the air spring pressure so that the auxiliary axle can support dier­ent loads.
Ridewell has a number of manual/electric ACK
congurations available. Installation will vary by the type of conguration.
The installer is responsible for making sure that air system requirements comply with the appro­priate Federal Motor Vehicle Safety Standards.
