WARNING
When working on your vehicle, observe the following general precautions to prevent death, personal injury and/or
property damage in addition to the particular DANGERS, WARNINGS, CAUTIONS and NOTICES in each chapter.
•Always wear safety glasses or goggles to protect your eyes.
•Remove rings, watches, ties, loose hanging jewelry and loose clothing before starting work on the vehicle.
•Bind long hair securely behind the head.
•When working on the vehicle, apply the parking brake firmly, place the gear shift lever in "Neutral" or "N" and
block the wheels.
•Always turn off the starter switch to stop the engine, unless the operation requires the engine running. Remov-
ing the key from the switch is recommended.
•To avoid serious burns, keep yourself away from hot metal parts such as the engine, exhaust manifold, radia-
tor, muffler, exhaust pipe and tail pipe.
•Do not smoke while working on the vehicle since fuel, and gas from battery are flammable.
•Take utmost care when working on the battery. It contains corrosive sulfuric acid.
•Large electric current flows through the battery cable and starter cable. Be careful not to cause a short which
can result in personal injury and/or property damage.
•Read carefully and observe the instructions specified on the jack before using it.
•Use safety stands to support the vehicle whenever you need to work under it. It is dangerous to work under a
vehicle supported only by a jack.
•If it is necessary to run the engine after the hood is raised (tilted), make sure that the parking brake is firmly
applied, the wheels are blocked, and the gear shift lever is positioned in "Neutral" before staring the engine.
•Run the engine only in a well-ventilated area to avoid inhalation of carbon monoxide.
•Keep yourself, your clothing and your tools away from moving parts such as the cooling fan and V-belts when
the engine is running.
•Be careful not to damage lines and hoses by stepping or holding your feet on them.
•Be careful not to leave any tool in the engine compartment. The tool may be hit by moving parts, which can
cause personal injury.

GENERAL INTRODUCTION (CHASSIS)GN02–3
TOWING
•When being towed, always place the gear shift lever in "Neutral" and release the parking brake completely. In order to
protect the bumper, fit a protection bar against the lower edge of the bumper and put a wood block under the frame near
the No. 1 cross member when attaching the towing chain. Never lift or tow the vehicle if the chain is in direct contact with
the bumper.
1.Towing procedures
(1)Make sure that the propeller shaft of the vehicle to be towed is removed. When the differential gear or rear axle shaft is
defective, remove both right and left rear axle shafts, then cover the hub opening to prevent loss of axle lubricant and
entry of dirt or foreign matter.
(2)Use a heavy duty cable or rope when towing the vehicle. Fasten the cable securely to the towing hook on the frame.
(3)The angle of pulling direction of the cable fastened to the towing hook must not exceed 15 in horizontal and vertical
directions from the straight ahead, level direction. Avoid using the hook in a way that subjects it to jerk, as in towing a
vehicle trapped in a gutter.
(4)Keep the gear shift lever in Neutral.
(5)Make sure that the starter switch is kept in the "ON" position, if the engine is not running.
(6)Make sure that the engine of the towed vehicle is kept running. If the engine is off, no compressed air/ no vacuum will be
available for the brake. This is dangerous, as the brake system does not function if the engine is not running.
In addition, the power steering system will not function. The steering wheel, therefore, will become unusually hard to turn,
making it impossible to control the vehicle.
(7)Note that the engine brake and exhaust brake cannot be applied, if the propeller shaft is removed.
(8)Make a slow start to minimize shock. Towing speed should be less than 30 km/h {18 mile/h}.
2.If the engine of the towed vehicle is defective, make sure that the vehicle is towed only by a tow truck designed
for that purpose.
(1)Front end towing (with front wheels raised off the ground)
When towing from the front end with the front wheels raised off the ground, remove the rear axle shafts to protect the
transmission and differential gears from being damaged. The hub openings should be covered to prevent the loss of axle
lubricant or the entry of dirt or foreign matter. The above-mentioned precautions should be observed for vehicles
equipped with either manual or automatic transmission, and for even short distance towing. After being towed, check and
refill the rear axle housing with lubricant if necessary.
(2)Rear end towing
When being towed with the rear wheels raised off the ground, fasten and secure the steering wheel in a straight-ahead
position.
CLEAN AIR ACT
1.Heavy-duty engine rebuilding practices.
§ 86.004-40
•The provisions of this section are applicable to heavy-duty engines subject to model year 2004 or later standards and are
applicable to the process of engine rebuilding (or rebuilding a portion of an engine or engine system). The process of
engine rebuilding generally includes disassembly, replacement of multiple parts due to wear, and reassembly, and also
may include the removal of the engine from the vehicle and other acts associated with rebuilding an engine. Any deviation
from the provisions contained in this section is a prohibited act under section 203(a) (3) of the Clean Air Act (42 U.S.C.
7522(a) (3)).
(1)When rebuilding an engine, portions of an engine, or an engine system, there must be a reasonable technical basis for
knowing that the resultant engine is equivalent, from an emissions standpoint, to a certified configuration (i.e., tolerances,
calibrations, specifications) and the model year(s) of the resulting engine configuration must be identified. A reasonable
basis would exist if:
a. Parts installed, whether the parts are new, used, or rebuilt, are such that a person familiar with the design and func-
tion of motor vehicle engines would reasonably believe that the parts perform the same function with respect to emissions control as the original parts; and
b. Any parameter adjustment or design element change is made only:
In accordance with the original engine manufacturer's instructions; or
Where data or other reasonable technical basis exists that such parameter adjustment or design element change,
when performed on the engine or similar engines, is not expected to adversely affect in-use emissions.
(2)When an engine is being rebuilt and remains installed or is reinstalled in the same vehicle, it must be rebuilt to a configu-
ration of the same or later model year as the original engine. When an engine is being replaced, the replacement engine
must be an engine of (or rebuilt to) a configuration of the same or later model year as the original engine.
Page 10
GENERAL INTRODUCTION (CHASSIS)GN02–4
(3)At time of rebuild, emissions-related codes or signals from on-board monitoring systems may not be erased or reset with-
out diagnosing and responding appropriately to the diagnostic codes, regardless of whether the systems are installed to
satisfy requirements in § 86.004-25 or for other reasons and regardless of form or interface. Diagnostic systems must be
free of all such codes when the rebuilt engine is returned to service. Such signals may not be rendered inoperative during
the rebuilding process.
(4)When conducting a rebuild without removing the engine from the vehicle, or during the installation of a rebuilt engine, all
critical emissions-related components listed in § 86.004-25(2) not otherwise addressed by paragraphs (1) through (3) of
this section must be checked and cleaned, adjusted, repaired, or replaced as necessary, following manufacturer recommended practices.
(5)Records shall be kept by parties conducting activities included in paragraphs (1) through (4) of this section. The records
shall include at minimum the mileage and/or hours at time of rebuild, a listing of work performed on the engine and emissions-related control components including a listing of parts and components used, engine parameter adjustments, emissions-related codes or signals responded to and reset, and work performed under paragraph (4) of this section.
a. Parties may keep records in whatever format or system they choose as long as the records are understandable to an
EPA enforcement officer or can be otherwise provided to an EPA enforcement officer in an understandable format
when requested.
b. Parties are not required to keep records of information that is not reasonably available through normal business prac-
tices including information on activities not conducted by themselves or information that they cannot reasonably
access.
c. Parties may keep records of their rebuilding practices for an engine family rather than on each individual engine
rebuilt in cases where those rebuild practices are followed routinely.
d. Records must be kept for a minimum of two years after the engine is rebuilt.
2.Maintenance instructions.
§ 86.010-38
(1)For each new diesel-fueled engine subject to the standards prescribed in § 86.007-11, as applicable, the manufacturer
shall furnish or cause to be furnished to the ultimate purchaser a statement that
"This engine must be operated only with ultra low-sulfur diesel fuel (meeting EPA specifications for highway diesel fuel, including a 15 ppm sulfur cap)."

PRECAUTIONS FOR ELECTRICAL SYSTEM
1.REMOVING THE BATTERY CABLE
•Be sure to wait for at least ten minutes after the starter key is
turned to "LOCK" position before you disconnect the battery terminals from the battery, as the vehicle data is recorded on ECU
and DCU starts working for the exhaust gas after treatment after
the starter key is turned to "LOCK" position. Otherwise, the vehicle data will not be recorded on ECU properly and DCU will not
complete working properly, which may result in the malfunction
of DPR system and DEF-SCR system.
•The MIL (malfunction indicator light) may come on when the
starter key is turned to "ON" position again, even if you wait for
at least ten minutes before disconnecting the battery terminals
from the battery after the starter key is turned to "LOCK" position. In this case, use HINO DX Ⅱ to clear the DTC (P204F and
P068A), to turn off the MIL and to conduct DPR regeneration
manually.
(1)Before electrical system work, remove the cable from the minus termi-
nal of the battery in order to avoid burning caused by short-circuiting.
(2)To remove the battery cable, fully release the nut to avoid damage to
the battery terminal. Never twist the terminal.
2.HANDLING OF ELECTRONIC PARTS
(1)Never give an impact to electronic parts of a computer or relay.
(2)Keep electronic parts away from high temperatures and humidity.
(3)Never splash water onto electronic parts in washing the vehicle.
(4)Do not remove the harness connector, electric component box, and
cover except for repair and inspection.
If removal is necessary, pay attention that water and foreign matters
do not attach or enter to the connector, terminals, electric component
box, and cover.
In restoration, make sure there is no attachment or entry of water and
foreign matters and mount them properly, because it causes degradation of waterproof function.
3.HANDLING OF WIRE HARNESS
(1)Perform marking on a clamp and a clip and secure then in original
position so that the wire harness will not interfere with the end and
acute angle section of the body and a bolt.
(2)To attach a part, take care not to bite the wire harness.

4.HANDLING OF CONNECTOR
(1)To remove a connector, hold the connector (indicated by an arrow in
the figure) to pull it out. Never pull the harness.
(2)To remove a connector with lock, release the lock then pull it out.
(3)To connect a connector with lock, insert it until it clicks.
(4)To insert a test lead into the connector, insert it from behind the con-
nector.
(5)In case it is difficult to insert a test lead from behind the connector,
prepare a harness for inspection and perform inspection.
5.INSTALLATION OF BATTERY DISCONNECT SWITCH
•Installation of the battery disconnect switch on the power supply
circuit for the dosing control unit of DEF-SCR (DCU) may dam-
age or result in the malfunction of DEF-SCR system.
•Be sure to read and follow the procedures and instructions on
the service bulletin before the installation of the battery discon-
nect switch.
6.HANDLING OF BATTERY DISCONNECT SWITCH
•Wait for at least one minute before using the battery disconnect
switch after the starter key is turned to "LOCK" position.
Otherwise, the vehicle data will not be recorded on ECU properly,
which may result in the malfunction of DPR system.

PRECAUTIONS FOR ELECTRIC WELDING
1.PRECAUTION FOR ELECTRIC WELDING
Electrical components such as the alternator and tachograph are
directly connected to the battery and one end is earthed to the
chassis frame. Under these conditions, welding current will flow
back along the earth circuit if electric welding is carried out and
damage may be caused to the alternator, tachograph, electrical
components, etc. Consequently, the following precautions are
always to be taken during welding.
(1)Disconnect the earth terminal of the battery at the frame fitment and
earth the welding equipment securely to the frame itself. (Do not fit the
welding equipment earth to such things as the tire rims, brake pipes
or fuel pipes and leaf spring, etc.)
a. Turn the starter switch off.
b. Disconnect the negative terminal of the battery.
c. Earth welding equipment securely, near to the area to be welded.
d. Put back battery negative ground as original condition.
e. Finally check the functioning of all instruments.

To the tapered thread of the air pipe joint is applied the sealant "LOC-TITE
#575". Follow the procedure below to remove/attach the piping.
1.REMOVAL
(1)The sealant (LOCTITE #575) has a high sealing capability. The return
torque of taper joint is about 1.5 times as high as the initial tightening
torque. To remove the joint, use a longer wrench.
(2)For replacement of joint in a place with poor workability, remove the
auxiliaries with the joint attached then remove the joint.
2.ATTACHING
(1)To apply sealant (LOCTITE #575), use waste and thinner to wipe the
dirt off the sealing section, directly apply the sealant by a quarter turn
(three ridges) starting from the second ridge from the tip, then assemble in accordance with the tightening torque table below.
Wipe dirt off the mating part (female screw) before tightening it.
In case the sealant has entered your eye or attached to your skin,
wash it away in running water.

2.INSTALLATION OF A CAULKING JOINT
•Press in the tube so that it does not move (will not come out), and
tighten the sleeve nut with the tightening tool to the torque shown in
the following table.
4.ASSEMBLING THE CAULKING JOINT (AFTER THE TUBE HAS
FIRST BEEN REMOVED FROM THE JOINT AND THEN REINSTALLED IN THE SAME PLACE)
(1)Make aligning marks on the connector and union to mark their posi-
tions before loosening the nut.
(2)When re-assembling the joint, tighten the nut until the pre-disassem-
bly position (position of aligning marks) is reached, and then tighten
the nut 60 more.
(3)Always check air leakage after assembling the joint. If air is leaking
from the joint, continue tightening the sleeve nut until the leak stops.
(4)If the air leak does not stop, replace the tube, sleeve, and insert with
new parts. If the air leak still continues, replace the nut and connector
/ union.
NOTICE
•During repair or other work, make sure the temperature limit of
the nylon tube is within -40-90C, especially during paint drying
work.
•During boring, welding, sanding, and other work, protect nylon
tubes from tools, cuts, heat sources, and sparks, or remove the

METRIC FASTENERS
1.Most threaded fasteners on the Hino trucks series are metric.
Be careful not to mix them up with threaded fasteners using the
inch system.
Mismatched or incorrect bolts, nuts and screws can cause damage or malfunction, resulting in personal injury and/or property
damage.
2.When bolts, nuts and screws are removed from the vehicle, they
should be kept for reuse whenever possible.
If they are not re-usable, parts that are equivalent to the original
parts in dimensions, strength, and thread pitch must be
selected.
3.Most original bolts are marked with identification numbers indicating the strength of the bolts. The markings are shown below.
4.When replacing bolts, be careful to use bolts with the same
markings as the original bolts.

(1)As a rule, vehicle must be in an unloaded condition and never jack up
or lift up the vehicle with things of heavy weight.
(2)If removing any things of heavy weight like the engine and transmis-
sion, the center of gravity of the vehicle moves. Therefore, place a balance weight so as to keep it from rolling, or hold the jacking support
location using the transmission jack.
2.NOTICE FOR USING 4 POST LIFT
(1)Follow the instruction manual for a safety operation.
(2)Do not damage tires or wheels with a free wheel beam.
(3)Using a wheel stopper, fix the vehicle.
3.NOTICE FOR USING JACK AND SAFETY STAND
(1)Work in a flat place using a wheel stopper all the time.
(2)Support the specified location with a jack and safety stand accurately.
(3)Do not work or leave the vehicle supported only by a jack. Be sure to
support the vehicle together with a safety stand.
(4)Be careful and accurate in jacking up and down the vehicle.
(5)Care must be taken when jacking up and supporting the vehicle. Be
sure to lift and support the vehicle at the proper locations.
•Cancel the parking brake on a level place and shift the transmission in
Neutral.
•When jacking up the front wheels of the vehicle at first place stoppers
behind the rear wheels.
•When jacking up the rear wheels of the vehicle at first place stoppers
behind the front wheels.
•When either the front or rear wheels only should be jacked up, set
safety stands and place stoppers in front and behind the other wheels
on the ground.
•After the vehicle is jacked up, be sure to support it on the safety
stands. It is extremely dangerous to perform any work on a vehicle
raised on a jack alone, even for a small job that can be finished
quickly.

SYMPTOM SIMULATION
EN00Z0002A200003
HINT
The most difficult case in troubleshooting is when no problem symptoms occur. In such a case, a thorough problem analysis must be carried out. A simulation of the same or similar conditions and
environment in which the problem occurred in the customer's vehicle
should be carried out. No matter how much skill or experience a technician has, troubleshooting without confirming the problem symptoms will lead to important repairs being overlooked and mistakes or
delays.
For example:
With a problem that only occurs when the engine is cold or as a result
of vibration caused by the road during driving, the problem can never
be determined if the symptoms are being checked on a stationary
vehicle or a vehicle with a warmed-up engine. Vibration, heat or water
penetration (moisture) is difficult to reproduce. The symptom simulation tests below are effective substitutes for the conditions and can
be applied on a stationary vehicle. Important points in the symptom
simulation test: In the symptom simulation test, the problem symptoms as well as the problem area or parts must be confirmed. First,
narrow down the possible problem circuits according to the symptoms. Then, connect the tester and carry out the symptom simulation
test, judging whether the circuit being tested is defective or normal.
Also, confirm the problem symptoms at the same time. Refer to the
problem symptoms table for each system to narrow down the possible causes.
1.VIBRATION METHOD: When malfunction seems to occur as a
result of vibration.
(1)PART AND SENSOR
Apply slight vibration with a finger to the part of the sensor suspected
to be the cause of the problem, and check whether or not the malfunc-
tion occurs.
NOTICE
Applying strong vibration to relays may open relays
(2)CONNECTORS
Slightly shake the connector vertically and horizontally.
(3)WIRE HARNESS
Slightly shake the wire harness vertically and horizontally.
HINT
The connector joint and fulcrum of the vibration are the major areas
that should be checked thoroughly.
2.HEAT METHOD: When a malfunction seems to occur when the
area in question is heated.
(1)Heat the component that is the possible cause of the malfunction with
a hair dryer or similar device. Check if the malfunction occurs.
NOTICE
•Do not heat to more than 60C (140F). Exceeding this tempera-
ture may damage components.
•Do not apply heat directly to the parts in the ECU.
Page 41
GENERAL INTRODUCTION (CHASSIS)GN02–35
SHTS00Z000200051
3.WATER SPRINKLING METHOD: When a malfunction seems to
occur on a rainy day or in high-humidity.
(1)Sprinkle water onto the vehicle and check if the malfunction occurs.
NOTICE
•Never sprinkle water directly into the engine compartment. Indi-
rectly change the temperature and humidity by spraying water
onto the front of the radiator.
•Never apply water directly onto the electronic components.
HINT
If the vehicle has or had a water leakage problem, the leakage may
have damaged the ECU or connections. Look for evidence of corrosion or short circuits. Proceed with caution during water tests.
4.HIGH ELECTRICAL LOAD METHOD: When a malfunction seems
to occur when electrical load is excessive.
(1)Turn on the heater blower, headlight, rear window defogger and all
other electrical loads. Check if the malfunction reoccurs.

EACH OTHER. WHILE PERFORMING THIS TASK, YOU MUST
ALSO ENSURE THAT THE YOKE FINGERS REMAIN IN THE UP
POSITION UNTIL THEY CAN BE ROTATED OVER THE RELEASE
BEARING HOUSING INTO THEIR FINAL POSITION.
•Do not use the cross-shaft release lever (or a pipe over it) to pull
the transmission into its final position.
•Do not excessively force the transmission into the clutch assem-
bly or engine housing. If it does not enter freely, investigate the
cause of the problem and make any necessary changes.
•If the input shaft will not slide into the discs, they may need to be
repositioned. Do not let the transmission drop or hang unsupported in the driven discs.
This can cause the discs to become distorted and the clutch will
not release.

After installing the pilot bearing, ensure that it rotates smoothly.
2.CHECK THE FOLLOWING ITEMS FOR WEAR REPLACE ANY
WORN COMPONENTS.
(1)Cross-shafts and bushings
NOTICE
Excessive wear at these points can cause a side loading condition.
Also, inspect the remaining pivot points of the linkage for excessive
wear.
(2)Release yoke fingers
(3)Splines on the input shaft
NOTICE
Any wear on the splines will prevent the newly installed driven discs
from sliding freely, thus causing poor release (clutch drag). Select a
disc out of the new installation and slide it full length on the transmission splines. This will detect a twisted input shaft. Replace input shaft
if disc does not freely slide.

(1)Remove the two (2) guide studs and replace with the remaining
mounting bolts with lockwasher. Using a torque wrench, progressively
tighten the eight (8) mounting bolts using the following crisis-cross
pattern. Starting at lower left.
Failure to tighten these bolts in this manner can:
•Prevent the clutch cover from "centering" into the pilot area of
the flywheel.
•Cause permanent damage to the clutch cover (i.e. become
cracked or broken).
•Cause the clutch assembly to be out-of balance with the fly-
wheel.

EACH OTHER. WHILE PERFORMING THIS TASK, YOU MUST
ALSO ENSURE THAT THE YOKE FINGERS REMAIN IN THE UP
POSITION UNTIL THEY CAN BE ROTATED OVER THE RELEASE
BEARING HOUSING INTO THEIR FINAL POSITION.
•Do not use the cross-shaft release lever (or a pipe over it) to pull
the transmission into its final position. Doing so may release the
clutch and "overstroke" the release bearing. The SOLO will
incorrectly "set" the release bearing position too close to the
transmission and cause the wear indication tab to move to 1/3-1/
2 the distance towards the "REPLACE" position.
•Do not excessively force the transmission into the clutch assem-
bly or engine housing. If it does not enter freely, investigate the
cause of the problem and make any necessary changes.
•If the input shaft will not slide into the discs, they may need to be
repositioned. If the clutch is to be unbolted from the flywheel, reinstall the shipping bolts and tighten one turn past contact with
the clutch. Now the installation shaft can be installed to reposition the discs and the clutch bolts re-torqued. Remove the shipping bolts to clamp the discs.
•Do not let the transmission drop or hang unsupported in the
driven discs.
This can cause the discs to become distorted and the clutch will
not release.

•Prevent the clutch cover from "centering" into the pilot area of
the flywheel.
•Cause permanent damage to the clutch cover (i.e. become
cracked or broken).
•Cause the clutch assembly to be out-of balance with the fly-
wheel.

9.USING A 1/4" (6 mm) DIAMETER FLAT NOSE PUNCH, LIGHTLY
TAP EACH OF THE FOUR (4) POSITIVE SEPARATOR PINS
TOWARD THE FLYWHEEL. PERFORMING THIS STEP WILL VERIFY THAT ALL FOUR (4) PINS ARE FLUSH AGAINST THE FLYWHEEL.
Failure to perform this step properly may cause the clutch to drag
(clutch does not release). Excessive force can damage the pins and
cause a release problem
NOTICE
The four (4) pins can also be set through the inspection opening of
the transmission bell housing if they were not to set prior to transmission installation.

12. WHILE MOVING THE TRANSMISSION FORWARD, ROTATE THE
OUTPUT SHAFT OF THE TRANSMISSION UNTIL THE SPLINES
OF BOTH THE INPUT SHAFT AND THE DISC(S) MESH WITH
EACH OTHER. WHILE PERFORMING THIS TASK, YOU MUST
ALSO ENSURE THAT THE YOKE FINGERS REMAIN IN THE UP
POSITION UNTIL THEY CAN BE ROTATED OVER THE RELEASE
BEARING HOUSING INTO THEIR FINAL POSITION.
•Do not use the cross-shaft release lever (or a pipe over it) to pull
the transmission into its final position. Doing so may release the
clutch and "overstroke" the release bearing. The SOLO will
incorrectly "set" the release bearing position too close to the
transmission and cause the wear indication tab to move to 1/3-1/
2 the distance towards the "REPLACE" position.
•Do not excessively force the transmission into the clutch assem-
bly or engine housing. If it does not enter freely, investigate the
cause of the problem and make any necessary changes.
•If the input shaft will not slide into the discs, they may need to be
repositioned. If the clutch is to be unbolted from the flywheel, reinstall the shipping bolts and tighten one turn past contact with
the clutch. Now the installation shaft can be installed to reposition the discs and the clutch bolts re-torqued. Remove the shipping bolts to clamp the discs.
•Do not let the transmission drop or hang unsupported in the
driven discs.
This can cause the discs to become distorted and the clutch will
not release.

1.ADJUST LINKAGE
(1)Adjust the clutch linkage until the yoke fingers contact the release
bearing (zero free-play in the cab).
(2)Loosen the lock nut and turn the push rod counterclockwise until the
release bearing contacts the release lever plate or release lever.
(3)Fully press the pedal up to 5 times to move the release bearing
slightly closer to the transmission and gain free-play in the cab.
2.ADJUST THE FREE TRAVEL
(1)Turn the push rod counterclockwise until the release bearing contacts
the release lever plate or release lever.
(2)Turn the push rod clockwise about 3 1/3 turns.

LUBRICATION (EATON SAS1402 and SOLO1402)
1.RELEASE BEARING
(1)The cast iron bearing housing will be equipped with either a standard
grease fitting or a lube tube extension. If a lube tube is not present, it
is necessary to remove the inspection cover to gain access to the
grease fitting. Apply grease until it purges from the rear of the housing.
2.RELEASE BEARING WEAR PADS
(1)Where the release fork contacts the bearing housing; there are small
hardened steel pads. Apply a small amount of grease to the wear
pads where the clutch release fork contacts.
3.CROSS-SHAFT BUSHINGS
(1)Lubricate both the left and the right cross-shaft bushings.
4.PILOT BEARING
(1)The pilot bearing inside the flywheel is a sealed for life bearing and
requires no lubrication.
RECOMMENDED LUBRICATION
Use a lithium soap base E.P. (Extreme Pressure) grease with a minimum of
+325 degree F operating range. It must meet the N.L.G.I.'s Grade 2 or 3
specs.
Incorrect grease and improper lube procedures will cause bearing
failures, bushing wearout, yoke tip and bearing wear pad wear.
