Areas of Importance
1. Clutch Rigid Pipe Installation
Before installing, check to make sure that the rigid pipe flare contact area is in good condition, the pipeline is
clean, and that there is no foreign materials.
2. Clutch Hose Installation
Check the surface of the clutch hose to make sure that there is no scuffing and that the pipeline is clean.
3. Coat grease on the U-joint of the pedal and the master cylinder.
4. Strictly adhere to the set torque guidelines when tightening the pipe fittings.
Rigid pipe and the master cylinder: M10 16±2 N·m
Clutch rigid pipe and hose: M10 16±2 N·m
5. While the clutch system is undergoing the exhausting process, make sure that all the air bubbles in
the pipeline are cleared out. Then check the brake fluid level in the reservoir, it should be between
MIN and MAX.
Troubleshooting
The numbers in the table represent the order of the possible malfunction causes, so be sure to check each part in
turn. If necessary, replace the part.

Clutch Master Cylinder Installation
Installation of clutch system is reverse to its removal, but
since the whole clutch system uses hydraulic assistance,
make sure to air bleed it after the installation is completed.
Detailed steps as follows:
(a) Plug one end of the long transparent connection hose
(about 0.5 m long) into the bottom of bleed screw, and
the other end into a fixed container.
(b) Loosen the bleed screw via the open end of the M8,
meanwhile ask the assistant to step on the clutch pedal
repeatedly until no air bubbles can be seen in the hose.
R e m a r k : R e s i d u a l a i r i n t h e c l u t c h s y s t e m h a s b e e n
completely exhausted.
(c) Lastly, lock the bleed screw.
Caution: Refilling the brake fluid reservoir should be
performed while air bleeding the clutch.
Clutch Pedal Removal
1. Remove the battery's negative cable.
2. Remove the glove box at the left of the dashboard.
3. Remove the cotter pin at the U-joint of the clutch
master cylinder, and separate the center pin and the
pedal lever.
4. Remove the clutch pedal bracket from the cowl.
5. Remove the clutch pedal.
(a) Move the clutch pedal to the maximum stroke position.
(b) Take down the return spring.
(c) Remove the bolts and nuts.
(d) Take the pedal lever down from the pedal bracket.
Clutch Pedal Installation
1. Install the clutch pedal.
(a) Install the return spring.
(b) Install the clutch pedal lever.
(c) Install the bolts and nuts.
Tightening torque: 30 N·m
(d) Put the pedal lever at the maximum stroke position and
connect it with the spring, in order to set the pedal to its
initial position.
2. Install the clutch pedal onto the 2 studs of the clutch
master cylinder.
Use a M13 wrench to tighten the clutch pedal brackets with
two M8 nuts.
Tightening torque: 23±3 N·m
3. Install the clutch master cylinder push rod with the U-
joint.
(a) Coat the contact areas between the center pin and the
U-joint pedal connector with multi-functional grease.
(b) In succession, join the U-joint (pedal connector) and
the clutch pedal lever with a cotter pin.
Caution: Insert the center pin into the pedal lever from
the left side of vehicle.
(c) Install the cotter pin onto the center pin.
4. Check and adjust the clutch pedal.
5. Connect the negative cable of the battery.

Clutch Pedal Examination and Adjustment
1. Check if the pedal height is correct.
Height from the carpet: 100-110 mm
2. Adjust the pedal height.
Loosen the lock nut and adjust the clutch pedal limit adjust-
ing bolt until its height is correct, and then tighten the lock
nut.
Tightening torque: 20 N·m
3. Check if the pedal free play is correct.
Step on the pedal until one can feel the resistance.
Pedal free play: 13.7 mm
4. Adjust the free play.
(a) Loosen the lock nuts of the clutch master cylinder and
rotate the push rod until the pedal reaches the correct
free play.
(b) Tighten the lock nuts.
Tightening torque: 20 N·m
(c) Recheck the clutch pedal height.

Areas of Importance
Removal
During removal, all components should be gently handled to avoid knocking, especially the joint surface.
All components should be placed in the proper order to avoid misplacing \
and mistaking.
Installation
1. Clean all parts before installation (except rubber pieces and gaskets)\
.
2. All oil seals, shaft retainers, and elastic pins should not be reused.
3. All rubbing surfaces should be coated with lubricant, and the lips of all oil seals should be coated with
grease.
4. During installation of the bearings, do not use any kind of rolling element to transmit pressure, and
make sure not to tilt it.
5. During the installation of synchronizer components, the two sides of the spring piston's openings
should alternate.
6. When the transmission is operating under normal working conditions, there should be no lubricant
leakage from any of the parts.
Transportation and storage
1. When transporting a transmission, make sure the conditions are dustproof and rainproof, as well as
take proper care not to damage it due to jolting, shaking, removal, or i\
nstallation.
2. Transmission assembly should be stored in a ventilated, dustproof, and dr\
y place.
3. Users with special transportation or storage requirements should have another discussion to reach an
agreement on this matter in the supply contract.
