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.

037A Transmission’s Overall External Schematics
The 037A transmission is a step mechanical transmission with differential, two-shaft front wheel drive
application. The forward gear has adopted the inertia synchronizer gear-shifting mechanism, which offers
smooth and easy gear shifting, reduces noise dramatically, and improves the service life of the gear - important
in achieving the overall economical efficiency. Regarding its control mechanism, the set steel ball and spring
allow the shifting gear to be quick, accurate with solid handling. The 5th gear transmission is equipped with an
interlocking mechanism to prevent accidental switching to reverse, to im\
prove driving comfort and reliability.

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.
