o. Maintain the horizontal position of cylinder , install the sleeve and clutch disk assembly on the cylinder; ensure the top of
washer and external hole of cylinder are in order until the sleeve can contact the C2 wave plate.
Caution:
For the C2 wave spring is compressed and the clutch disk can endure the weight of 19.6N. The dimension form the lower
side of C2 pressure disc to the gear selection steel plate is 1.4
1.8mm. if the clutch need to start the accuracy from the
top of pressure plate, then the accurate value should be the actual size of pressure plate plus 1.4
1.8mm.
p. Use the special tools to check the C4 clutch assembly. Refer to Figure 8.25.
Caution:
It should take out the clutch clearance assembly before immerse the assembly into the automatic transmission fluid
(ATF).
q. Use the gear selection plate to reach the correct specification. If need to install the new friction disk, it should remove the
clutch assembly and immerse the friction disk in the automatic transmission fluid for 5 minutes at least before the installation.
Reinstall the sleeve and clutch assembly and place it in the cylinder. Ensure the wave washer is arranged consisting with the
cylinder hole.
Install the clutch C2 disk in the cylinder according to the following procedure:

Check and adjustment
Check and adjustment of brake pedal
1. Check the correctness of height of pedal
Distance from pedal to lower front apron: 152mm, Operating stroke
of pedal push bar is 1mm.
a. Disconnect the brake lamp switch wire connector; loose the
tightened nut; rotate the brake switch to the position not contacted
to limit block of brake pedal
b. Loose the lock nut of operating connecting rod; use the thinnose
pliers to rotate the operating connecting rod to adjust the height
of brake pedal to the standard value; lock the block nut tightenedly
when reach the standard value.
c. Rotate the brake lamp switch to contact with the limit block of
brake pedal; then rotate 1/2
1 round continuously; tighten the
block nut;
d. Connect the wire connector of brake lamp switch;
e. The brake lamp should not be light when the brake pedal is
released.
3. Check the free stroke of pedal
Free stroke of pedal: 4
6mm
In the status of engine is stop, step on the brake pedal for 2
3 times
after eliminate effect of the brake assist, push down the brake pedal
by hand to just with the resistance, then measure its displacement
(free stroke). It should be in accordance with the standard value.

4. Adjust the stroke of pedal if necessary
a. Rotate the pedal push bar to adjust the free stroke if the stroke
length is improper.
b. Start the engine to confirm the free stroke of pedal.
c. Check the height of pedal after adjusts the free stroke of pedal.
d. The height difference of brake pedal and clutch pedal to front
apron is 0
8mm.
e. The height difference of brake pedal and accelerator pedal to the
front apron is 45
5mm.
Vacuum assist
Remarks:
Use the vacuum assist tester to check the operation of vacuum
assist if possible.
1. Operation inspection
a. Step on the brake pedal for several times before start the engine
and check the reserved distance which should not be changed.
b. Step down the brake pedal and start the engine. If the pedal
moves downwardly a little, then it means the normal operation;
if the brake pedal moves upwardly, then it means the brake
assist is damaged.
2. Air tightness inspection
a. Start the engine and shut off it after 1
2 minutes. Step down the
brake pedal slowly for several times. If the pedal moves
downwardly all long at the first time, but moves upwardly little
by little after second or third times, then it means the vacuum
assist has the sound air tightness. If the pedal height is without
variety, then it means the brake assist is damaged.
b. Step down the brake pedal when the engine is operating; then shut
off the engine but step down the pedal, if the pedal keeps the
stroke without variety within 30s, then it means the vacuum
assist has the sound tightness; if the brake pedal moves upwardly,
then it means the brake pedal assist is damaged.
