Overview of the entire car-5
The friction, disc, single-diaphragm spring clutch, hydraulic control mechanism. The external diameter of friction disc D=225mm,
internal diameter d=150mm, material is F810.
Adjustment of clutch pedal:
1. Measure the height of clutch pedal (from pedal pad surface to floor) and free stroke of clutch pedal (fork bar pin clearance).
Standard height of clutch pedal: flush with the brake pedal, free stroke of clutch pedal is 5-15mm;
2. Readjust the free stroke of pedal after adjust the height of pedal; rotate the push bar to the standard value, then fix the bolt
and nut;
3. If the free stroke of clutch pedal is not within standard value, it should rotate the adjusting bolt to standard value, then fix
the bolt and nut. Do not move the push bar to main cylinder when adjust the free stroke of pedal;
4. If the free stroke of clutch pedal and clearance between the clutch pedal and floor when the clutch is disengaged de not
consist with the standard, this may by caused by the air in hydraulic system and failure of main cylinder or clutch. It can
discharge the air of system or dissemble and inspect the main cylinder or clutch.

Inspection and adjustment of clutch pedal
1. Check the correctness of pedal height and stroke of push rod
The pedal height starting from the meter: LHD 157.5mm
The push pole travel at the top of the pedal: RHD 151.0mm
If not correct, adjust the pedal height and push rod stroke.
2. Adjust the pedal height and stroke of push bar if necessary
a. Screw off the locknut, rotate the locking bolt until to the correct
height.
Screw on the locknut.
b. Screw off the locknut, rotate the push rod until the stroke of push
rod is correct.
Screw on the locknut.
3. Check the correctness of free stroke of pedal
Step on the pedal lightly until fell the clutch start to generate the
resistance.
Free stroke of pedal: 5
15mm
4. Adjust the free stroke of pedal if necessary
a. Screw off the locknut, rotate the push rod until the free stroke is
correct.
b. Tighten the lock nut
c. Check the height of the pedal after adjusts the free stroke of pedal.
d. On the condition that ensure the free stroke of clutch pedal assembly:
The height difference between the brake pedal, clutch pedal and the
front apron is 0
8mm.
Air discharge of clutch
Remarks: It should discharge the air if there is residual air in the
clutch system.
Caution: Do not leave the clutch liquid on the painted surface,
otherwise it should be washed off immediately.
Fill the brake fluid in the clutch storage tank
Check the liquid tank frequently. Filling if necessary.

Removal of clutch master cylinder, clutch cylinder
1. Use the No. 16 open-end wrench to remove the hose connecting
bleed bolt, use the cloth to cover the oil outlet of auxiliary pump
to avoid the splash of 0brake fluid; step on the clutch pedal for
several times to drain the clutch.
Cautions for installation of clutch operation device:
1. Installation of clutch hard pipe : Check the hard pipe for
deformation, check to see whether the curling at the port of
connection pipe is complete and without damage, if there is no
problem after confirmation, it can be installed and fixed in the
front wall clip and hard-tube clip.
2. Coat each rotary parts of peal with the lithium base grease.
3. Check the surface of clutch hoes, no surface cracking, oil leakage
and dog leg is allowed, use the split washer and spring clip to fix
the clutch hose on the support frame of car body.
4. Connect the joints of the general pump oil pipe and the general
2. Remove the split pin and cylinder pin connected the master
pump connecting fork to the pedal; use the No. 13 socket spanner
to remove two nuts Q32008 which is used to install the master
pump. Check the clutch master cylinder, replace the complete
master pump if the internal of master pump has the abnormal
noise and damage of leakage etc.
pump and sub pump according to the required tightening torque.
5. The air in the clutch oil path needs to be exhausted after filling
oil (except the vacuum filling): step on the clutch pedal after
fillingthe oil tank, when feeling difficult in stepping, use the
open-end wrench with specification of 11 to loosen the air bleed
plug screw to exhaust the air, then tighten the plug screw,
repeat the operation for several times. Tighten the air bleed
plug screw of the sub pump when there is no foam in the
flowing oil liquid. Supplement the oil of the oil tank to the
level between the Max and the Min.
