C, take off pressure plate casing bolt and separate it from flywheel, and take out the used friction
plate assembly.
D .. install the new friction plate assembly, please pay attention that the end which stretches longer
than the other end of friction plate hub spline housing shall face the transmission side.
E.. rotate the sliding screw clockwise and pull out the driving bearing step by step to make it
insert into friction plate hub spline hole.
F, when you judge the driving shaft already enter the fl
yw
heel middle bearing, then lock the
sliding screw and tighten the moment 79-88ft

G, install the pressure plate on flywheel.
H, adjust the clutch pedal travel route. (idle travel 30-40mm).

2.1.4 Failure Diagnosis & Solution
phenomenon
Possible reason
solution
Oil or dirt on friction plate
Use gasoline to clean then sanding
Clutch slip
!No free stoke of clutch
Adjust
revise
Bad separation of
clutch(obvious chick sound
Use gasol.ine to clean then sanding
when shifting gears and
difficult gear shifting)
Interval of release bearing is too big
Oil or dirt on friction plate
Pedal stroke is not enough
adjustment
overload
de loading
Clutch vibration
Friction plate cracks or severely wears
Change friction plate assembly
Lack of brake fluid
Pedal inability
Master pump leakage
Add brake fluid
Change master pump leather collar
or assembly
The failure of clutch slip is hard to judge, but the following abnormal phenomenon can
be regarded as base of failure judgment:
I.The Forklift can not speed up; 2. After stepping on speed up pedal, the engine speed can not go up
3.Power disappears especially when climbing;
4. Fuel consumption increase
The above-mentioned abnormal phenomenons are usually misunderstood as engine failure. If you
fail to check the clutch slip, it will cause abrasion or block of clutch liner face, clutch cap and
flywheel
Inspection method of clutch slip:
I. fully pull up hand brake;
2. step on clutch pedal and shift to top gear
3.
Gradually step on accelerator pedal, and slowly loosen the clutch pedal. If the engine flames out, it
proves the clutch is in good working condition; if the engine does not flame out, the front clutch
slips.
