Clutch

CL-7

Remove release bearing.   

Install release bearing with suitable tolerance.

Inspection

Check whether the release bearing has crackle and wear. The release bear-
ing should run smoothly and noiselessly. Change it if necessary.

Check whether the surface of the release bushing and release fork has
wear, damage and corrosion. Change them if necessary.

Lubrication

Lubrication the fit surface and the friction surface of the bushing and fork
with recommended grease.

Warning
•Too much grease might result in damage to the clutch driven disc

Clutch Driven Disc and Pressure Plate

Clutch

CL-8

Clutch Driven Disc

Check

Check the wear of the driven disc;

The wear limit between the friction facing and rivet head: 0.3mm.

Check up the spline tooth gap and its deviation for the driven disc; 　

Check whether the driven disc has been burnt, discolored or polluted with
oil or grease. Change it if necessary.

Assembling

Apply some grease on the connecting surfaces and spring.

Note:
•Most grease might result in damage to the driven disc surface.

Clutch Pressure Plate and Flywheel

Checking and adjustment

·

Check the height and unevenness of diaphragm spring.

·

Put the feeler (T=0.2) on the space bush during checking up the height of

the diaphragm spring.

     Height of the diaphragm spring：41~43mm

·

If the height of the diaphragm spring is measure beyond the set range,

change the pressure plate surely.

·

Check the worn or damage condition for the diaphragm spring support

washer by rocking the pressure plate by listening to the vibration sound.
Judge whether there is light crackle sound by patting the rivet gently.
Change the pressure plate if necessary.

·

Check whether the pressure surface of the pressure plate is burnt or dirt-

ied. Remedy it with the emery paper.

Clutch

CL-9

·

Check whether the matching surface of the pressure plate and driven disc

has deformation or damage. Change them if necessary.

·

Adjust the unevenness of the diaphragm spring with tool.

Flywheel check

·

Check whether the working surface of the flywheel is burnt or discolored.

Remedy it with the emery paper.

Check its surface for planeness.

Clutch cover and flywheel

When assemble the clutch pressure plate and driven disc, insert the special
tool into the spline hole of the driven disc. (using for central position)

·

Tighten the fixed bolts the clutch cover. 　

·

Tighten the bolts as cross procedure shown in the figure with two steps.
