INSPECTION AND ADJUSTMENT AFTER REMOVAL
Clutch Disc

Measure circumference runout relative to the clutch disc center
spline. If it is outside the specification, replace clutch disc and
clutch cover as a set.

Measure backlash for clutch disc spline and main drive shaft
spline at the circumference of the clutch disc. If it is outside the
specified range, replace clutch disc and clutch cover as a set.

Using calipers, measure the depth to the clutch disc facing rivet
heads. If it exceeds the allowable wear limit, replace clutch disc
and clutch cover as a set.
Clutch Cover
Check diaphragm spring lever claws for unevenness with the lever
still on the vehicle. If they exceed the tolerance, adjust lever height
using the diaphragm adjusting wrench.

Check clutch cover thrust ring for wear or breakage. If wear or
breakage is found, replace clutch disc and clutch cover as a set.
NOTE:

Worn thrust ring will generate a beating noise when tapped at
the rivet with a hammer.

Broken thrust ring will make a clinking sound when cover is shaken up and down.

If a trace of burn or discoloration is found on the clutch cover pressure plate to clutch disc contact surface,
repair the surface with sandpaper. If surface is damaged or distorted, replace clutch disc and clutch cover
as a set.
INSTALLATION
1. Apply recommended grease to clutch disc and main drive gear spline.
CAUTION:
Be sure to apply grease to the points specified. Otherwise, noise, poor disengagement, or damage
to the clutch may result. Excessive grease may cause slip or judder. And if it adheres to seal of
CSC body, it cause clutch fluid leakage. Wipe off excess grease. Wipe off any grease oozing from
the parts.Runout limit/diameter of the area to be measured
: 1.0 mm (0.039 in)/230 mm (9.06 in) dia.
Maximum backlash of spline
: 1.0 mm (0.039 in)
