CLUTCH DISC, CLUTCH COVER AND FLYWHEEL
INSPECTION AND ADJUSTMENT AFTER REMOVAL
Clutch Disc
●Measure circumferential runout relative to the clutch disc center
spline. If it is outside the specification, replace the clutch disc.
●Measure clutch disc spline and input shaft spline backlash at the
circumference of the disc. If outside the specification, replace.
●Using calipers, measure the depth to the clutch disc facing rivet
heads. If it exceeds the allowable wear limit, replace the clutch
disc.
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 a diaphragm adjusting wrench (special service tool).
●Check clutch cover thrust ring for wear or breakage. If wear or
breakage is found, replace clutch cover assembly.
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 the assembly.
Flywheel Runout
Using a dial gauge, measure runout at the flywheel clutch contact
surface. If runout is outside the specification, replace the flywheel. If
a trace of burn or discoloration is found on the surface, repair it with
sandpaper.
CAUTION:
Measure it at flywheel outer face (not on knock pin and clutch cover mounting hole). Runout limit/diameter of the area to be measured:
1.0 mm (0.039 in) or less/230 mm(9.06 in) dia.
Maximum allowable spline backlash:
1.0 mm (0.039 in)

Facing wear limit (depth to the rivet head):
0.3 mm (0.012 in)

Tolerance for diaphragm spring lever unevenness:

INSTALLATION
1. Apply recommended grease to clutch disc and input shaft splines.
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 quiver. Wipe off any grease oozing
from the parts.
2. Install clutch disc and clutch cover. Pre-tighten mounting bolts
and install clutch aligning bar.
3. Tighten clutch cover attaching bolts evenly in two steps in the
order shown in the figure.
4. Install manual transaxle.
●Refer to MT-15, "Removal and Installation" .
