REMOVAL
1. Remove manual transaxle from the vehicle. Refer toMT-16, "Removal and Installation".
2. Remove release bearing, holder spring, and withdrawal lever from inside the clutch housing.
3. Remove dust cover.
4. Remove retainer spring from the withdrawal lever.
INSPECTION AFTER REMOVEL
lIf release bearing is seized, damaged, not properly centered or
does not rotate smoothly, replace it.
lIf contact surface of the withdrawal lever is excessively worn,
replace it.
lIf dust cover is cracked, replace it.
INSTALLATION
CAUTION:
lBe 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. Wipe off any grease oozing
from the parts.
lBe careful not to bring any grease into contact with the clutch disk facing, pressure plate surface,
or flywheel surface.

CLUTCH RELEASE MECHANISM
1. Following the instructions below, apply grease to the specified points.
CAUTION:
Wipe off any old grease, debris, or powdery residue left on the grease applying surfaces.
lEvenly apply a 1-mm thick coating of recommended grease to withdrawal lever and holder spring slid-
ing surface.
lApply recommended grease to withdrawal lever ball pin contact surface and inner slots of the release
bearing. The grease surface should be level with the surrounding area.
lApply a thin coat of recommended grease evenly to the release bearing sliding surface. Install release
bearing. Wipe off any excess grease that oozes from the parts and then remove release bearing.
2. Install in the reverse order of the removal.

REMOBAL
1. Remove manual transaxle from the vehicle. Refer toMT-16, "Removal and Installation"
2. Loosen clutch cover mounting bolts evenly. Remove clutch cover and clutch disk.
INSPECTION AND ADJUSTMENT AFTER REMOVAL
Clutch disk
lMeasure circumferential runout relative to the clutch disk center
spline. If it is outside the specification, replace the clutch disk.
lMeasure clutch disk spline and input shaft spline backlash at the
circumference of the disk. If outside the specification, replace.
lUsing calipers, measure the depth to the clutch disk facing rivet
heads. If it exceeds the allowable wear limit, replace the facing.
SCIA0329E
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:

CLUTCH DISC, CLUTCH COVER AND FLYWHEEL
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).
lCheck clutch cover thrust ring for wear or breakage. If wear or
breakage is found, replace clutch cover assembly.
NOTE:
lWorn thrust ring will generate a beating noise when tapped at
therivetwithahammer.
lBroken thrust ring will make a clinking sound when cover is
shaken up and down.
lIf a trace of burn or discoloration is found on the clutch cover pressure plate to clutch disk 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).
INSTALLATION
1. Apply recommended Grease to clutch disk 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 judder. Wipe off any grease oozing
from the parts.
2. Install clutch disk 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 toMT-16, "
