Removal and InstallationECS008BE
Carefully observe the following steps during clutch tube removal and installation.
●Do not spill clutch fluid onto painted surfaces. If it spills, wipe up immediately and wash the affected area
with water.
●To fix clutch hose on the bracket, position hose clasp on the
bracket locating embossment and drive the lock plate vertically
from above. Be careful not to bend or twist the hose. Do not
scratch or damage the clutch hose.
●Tighten clutch tube flare nut to the specified torque below:
●Tighten clutch hose union bolt to the specified torque:
CAUTION:
Do not reuse the copper washer.
●After installation, bleed the clutch tube.

Removal and InstallationECS008BF
REMOVAL
1. Remove manual transaxle from the vehicle.
●Refer to MT-15, "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 REMOVAL
●If release bearing is seized, damaged, not properly centered or
does not rotate smoothly, replace it.
●If contact surface of the withdrawal lever is excessively worn,
replace it.
●If dust cover is cracked, replace it.
INSTALLATION
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.
●Be 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.
●Evenly apply a 1-mm thick coating of recommended grease to withdrawal lever and holder spring slid-
ing surface.
●Apply 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.
●Apply 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.

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)
