CLUTCH PEDAL
FREE PLAY INSPECTION
lPress the clutch pedal by hand until certain resistance can be
felt. Using a scale, check that the free play is within the specified
range.
CLEARANCE CHECK
1. Start the engine and let it idle.
2. Apply parking brake.
3. Depress the brake pedal.
4. Fully depress clutch pedal and shift to 1st gear.
5. Release clutch pedal gradually. Stop releasing the pedal at the
point where the clutch is about to be engaged. Using a scale,
check the clearance between the clutch pedal and floor panel to
see if it is within the specified range.
NOTE:
Pedal height at clutch disengagement varies slightly from the clutch engagement point.Despite this, pedal
height at clutch engagement is commonly used for both cases in order to simplify they the inspection.
Removal and InstallationECS001WC
NOTE:
Install clutch pedal assembly and adjust the pedal height. Tighten stopper bolt to the specified torque.Pedalfreeplay :9-16mm(0.35-0.63in)

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, "
