Removal and Installation
ECS009XR
CAUTION:
Be careful not to bring any grease into contact with the clutch disc facing, pressure plate surface, or
flywheel surface.
REMOVAL
1.
Remove instruction transaxle from the vehicle. Refer to
(RS6F51A).
2.
Loosen clutch cover mounting bolts evenly. Remove clutch cover and clutch disc.
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 facing.

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).
●
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).
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 judder. 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 instruction transaxle. Refer to
(RS6F51A).
Tolerance for diaphragm spring lever unevenness:
MODEL 240
