REMOVAL
1) Remove rear axle shaft. Refer to REAR AXLE SHAFT RE-
MOVAL in Section 3E.
2) In order to remove sensor rotor from retainer ring, grind with a
grinder one part of the sensor rotor as illustrated till it becomes
thin.
CAUTION:

Cover vinyl sheet or the like over wheel bearing so that
fine grains from grinding will not enter there.

Be careful not to go so far as to grind the retainer ring.
3) Break with a chisel the thin ground sensor rotor, and it can be re-
moved.
INSTALLATION
1) Press-fit sensor rotor as shown.
NOTE:
Use care not to cause any damage to outside of retainer
ring.
2) Install rear axle shaft. Refer to REAR AXLE SHAFT INSTALLA-
TION in Section 3E.

7C1-2 CLUTCH
The clutch is a diaphragm-spring clutch of a dry single
disc type. The diaphragm spring is of a tapering-finger
type, which is a solid ring in the outer diameter part,
with a series of tapered fingers pointing inward.
The disc, carrying torsional coil springs, is positioned
on the transmission input shaft with an involute spline
fit.
The clutch cover is secured to the flywheel, and car-
ries the diaphragm spring in such a way that the pe-
ripheral edge part of the spring pushes on the pres-
sure plate against the flywheel (with the disc in be-
tween), when the clutch release bearing is held back.
This is the engaged condition of the clutch.Depressing the clutch pedal causes the release bear-
ing to advance and pushes on the tips of the tapered
fingers of the diaphragm spring. When this happens,
the diaphragm spring pulls the pressure plate away
from the flywheel, thereby interrupting the flow of
drive from flywheel through clutch disc to transmis-
sion input shaft.

INSPECTION
Input Shaft Bearing and Release Bearing
Check bearing for smooth rotation and replace it if abnormality is
found.
Clutch Disc
Measure depth of rivet head depression, i.e. distance between rivet
head and facing surface. If depression is found to have reached
service limit at any of holes, replace disc assembly.
Rivet head depth
Standard: 1.6 mm (0.06 in.)
Service limit: 0.5 mm (0.02 in.)
Clutch Cover
1) Check diaphragm spring for abnormal wear or damage.
2) Inspect pressure plate for wear or heat spots.
3) If abnormality is found, replace it as assembly. Do not disas-
semble it into diaphragm and pressure plate.
Flywheel
Check surface contacting clutch disc for abnormal wear or heat
spots. Replace or repair as required.
