CAUTION:
lBe careful not to damage sensor edge and rotor tooth. Before removing front or rear wheel hub,
remove wheel speed sensor to avoid sensor wiring damage. Otherwise, sensor may be deacti-
vated.
lWhen removing sensor, avoid rotating it as much as possible. Do not forcibly pull sensor harness.
lWhen installing, check sensor pick-up and mounting hole for foreign material such as iron chips.
Check no foreign material has been caught in sensor rotor. Remove any foreign material found.
Tighten mounting bolts and nuts to the specified torque.

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, "

OUTER DIAMETER OF CONNECTING ROD BOLT
lMeasure outer diameter (d) at position shown in the figure.
lWhen “d ” exceeds the limit (when it becomes thinner), replace
the bolt with a new one.
MOVEMENT AMOUNT OF FLYWHEEL (M/T MODELS)
NOTE:
lInspection for double mass flywheel only.
lDo not disassembly double mass flywheel.
Flywheel Deflection
lMeasure deflection of flywheel contact surface to the clutch with a dial gauge.
lMeasure deflection at 210 mm (8.27 in) dia.
lWhen measured value exceeds the limit, replace it with a new
one.
Movement Amount in Radial (rotation) Direction
lCheck the movement amount in the following procedure.
1. Install a bolt to clutch cover mounting hole, and place a torque wrench on the extended line of the flywheel
center line.
lTighten bolt at a force of 9.8 N·m (1kg-m, 87 in-lb) to keep it from loosening.
2. Put a mating mark on circumferences of the two flywheel
masses without applying any load (Measurement standard
points).
3. Apply a force of 9.8 N·m (1kg-m, 87 in-lb) in each direction, and
mark the movement amount on the mass on the transmission
side.
4. Measure dimensions of movement amounts A and B on circum-
ference of the flywheel on the transmission side.

FRONT WHEEL HUB AND KNUCKLEPFP:40202
On-Vehicle InspectionEDS0005R
Inspect to check that there is no excessive play, cracking, wear, or
other damage to front axle.
lTurn front wheels (left/right) and check the play.
lCheck that no nails or other foreign objects are embedded.
lRetighten all axle nuts and bolts to the specified torque.
FRONT WHEEL BEARINGS
With the vehicle raised, inspect the following.
lMove wheel hub in the axial direction by hand. Check that there is no looseness of front wheel bearings.
lRotate wheel hub and check that there is no unusual noise or other irregular conditions. If there are any
irregular conditions, replace the wheel bearing.
Removal and InstallationEDS0005S
REMOVAL
1. Remove tire. Remove brake hose lock plate from strut.
2. Remove brake caliper from steering knuckle. Hang it in a place where it will not interfere with work.
CAUTION:
Avoid depressing the brake pedal with brake caliper removed.
3. Remove ABS wheel speed sensor from steering knuckle.
CAUTION:
Do not pull on ABS wheel speed sensor harness.
