Clutch
General Description
Clutch ConstructionS7RS0B5301001
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 four torsional coil springs, is positione d on the transaxle input shaft with an involute spline fit.
The clutch cover is secured to the flywheel, and carries the diaphragm spring in such a way that the peripheral edge
part of the spring pushes on the pressure plate against the flywheel (with the disc in between), when the clutch release
bearing is held back. This is the engaged condition of the clutch.
Depressing the clutch pedal c auses the release bearing to advance and pushes on the tips of the tapered fingers of
the diaphragm spring. When this happens, the diaphragm sp ring pulls the pressure plate away from the flywheel,
thereby interrupting the flow of drive from flywheel through clutch disc to transaxle input shaft. Clutch fluid is supplied
from brake fluid reservoir. Clutch fluid level can be checked by brake fluid level of brake fluid reservoir.

Repair Instructions
Clutch Pedal InspectionS7RS0B5306001
Cylinder Push Rod Play “A”1) Press clutch pedal (1) gradually with finger, stop when slight increase of resistance is felt and
measure how much pedal has moved (push rod
play) as represented by “A” as shown.
Push rod play
“A”: Max. 3 mm (0.12 in.)
2) If “A” is not within specification, replace master cylinder (3) or pedal arm (2). Clutch Pedal Free Travel “B”
1) Depress clutch pedal (1), stop the moment clutch resistance is felt, and measure how much pedal has
moved (clutch pedal free travel) as represented by
“B” in figure.
Clutch pedal free travel
“B”
: 2 – 8 mm (0.08 – 0.31 in.)
2) If “B” is not within specification, check pedal arm (2) and master cylinder (3) and replace defective part.

Clutch Release Margin “C”1) Pull up parking brake fully and block wheels.
2) Start engine and keep engine at idle with neutral gear position.
3) Without clutch pedal (1) dep ressed, slightly push the
shift lever to re verse position until transaxle emits
gear contact noise. Do not shift the lever to reverse
position.
4) With emitting gear contact noise, be slow to depress clutch pedal (1), and at gear contact noise died
position (release point) stop depressing.
5) Measure distance between release point (4) and full stroke point (5) on clutch pedal (1) which is shown by
“C” in figure.
Clutch release margin
“C”: 25 – 55 mm (0.98 – 2.17 in.)
6) If “C” is not within specificat ion, it is possible that air
is trapped in this system. If suspected so, bleed air
referring to “Air Bleeding of Clutch System”. Upon
completion of above inspection, start engine and
check clutch for proper operation.
Clutch Fluid Level InspectionS7RS0B5306002
Refer to “Brake Fluid Level Inspection in Section 4A”.
Clutch fluid specification
: Refer to reservoir cap.
Air Bleeding of Clutch SystemS7RS0B5306003
CAUTION!
Brake fluid is extremely damaging to paint. If
fluid should accidentally touch painted
surface, immediately wipe fluid from paint
and clean painted surface.

Bleeding operation is necessary to remove air whenever
it entered hydraulic clutch system.
1) Fill master cylinder reservoir with brake fluid and keep at least one-half full of fluid during bleeding
operation.
Brake Fluid
Refer to reservoir cap
2) Remove bleeder plug cap from clutch operating cylinder (3). Attach a vinyl tube (1) to bleeder plug
(4), and insert the other end into container (2).

3) Depress clutch pedal several times, and then release clutch pedal, push snap ring (2) and pull pipe
connector (1) one notch.
4) When fluid pressure in cylinder is almost depleted, push pipe connector.
5) Repeat this operation until there are no more air bubbles in hydraulic line.
6) When bubbles stop, depress and hold clutch pedal, push pipe connector, and pull snap ring.
7) Then attach bleeder plug cap.
8) After completing bleeding operation, apply fluid pressure to pipe line and check for leakage.
9) Replenish fluid into reserv oir up to specified level.
10) Check clutch pedal for sponginess. If found spongy, repeat entire procedure of bleeding.Clutch Pedal Position (CPP) Switch Removal
