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
