Clutch
General Description
Clutch (Hydraulic Type) ConstructionS6RW0D5301001
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 positioned 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 (incorporated in clutch operating cylinder) is held back. This is the engaged condition of the clutch.
Depressing the clutch pedal causes the release bearing (incorporated in clutch operating cylinder) 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
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 InspectionS6RW0D5306001
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 the 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) depressed, slightly push the
shift lever to reverse 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 the figure.
Clutch release margin
“c”: 25 – 55 mm (0.98 – 2.17 in.)6) If “c” is not within specification, 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 InspectionS6RW0D5306002
Refer to “Brake Fluid Level Inspection in Section 4A”.
Clutch fluid specification
: Refer to the reservoir cap of the brake master
cylinder.
Air Bleeding of Clutch SystemS6RW0D5306003
CAUTION!
When operating the pedal stroke for air
bleeding of clutch system, after releasing the
clutch pedal, be sure to wait 1 second or
more before depressing it again. Otherwise,
the oil seal of operating cylinder will be
damaged, resulting in oil leakage.
Bleed air from clutch system.
Refer to “Air Bleeding of Brake System in Section 4A”.

m, 11.5 lb-ft)4) Remount transaxle assembly referring to “Manual
Transaxle Unit Dismounting and Remounting in
Section 5B”.
5) Bleed air from system and check clutch pedal free
travel. Refer to “Air Bleeding of Clutch System” and
“Clutch Pedal Inspection”.
Clutch Operating Cylinder Assembly InspectionS6RW0D5306013
Check clutch fluid leakage, spring for damage and
bearing for smooth rotation. If malfunction is found,
replace clutch operating cylinder assembly.
