Manual Transaxle Oil Level CheckS6RW0D5206001
1) Lift up vehicle and check oil leakage. Repair leaky
point, if any.
2) Remove oil level / filler plug (1) and check oil
contamination and oil level is lower end of oil level /
filler plug hole (2).
If oil is excessive dirty or insufficient, replace oil or
pour specified oil up to plug hole.
3) Apply sealant to thread of level / filler plug, and then
tighten it to specified torque.

Transmission / Transaxle
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.

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”.

cylinder reservoir.
3) Pull clamp (1) of clutch master cylinder (3) and pull
clamp (5) of fluid pipe joint (4), and then disconnect
clutch fluid pipe (2).
4) Pull clamp (6) of damper (7), and then disconnect
damper (7) from clutch fluid pipe (2).Installation
Reverse removal procedure for installation noting the
following.
CAUTION!
• Do not allow fluid to get on painted
surface.
• Do not allow pipe to contact hard against
vehicle body or other parts.

• Install each clamp securely.
• After installation, check clutch pedal free travel and
bleed air from clutch system referring to “Clutch Pedal
Inspection” and “Air Bleeding of Clutch System”.
• Check fluid leakage.
• Add fluid to MAX level of reservoir.
Clutch Fluid Pipe InspectionS6RW0D5306006
Check pipe (1) for damage, dirt and leak. Replace if
check result is not satisfactory.
