Removal and Installation

INFOID:0000000009757039

CAUTION:

• Do not reuse CSC (Concentric Slave Cylinder). The CSC slides back to the original position every

time the transaxle assembly is removed. This action may allow dust or contaminants to gather on

the sliding parts and damage a seal of CSC causing clutch fluid leakage.

Refer to

CL-16, "Removal and Installation"

.

• Do not allow any grease to contact the clutch disc facing, pressure plate surface or flywheel surface.

• Do not clean clutch disc using solvent.

REMOVAL

1. Remove engine and transaxle assembly. Refer to

TM-28, "Removal and Installation"

.

2. Loosen clutch cover bolts evenly while holding clutch cover.
3. Remove clutch cover and clutch disc.

CAUTION:

Do not drop clutch disc.

INSTALLATION

1. Clean clutch disc and input shaft splines to remove grease and dust caused by abrasion.
2. Apply recommended grease to clutch disc (1) and input shaft (2)

splines area (A).

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 shudder. And if

it adheres to seal of CSC, it may cause clutch fluid leakage.

Wipe off excess grease. Wipe off any grease oozing from

the parts.

Inspection

INFOID:0000000009757040

INSPECTION AFTER REMOVAL

Clutch Disc

• Measure clutch facing runout. If it is outside the specification,

replace clutch disc.

• Measure spline backlash at outer edge of clutch disc. If it is outside

the specification, replace clutch disc.

• Measure the depth “A) to clutch disc facing rivet heads, using suit-

able tool. If it exceeds the allowable wear limit, replace clutch disc.

Clutch Cover

• Check clutch cover thrust ring for wear or damage. If wear or damage is found, replace clutch cover.

NOTE:

• Worn thrust ring will generate a beating noise when tapped at the rivet using suitable tool.

• Broken thrust ring will make a clinking sound when cover is shaken up and down.

• If a trace of burn or discoloration is found on the clutch cover pressure plate to clutch disc contact surface,

repair the surface with sandpaper. If surface is damaged or distorted, replace clutch cover.
