CAUTION:

• Never reuse CSC (Concentric Slave Cylinder). Because CSC slides back to the original position

every time when removing transaxle assembly. At this timing, dust on the sliding parts may damage
a seal of CSC and may cause clutch fluid leakage.

• Never disassemble CSC.
• Keep painted surface on the body or other parts free of clutch fluid. If it spills, wipe up immediately

and wash the affected area with water.

REMOVAL

1.

Remove transaxle assembly from the engine. Refer to 

TM-25, "Removal and Installation"

.

2.

Remove CSC mounting bolts and then remove CSC from clutch housing.

INSTALLATION

1.

Install CSC to clutch housing and then tighten CSC mounting bolts to the specified torque.

CAUTION:

• Never reuse CSC.
• Never insert and operate CSC because piston and stopper of CSC components may fall off.

2.

Install transaxle assembly to the engine. Refer to 

TM-25, "Removal and Installation"

.

CAUTION:

• Never reuse CSC (Concentric Slave Cylinder). Because CSC slides back to the original position

every time when removing transaxle assembly. At this timing, dust on the sliding parts may damage
a seal of CSC and may cause clutch fluid leakage. Refer to 

CL-17, "Removal and Installation"

.

• Never bring any grease to the clutch disc facing, pressure plate surface and flywheel surface.
• When installing, be careful that grease applied to input shaft does not adhere to clutch disc.
• Never clean clutch disc using solvent.

REMOVAL

1.

Remove transaxle assembly from the engine. Refer to 

TM-25, "Removal and Installation"

.

2.

Remove clutch cover mounting bolts while holding clutch cover, using a power tool [Commercial service
tool].

CAUTION:

Never drop clutch disc.

3.

Remove clutch cover and clutch disc.

CAUTION:

Never drop clutch disc.

INSTALLATION

1.

Clean clutch disc and input shaft splines to remove grease and powder arisen from abrasion.

2.

Apply recommended grease to clutch disc and input shaft splines.

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 judder. And if it adheres to seal of
CSC, it cause clutch fluid leakage. wipe out excess grease. wipe out any grease oozing from the
parts.

Inspection

INFOID:0000000009949683

INSPECTION AFTER REMOVAL

CLUTCH DISC

• Measure circumferential runout relative to clutch disc center spline.

If it is outside the specification, replace clutch disc.

• Measure backlash to clutch disc spline and main drive gear spline

at the circumference of clutch disc. If it is outside the specification,
replace clutch disc.

• Measure the depth “A” to clutch disc facing rivet heads, using a

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

CLUTCH COVER

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

NOTE:
• Worn thrust ring will generate a beating noise when tapped at the rivet with a hammer.
• 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.
