Removal and Installation

CAUTION:

• Do not reuse CSC (concentric slave cylinder). CSC slides back to the original position every time when removing transaxle assembly. At this time, dust on the sliding parts may damage the seal of CSC and may cause clutch fluid leakage.
• Do not allow any grease to contact the clutch disc facing, pressure plate surface and flywheel surface.
• Do not clean clutch disc using solvent.

REMOVAL

1. Remove transaxle assembly. Refer to TM, "Removal and Installation".
2. Loosen clutch cover bolts evenly. Then remove clutch cover and 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 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 shudder. If grease adheres to seal of CSC, it may cause clutch fluid leakage. Wipe off excess grease. Wipe off any grease oozing from the parts.

3. Install clutch disc, using suitable tool (A).
4. Install clutch cover and then temporarily tighten clutch cover bolts.
5. Tighten clutch cover bolts to the specified torque evenly in two steps in the numerical order as shown.
6. Install transaxle assembly. Refer to TM, "Removal and Installation".

Clutch Disc

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

Runout limit/diameter of the area to be measured : Refer to CL, "Clutch Disc".

• Measure spline backlash at outer edge of clutch disc. If it is outside the specification, replace clutch disc.

Maximum allowable spline backlash (at outer edge of disc) : Refer to CL, "Clutch Disc".

• Measure the depth (A) to clutch disc facing rivet heads, using suitable tool. If it exceeds the allowable wear limit, replace clutch disc.

Facing wear limit (depth to the rivet head) (A) : Refer to CL, "Clutch Disc".

Clutch Cover

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