Removal and Installation

Removal and Installation

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.

• Do not disassemble CSC.

• Keep painted surface on the body or other parts free of clutch fluid. If clutch fluid spills, wipe up immediately and wash the affected area with water.

REMOVAL

Remove engine and transaxle assembly. Refer to Removal and Installation.

Remove CSC bolts, then remove the CSC from transaxle assembly.

INSTALLATION

Install CSC to transaxle assembly, then tighten CSC bolts to the specified torque.

CAUTION:

• Do not reuse CSC.

• Do not install then operate CSC immediately, the piston and stopper of CSC components may fall off.

Install engine and transaxle assembly in the reverse order of removal. Refer to Removal and Installation.

Removal and Installation

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 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

Remove engine and transaxle assembly. Refer to Removal and Installation.

Loosen clutch cover bolts evenly while holding clutch cover.

Remove clutch cover and clutch disc.

CAUTION:

Do not drop clutch disc.

INSTALLATION

Clean clutch disc and input shaft splines to remove grease and dust caused by abrasion.

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.

Install clutch disc, using a suitable tool (A).

Install clutch cover, and then temporarily tighten clutch cover bolts.

Tighten clutch cover bolts to the specified torque evenly in two steps in the numerical order as shown.

Install engine and transaxle assembly. Refer to Removal and Installation.

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

Runout limit/diameter of the area to be measured

: Refer to Clutch Disc.

Maximum allowable spline backlash (at outer edge of disc)

: Refer to Clutch Disc.

Facing wear limit (depth to the rivet head) “A”

: Refer to 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.
