CAUTION:

• If transmission assembly is removed from the vehicle, always replace CSC (Concentric Slave Cylinder) body and CSC tube.

Return CSC body insert to original position to remove transmission assembly. Dust on clutch disc sliding parts may damage
seal of CSC body and may cause clutch fluid leakage.

• Be careful not to bring any grease to the clutch disc facing, pressure plate surface and flywheel surface.

• When installing, be careful that grease applied to main drive gear does not adhere to clutch disc.

• Do not clean in solvent on clutch disc.

• If flywheel is removed, align dowel pin with the smallest hole of flywheel. Refer to

INSPECTION AFTER REMOVAL

CLUTCH DISC

• Measure circumferential runout relative to clutch disc center spline.

If it is outside the specification, replace clutch disc and clutch cover
as a set.

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

at the circumference of clutch disc. If outside the specification,
replace clutch disc and clutch cover as a set.

• Measure the depth to clutch disc facing rivet heads using calipers.

If it exceeds the allowable wear limit, replace clutch disc and clutch
cover as a set.

CLUTCH COVER

Check diaphragm spring lever claws for unevenness with the lever
still on the vehicle. If they exceed the tolerance, adjust lever height
using the diaphragm adjusting wrench [SST: ST20050240 (

)].

• Check clutch cover thrust ring for wear or breakage. If wear or

breakage is found, replace clutch disc and clutch cover as a set.
