    Clutch Disc

    Inspect/Replace

    • The removal and replacement of a clutch assembly can be completed while the engine is in or out of the car. The clutch assembly is mounted to the flywheel that is mounted to the rear of the crankshaft.
    • Before disassembling the clutch, make sure alignment marks are present on the pressure plate and flywheel.
    • The attaching bolts should be loosened before removing any of the bolts. With the bolts loosened, support the assembly with one hand while using the other to remove the bolts. The clutch disc will be free to fall as the pressure plate is separated from the flywheel. Keep it intact with the pressure plate.
    • The surface of the pressure plate should be inspected for signs of burning, warpage, and cracks. Any faults normally indicate that the plate should be replaced.
    • The surface of the flywheel should also be carefully inspected. Normally the flywheel surface can be resurfaced to remove any defects. The pilot bushings or bearing should also be inspected.
    • Insert the new clutch disc into the pressure plate as the pressure plate is moved to its proper location. Make sure the disc is facing the correct direction. Most are marked to indicate which side should be seated against the flywheel surface.
    • Install the pressure plate according to the alignment marks made during disassembly.
    • Install the attaching bolts, but do not tighten. Then install the clutch alignment tool through the hub of the disc and the pilot bearing. This will center the disc on the flywheel.
    • With the disc aligned, tighten the attaching bolts according to the procedures outlined in the service manual.
