Before performing a Flywheel service and repair you must remove the transaxle which is attached to the engine. The removal of the clutch enables manual transaxle vehicle service. Check the ring gear for any evidence of wear as well as damage and cracking. Damage along with excessive wear and cracks on the surface where the Clutch Disc contacts will require replacement of the current Flywheel. Open several marks on the Flywheel and engine alignment and unscrew first the retaining bolts then remove the Flywheel with Crankshaft placement followed by the clutch Pilot Bearing from the Crankshaft. Use a suitable solvent to remove grease and dirt from all areas of the outer Flywheel surfaces. Install the clutch Pilot Bearing inside the Crankshaft before mounting the Flywheel while maintaining both the Flywheel-to-engine marks in alignment. Excessive sealant applied to the Flywheel retaining bolt threads should be avoided because overflown sealant may break the bolt during operation. The application of gm p/n 1234593 or equivalent on the Flywheel retaining bolt threads should be followed by installing the Flywheel retaining bolts to a torque of 95 nm (69 ft. Lbs.) for automatic transmissions and 78 nm (57 ft. Lbs.) for manual transmissions. The last process for manual-transaxle vehicles consists of attaching the clutch to the Flywheel followed by reattaching the transaxle to the engine.

Mark the flywheel-to-engine position.
