Flywheel Removal

REMOVAL
1. Transmission from cylinder block.
2. Clutch from flywheel (manual transmission equipped vehicles).
3. Inspect:
^ If the ring gear is damaged, cracked or worn, replace the flywheel.
^ If the surface contacting the clutch disc is damaged or excessively worn, replace the flywheel (manual transmission equipped vehicles).
3. Mark the flywheel-to-engine position.
4. Six flywheel retaining bolts and flywheel from crankshaft.
5. Nylon clutch pilot bushing from crankshaft.
6. Clean the grease and dirt from flywheel outer surfaces using suitable solvent.


INSTALLATION

2. Apply GM P/N 12345493 or equivalent, to the flywheel retaining bolt threads.
