Installation Procedure
Important:
^
The flywheel does not use a locating pin for alignment and will not initially seat against the crankshaft flange or spacer, if applicable, but will be
pulled onto the crankshaft by the engine flywheel bolts. This procedure requires a three stage tightening process.
^
Certain applications (6.0L) require a spacer and longer bolts for proper flywheel position.
1. Install the spacer, if applicable, onto the rear of the crankshaft.
2. Install the flywheel and bolts to the crankshaft.
Important: Longer flywheel bolts must be used on applications using a flywheel spacer.
3. Apply threadlock GM P/N 12345382, (Canadian P/N 10953489) or equivalent to the threads of the flywheel bolts.
