Flywheel: Service and Repair

Engine Flywheel Replacement

Removal Procedure

Important: For manual transmission applications, note the position and direction of the engine flywheel before removal. The flywheel does not use a locating pin for alignment. Mark or scribe the end of the crankshaft and the flywheel before component removal. The engine flywheel must be reinstalled to the original position and direction. The engine flywheel will not initially seat against the crankshaft flange, but will be pulled onto the crankshaft by the engine flywheel bolts. This procedure requires a 3-stage tightening process.




1. Remove the transmission.
2. Remove the clutch assembly (3, 4).




3. Mark or scribe the end of the crankshaft and the flywheel.




4. Remove the engine flywheel.
5. Clean and inspect the engine flywheel.
