    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 existing manual transmission engine flywheel must be installed 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.
    • DO NOT remove the propeller shaft hub or flexplate from the automatic transmission engine flywheel. The flywheel, propeller shaft hub, and flexplate are balanced as an assembly. If service is required, the entire flywheel assembly should be replaced.
  1. Mark or scribe the end of the crankshaft and the manual transmission flywheel. Refer to Engine Balancing .
