Engine Flywheel Cleaning and Inspection

  1. Clean the flywheel in solvent.
  2. Dry the flywheel with compressed air.
  3. Inspect the automatic transmission flywheel for the following conditions:
    • Damaged ring gear teeth
    • Stress cracks around the flywheel-to-crankshaft bolt hole locations
      • IMPORTANT: Do not attempt to repair the welded areas that retain the ring gear to the flywheel plate. Install a new flywheel.
    • Welded areas that retain the ring gear onto the flywheel for cracking
