Flywheel Installation Recommendations

  1. Keep hands clean and free of any oil and grease.
  2. Check engine and transmission seals for leaks. Replace damaged seals if necessary.
  3. Ensure that crankshaft flange is square, flat and clean.
  4. Ensure that threads in the crankshaft flange are clean. If neccesary, chase threads with a tap.
  5. Clean rust preventative coating from friction surface and mounting surface of flywheel and pressure plate.
  6. If available, use new mounting bolts for both flywheel-to-crankshaft and cover assembly-to-flywheel.
  7. It is recommended to use a thread locking compound such as Loctite® Threadlocker #262 or equivalent on all bolts.
  8. Tighten all flywheel-to-crankshaft and cover assembly-to-flywheel mounting bolts in a star pattern using manufacturers recommended torque specifications.
  9. Failure to follow manufacturer’s recommended torque specifications may damage flywheel, cover assembly and/or bolts.
  10. NEVER use a impact wrench to mount the flywheel or cover assembly! Use a torque wrench and follow manufacturer’s specifications.
  11. Other items to check include: Check crankshaft endplay, check transmission input shaft run-out and endplay, check drive shaft, U-joints, CV (constant velocity) joints and boots for worn or damaged parts.
