Flywheel or Flexplate & Ring Gear


Removal & Installation

The ring gear is an integral part of the flywheel and is not replaceable. To remove the flywheel:

  1. Remove the transmission.
  3. Remove the six bolts attaching the flywheel to the crankshaft flange. Remove the flywheel.
  5. Inspect the flywheel for cracks, and inspect the ring gear for burrs or worn teeth. Replace the flywheel if any damage is apparent. Remove burrs with a mill file.
  7. If equipped with a manual transmission inspect the pilot bearing and replace if necessary.
  9. If equipped with a spacer between the crankshaft and flywheel, reinstall the spacer.
  11. Install the flywheel. The flywheel will only attach to the crankshaft in one position, as the bolt holes are unevenly spaced. Install the bolts and tighten in a criss-cross pattern. Refer to the Torque Specifications chart in the Engine Mechanical section of this manual under the Specification Charts sub-section for the proper tightening torques.
