To install:

  1. Inspect the flywheel/flexplate 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.
  2.  
  3. If equipped with a manual transmission inspect the pilot bearing and replace if necessary.
  4.  
  5. If equipped with a spacer between the crankshaft and flywheel/flexplate, reinstall the spacer.
  6.  
  7. Install the flywheel/flexplate. The flywheel/flexplate 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 for the proper tightening torque values.
