Starter Gear Problems

  1. If using an aftermarket starter and starter engagement problems occur, then use a stock HD starter to check if alignment is correct. If the aftermarket starter continues to cause engagement problems, then shimming between starter and primary may be necessary.

  3. Engine may be out of time.
  4. Solenoid may be bad.
  5. Electronic ignition misfire.
  6. Worn main bearing support.

  10. Bent or worn engagement fork.
  11. Worn outer primary starter shaft support bearing.
  12. Warped or improperly made outer primary cover.
  13. Starter shaft bolt may be too tight. Tighten to HD specifications only.
