Inspect Overrunning Clutch

Inspect Overrunning Clutch

  1. Slide the overrunning clutch along the shaft.

    Replace if it does not slide smoothly.

  2. Rotate the overrunning clutch both ways.

    Does it lock in one direction and rotate smoothly in reverse? If it does not lock in either direction or locks in both directions, replace it.

  1. If the starter drive gear is worn or damaged, replace the overrunning clutch assembly. (The gear is not available separately.) Check the condition of the flywheel or torque converter ring gear if the starter drive gear teeth are damaged.

Cleaning

  1. Do not immerse parts in cleaning solvent.

    Immersing the yoke assembly and/or armature will damage the insulation wipe these parts with a cloth only.
