Starter Motor Noise

Starter Motor Noise Diagnosis:

To correct starter motor noise during cranking, use the following procedure:
1. Refer to Figure above to determine the problem.
2. If the complaint is similar to problem 1 or 2, correction can he achieved by proper "shimming" as follows (vehicles are produced without shims from the factory):
A. check flywheel ring gear for damage - bent flywheel, unusual wear, etc.
B. Shim starter as required:
- Start noise during cranking: remove 1 - 0.015 inch double shim or add a single 0.015 inch shim to the outer bolt.
- High pitched whine after engine starts: add 0.015 inch double shims until noise disappears (not to exceed 0.045 inch).
