Starter Motor: Service and Repair

2. Disconnect cable from starter motor terminal.

Shims are available in .015 inch and .045 inch sizes, with .045 inch being the nominal design shim dimension. If noisy starter engagement is observed, shims should be removed or installed, as needed to correct the problem. However, the total shim pack thickness cannot exceed .090 inch.
