Fig.10 Starter Motor Shim:

1. If the complaint is similar to Condition 1, the starter motor must be moved toward starter ring gear by removing shims from both starter mounting pads on engine block (Fig. 10). Refer to Starter Motor for removal/installation.

NOTE: The shim thickness is 0.381 mm (0.015 in.). These shims may be stacked if additional thickness is required.

2. If complaint is similar to Condition 2, starter motor must be moved away from starter ring gear. This is done by installing shim(s) across both starter mounting pads on engine block. More than one shim may be required. Refer to Starter Motor for removal/installation.

NOTE: This is a condition that will generally cause broken starter (flywheel/torque converter drive plate) ring gear teeth or broken starter motor housings.
