Starter Motor Noise Test

TESTING
Before testing the starting system perform a visual inspection of the starting system components and connections. Refer to Starting System cleaning and inspection procedures.

Starter Motor Noise Diagnosis:




See the Starter Motor Noise Diagnosis chart. If the complaint is similar to Conditions 1 and 2 in the chart, correction can be made by placing shims between the starter motor and the engine block using the following procedures:

Starter Motor Shim:




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

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

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

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