Starter Bearing: Testing and Inspection

1. Inspect the self-lubricating bronze/iron armature bushings in the drive housing and brush end plate and bushing. Replace bushings whenever excessive starter motor armature shaft side-play is evident (maximum allowable 0.2 mm (0.008 inch)).
2. Replace bushings if worn or scored. Check the output shaft for wear if the bushings are excessively scored or worn. Service or replace output shaft as necessary.
