Starter Armature: Initial Inspection and Diagnostic Overview
CAUTION: Do not wash the starter drive because the solvent will wash out the lubricant causing starter drive to slip. Use a brush or compressed air to
clean the starter drive, armature, brush, and gear assemblies, drive end housing, pole pieces and planet gears. Wash all other parts In solvent and dry.
1. Inspect starter motor armature windings for broken or burned insulation and unwelded or open connections.
2. Check starter motor armature for open circuits, shorts and grounds. Check for pole rub or rub on magnetic shunts.
3. Check commutator for runout. Inspect armature shaft and two bushings for scoring and excessive wear with Dial Indicator D87L-4201-A and
Magnetic Base D87P-4201-B or equivalent. If commutator is rough, or more than 0.12 mm (0.005 inch) out of round, it must be replaced.
