Motor
Guidelines:
1. Perform the following checks before assembly:
• Using an ohmmeter, verify no electrical continuity between the
armature and commutator. Also verify no electrical continuity
between the commutator segments. Replace armature assembly
if continuity is detected.
• Inspect the commutator surface and undercuts for signs of
pitting and wear. Polish commutator with fine emery cloth or
replace armature if wear exceeds specification limit.
• Inspect the brush lengths and replace if wear exceeds
specification limit.
