  3. Ensure commutator is free of burnt spots and scoring. If commutator surface is dirty, wipe with cloth. If commutator is excessively scored, use lathe to refinish commutator.
    NOTE: DO NOT use emery cloth on commutator.
  4. If depth between commutator segments is less than specification, undercut to specification. See STARTER MOTOR SPECIFICATIONS  . If armature shows signs of rubbing pole pieces, ensure pole pieces are tight. Check armature for bent shaft. If armature shaft is bent, replace armature.
