Starter - MITSUBISHI: Overhaul: Commutator
Inspect commutator for roughness, grooves, burns, pitting and out-of-round. If necessary, sand lightly with 500-600 grit sandpaper. If mica insulator undercut is less than .008" (.20), undercut to .020-.031" (.50-.80 mm). Replace armature if commutator diameter is less than specified. See COMMUTATOR MINIMUM DIAMETER table.
