Bushings or bearings must not be cleaned
with grease dissolving agents.

PARTS INSPECTION
Armature
NOTE:
An ohmmeter may be used for the follow-
ing testing procedures, except for the one con-
cerning shorted windings in armature.
Check commutator for roughness, burnt or scored
surface. If necessary, turn commutator on a lathe,
enough to resurface only.
Check commutator for mica depth. If depth is less
than 0.20 mm (.008 in), undercut mica. Be sure
that no burrs are left and no copper dust remains
between segments after undercutting operation
is completed.
DI Engines
1. Commutator undercut 0.20 mm (.008 in)
Check commutator out of round condition with V-
shaped blocks and an indicator. If commutator out
of round is more than 0.40 mm (.016 in), commu-
tator should be turned on a lathe.
Check commutator outer diameter. If less than
27 mm (1.063 in), replace.
4-TEC Engines
Check commutator condition with an indicator. If
out of specification, replace the starter.
1. Commutator undercut 0.20 mm (.008 in)
Brush Holder
All Engines
Check brush holder for insulation using an ohm-
meter. Place one test probe on insulated brush
holder and the other test probe on brush holder
plate. If continuity is found, brush holder has to be
repaired or replaced.
WARNING
Always wear safety glasses when using com-
pressed air.
