REPAIRING THE COMMUTATOR
1. The motor must be removed from the vehicle for
this procedure. Refer to
Transmission Service
section for information on removing the motor.
2. The armature must be removed from the motor
for this procedure. Refer to
Motor Inspection-
Disassembly
section for information on taking
the motor apart.
3. Using a lathe, cut the armature just enough to
remove all grooves, depressions or ridges.
4. Measure the diameter of the commutator. If the
commutator is less than the minimum diameter
specified in
Service Limits
,
then the motor must
be replaced.
5. Thoroughly clean all copper debris from between
the commutator segments.
6. Measure the commutator undercut depth in
5-places around the commutator. If any one of the
measurements is less than the minimum undercut
depth specified in
Service Limits
, then the
commutator must be undercut.
7. While still in the lathe, smooth the commutator with
fine emery cloth.
Undercutting the commutator
1. Using a small straight cut saw blade, cut the
commutator insulation to the proper depth. Refer
to undercut depth in
Service Limits
.
2. Once all segments have been properly undercut,
mount the armature in a lathe and smooth the
commutator with fine emery cloth.
3. Inspect the armature for shorts. Refer to
Motor
Inspection
section for information on testing the
armature.
NOTE: Copper debris in the undercut area can give
a reading of a shorted armature.
