Commutator Service
Clean the commutator with a coarse, lint free cloth. Do
not use emery cloth.
If the commutator is badly worn or grooved, turn it
down on a lathe or replace the armature.
Starter Reassembly
1. Place the wave washer, followed by the thrust
washer onto the drive sha of the armature. See
Figure 7-20.
Figure 7-20. Washers Installed on Armature.
Figure 7-21. Armature Installed in Starter Frame.
3. Align the holes with the spaces between the
magnets and install the drive end cap onto the
front of the frame.
4. If the brush assembly is not being replaced,
position the springs and brushes within their
pockets in the carrier; move them to the retracted
position, and install carton staples to retain them.
See Figure 7-22. Replacement brushes come
pre-assembled in the carrier housing, retained
with two carton staples.

from the positive (+) brush lead stud.
2. Remove the thru bolts and captured hex nuts.
3. Remove the commutator end cap, then pull the
brush carrier assembly out of the frame. See
Figure 7-19.
2. Insert the armature into the starter frame. The
magnets will hold it in place. See Figure 7-21.
