For Style "A" Commutator End Caps:
4. Install the brush holder tool to keep the brushes
in the pockets of the commutator end cap.
5. Align the match marks on the commutator end
cap and starter frame. Hold the drive end and
commutator end caps firmly to the starter frame.
Remove the brush holder tool.
For Style "B" Commutator End Caps:
4. If the brush assembly is not being replaced,
position the brushes in their pockets in the
carrier, move them to the retracted position, and
install carton staples to retain them. See Figure
8-18.
5. Align the terminal stud block with the notch in
the starter frame and slide the brush/carrier
assembly into the frame. The commutator will
push the carton staples out as the brush
assembly is inserted. Position the end cap over
the brush assembly, so the holes for the thru
bolts are aligned with those in the brush carrier.

Style "B" End Cap Brush Replacement
Starters with Style "B" end caps have the brushes in a
plastic carrier housing, separate from the end cap.
Replacement brushes come preassembled in the
carrier housing, retained with two carton staples.
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 thrust washer (if so equipped) over the
drive shaft of the armature.
2. Insert the armature into the starter frame. Make
sure the magnets are closer to the drive shaft end
of armature. The magnets will hold the armature
inside the frame.
3. Install the drive end cap over the drive shaft.
Make sure the match marks on the end cap and
starter frame are aligned. See Figure 8-17.

6. Install the thru bolts and tighten securely.
7. Lubricate the drive shaft with Kohler bendix
starter drive lubricant (see Section 2). Install the
drive components following the instructions for
servicing the drive.
