Electrical System and Components
Retaining Ring Installation
1. Position the retaining ring in the groove in one of
the inner halves. Assemble the other half over
the top and slide on the outer collar.
2. Be certain the drive components are installed in
correct sequence onto the armature shaft.
3. Slip the tool over the end of the armature shaft,
so the retaining ring inside is resting on the end
of the shaft. Hold the tool with one hand, exerting
slight pressure toward the starter. Tap the top of
the tool with a hammer until you feel the
retaining ring snap into the groove. Disassemble
and remove the tool.
4. Squeeze the retaining ring with a pliers to
compress it into the groove.
5. Assemble the inner halves, with the larger
cavity, around the spring retainer (see Figure
8-14). Slide the collar over them and thread the
center screw in until resistance is felt.
Figure 8-14. Assembling Larger Inner Half Around
Spring Retainer.
6. Hold the base of the tool with a 1 1/8" wrench
and turn the center screw clockwise with a 1/2"
or 13 mm wrench to draw the spring retainer up
around the retaining ring. Stop turning when
resistance increases. Disassemble and remove the
tool.
7. Reinstall the dust cover.
Starter Disassembly
1. Remove the drive components following the
instructions for servicing the drive.
2. Locate the small raised line on the edge of the
drive end cap. On starters with Style "A"
commutator end caps, it will be aligned with a
premarked line on the starter frame. The frame is
not premarked on starters with Style "B" end
caps. Place a piece of masking tape on the frame
and mark a line on the tape in line with the
raised line on the end cap. See Figure 8-17.
3. Remove the thru bolts.
4. Remove the commutator end cap with brushes
and brush springs (Style "A"). Style "B" end caps
remove as a separate piece with the brushes and
carrier remaining in the frame.
5. Remove the drive end cap.
6. Remove the armature and thrust washer (if so
equipped) from inside the starter frame.
7. Remove the brush/carrier assembly from the
frame (Style "B" end cap starters).
Style "A" End Cap Brush Replacement
1. Remove the brush springs from the pockets in
brush holder. See Figure 8-15.
2. Remove the self-tapping screws, negative (-)
brushes, and plastic brush holder.
3. Remove the hex flange nut and fiber washer from
the stud terminal.
Remove the stud terminal with positive (+)
brushes and plastic insulating bushing from the
end cap.
4. Reinstall the insulating bushing to the new stud
terminal with the positive brushes. Install the
stud terminal with bushing into the commutator
end cap. Secure the stud with the fiber washer
and hex flange screw.
5. Install the brush holder, new negative brushes,
and self-tapping screws.
6. Install the brush springs and brushes into the
pockets in brush holder. Make sure the
chamfered sides of brushes are away from the
brush springs.
NOTE:
Use a brush holder tool to keep the
brushes in the pockets. A brush holder
tool can easily be made from thin sheet
metal. See Figure 8-16.
