Starter Assembly
Use this procedure to return the electric starter as-
sembly to service.
1.
Wipe dirt and oil from starter components using
a clean cloth;
or
blow off dirt with filtered low-
pressure compressed air.
lA CAUTION!
Oil
on
armature
will
damage
starter. Do
not
immerse bearings
in
clean-
ing
fluid. Use a
brush
dipped
in
clean en-
gine
oil
to remove
dirt
from bearings.
Avoid
getting
oil
on
brushes
or
commutator.
2.
Mount the brush springs on tabs as shown
in
Figure 6-37. Using a small screwdriver, turn the
spring counterclockwise to torque it, so the
contact loop is inside the brush holder. The
spring should be pushed down to the mounting
tab shoulder.
3.
Push the negative brush terminals over the
through-bolt holes on the brush endcap.
4.
Insert a positive brush stud into the hole, and
torque to 25-30 in-lb (2.83-3.39 N-m}.
5.
Insert a small screwdriver into the brush spring
contact loop to bend the spring back so that
each brush can be inserted into the holder. Be
sure that all brush wires are facing up.
6.
If the brushes are at least 0.430 inch
(1
0.9 mm}
long, rest the brush springs against the sides of
the brushes to keep them clear during arma-
ture installation. See Figure 6-36.

7.
Place a washer on the commutator end of the
shaft, and put the armature into the brush
endcap. Push the four brushes toward the
commutator, making sure that the springs are
correctly positioned on the brushes. Recheck
to be certain that the spring is pushed all the
way down on the mounting tab.
8.
Make sure that all brush wires are clear of the
commutator, and that uninsulated portions of
insulated wires do not touch the inside of the
housing,
or
adjacent brush boxes.
9.
Place the magnetic housing over the armature.
Hold down the armature and the end cap using
a nut driver pressed over the end of the shaft.
