PROCEDURE
1. Remove the spark plug wire.
2. Open the brush holder assembly
cover. Squeeze the 2 tabs and
depress the cover at the top with a
screw driver or your fingernail. The
cover will drop open on its bottom
hinge.
3. With the 1/4” nut driver, remove the
2 screws that hold the brush holder
assembly in place.
4. With the needle nose pliers, gently
remove the two white wires.
Note: Lead 202A is inboard. Lead 201A
is outboard.
5. To change the brushes, use the slot
head screw driver to pop off the
plastic retainer on the back of the
brush holder assembly.
6. Remove the old brush assemblies
and insert the new ones. One corner
of the terminal clip is beveled so that
the brush can go in only one way.
7. Snap the plastic retainer back onto
the brush holder. The brushes may
need some repositioning; wiggle
them slightly to help them seat prop-
erly.
