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.
