2. Remove the 2 screws and washers.
2. Remove the brush plate and brushes. Measure the brush
length and replace if worn past the service limit.
Brush Length Service Limit
5 mm (0.20“)
3. Inspect the surface of the commutator for wear or
discoloration. See Armature Test.
4. Be sure that the terminal bolt insulation washer is properly
seated in the housing and the tab on the brush plate engages
the notch in the brush plate housing.
3. Remove magnet housing while holding the armature and
brush holder section together.
Starter Brush Inspection / Replacement
1. Using an Ohm meter, measure the resistance between the
cable terminal and the insulated brush. The reading should
be .3 ohms or less. Measure the resistance between the cable
terminal and brush housing. Make sure the brush is not
touching the case. The reading should be infinite (no reading).
Armature Test
1. Inspect surface of commutator. Replace if excessively worn
or damaged.
2. Using a digital multi-tester, measure the resistance between
each of the commutator segments. The reading should be
.3 ohms or less.
