BRUSH AND BRUSH HOLDER
1. Use a vernier caliper to measure the brush length (four
brushes).
Replace the brushes as a set if one or more of the
brush lengths is less than the specified limit.
Brush Length mm (in)
Standard Limit
15 (0.59) 12 (0.47)

2. Use a circuit tester to check the brush holder
insulation.
Touch one probe to the holder plate and the other
probe to the positive brush holder.
There should be no continuity.





3. Inspect the brushes for excessive wear. If the negative brushes have excessive wear, the
entire brush holder assembly must be replaced.
If the positive brushes have excessive wear, the entire
yoke must be replaced.

OVERRUNNING CLUTCH
1. Inspect the overrunning clutch gear teeth for excessive wear and damage.
Replace the overrunning clutch if necessary.
2. Rotate the pinion clockwise. It should turn smoothly.
3. Try to rotate the pinion in the opposite direction. The pinion should lock.
