1. Measure the brush length using calipers
(Figure 10-17). If the measured value is less
than the specified minimum, replace the brush
holder and field coil frame.
Brush length:
• Standard 20.5 to 21.0 mm (0.807 to 0.826 in.)
• Minimum 13.0 mm (0.511 in.)

2. Using a scale check the brush spring load
(Figure 10-18). Read the scale when the brush
spring just leaves the brush. If the measured
mounting load is out of the specified range,
replace the brush spring.
Brush spring mounting load:
• 1.9 to 3.6 kgf, 18.63 to 35.30 N (4.1 lbf to
7.9 lbf)

3. Using an ohmmeter (Figure 10-19, (1)) check
the brush holder insulation. The circuit between
the brush holder positive (+) and negative (-)
should not have electrical continuity. If
continuity is measured, repair or replace the
brush holder.
