9. INSPECT BRUSH LENGTH
Using a vernier caliper, measure the brush length.
Standard length: 15.5 mm (0.610 in.)
Minimum length: 10.0 mm (0.394 in.)
If the length is less than minimum, replace the brush holder and field frame.
10. INSPECT BRUSH SPRING LOAD
Take the pull scale reading the instant the brush spring separates from the brush.
Standard spring installed load: 17.6 - 23.5 N (1.8 - 2.4 kgf, 4.0 - 5.3 lbf)
Minimum spring installed load: 11.8 N (1.2 kgf, 2.6 lbf)
If the installed load is less than minimum, replace the brush springs.
11. INSPECT BRUSH HOLDER INSULATION
Using an ohmmeter, check that there is no continuity between the positive (+) and negative (-) brush holders.
If there is continuity, repair or replace the brush holder.
12. INSPECT GEAR TEETH
Check the gear teeth on the pinion gear, idler gear and clutch assembly for wear or damage.
If damaged, replace the gear or clutch assembly.
If damaged, also check the drive plate ring gear for wear or damage.
