10. INSPECT BRUSH LENGTH
a. Using vernier calipers, measure the brush length.
Standard length: 15.0 mm (0.591 in. )
Minimum length: 9.0 mm (0.354 in. )
If the length is less than minimum, replace the brush holder and field frame.
11. INSPECT BRUSH SPRING LOAD
a. Using a pull scale, measure the spring load by pulling the spring from the brush until they are separated.
Standard spring installed load: 21.5 to 27.5 N ( 2.2 to 2.8 kgf, 4.8 to 6.2 lbf )
Minimum installed load: 12.7 N (1.3 kgf, 2.9 lbf )
If the installed load is less than minimum, replace the brush springs.
12. INSPECT BRUSH HOLDER INSULATION
a. 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.
13. INSPECT GEAR TEETH
a. Check the gear teeth on the pinion gear, idle gear and the clutch assembly for wear or damage.
If any damage is found, replace the gear or clutch assembly, and also check the drive plate ring gear for wear or damage.
