13. See Figure 5-21. Check for OPEN FIELD COILS with an
ohmmeter or continuity tester. Touch one probe to the
field wire. Touch the other probe to each of the brushes
attached to the field coils. There should be continuity. If
there is no continuity at either brush, then the field coil(s)
are open and the field frame must be replaced.
14. See Figure 5-22. Test BRUSH HOLDER INSULATION
with an ohmmeter or continuity tester. Touch one probe
to holder plate. Touch the other probe to each of the pos-
itive (insulated) brush holders. There should be no conti-
nuity (infinite ohms). If there is continuity at either brush
holder, replace the brush holder assembly.
15. See Figure 5-14. Check armature bearings (8) and
replace if necessary.
16. See Figure 5-23. Remove two drive housing mounting
screws (with washers and lockwashers). Remove drive
housing from solenoid housing.
17. See Figure 5-24. Remove drive (1), idler gear (2), idler
gear bearing (3), and O-ring (4) from drive housing (O-
ring is located in drive housing groove).
ASSEMBLY
1. See Figure 5-24. Clean, inspect and lubricate drive
assembly components. Lubricate parts with high temper-
ature grease, such as LUBRIPLATE 110.
2. See Figure 5-14. When installing drive assembly compo-
nents, open end of idler bearing cage (15) faces toward
solenoid.
