3. Remove through-bolts and separate drive end
housing from motor frame. Remove housing seal
assembly from drive. Remove drive and gear
assembly from drive end housing.

Remove stop ring and retainer from driveshaft,
then remove drive assembly from shaft. Push
C-ring off driveshaft, and separate gear assembly

Cleaning and Inspection
CAUTION: Do not wash the drive because the
solvent will wash out the lubricant causing drive to
slip. Use a brush or compressed air to clean the
drive, armature, brush, and gear assemblies, drive
end housing, pole pieces and planet gears. Wash
all other parts in solvent and dry.
1.
Inspect armature windings for broken or burned
insulation and unwelded or open connections.
2.
Check armature for open circuits, shorts and
grounds. Check for pole rub or rub on magnetic
shunts.
3.
Check commutator for runout. Inspect armature
shaft and two bearings for scoring and excessive
wear with Dial Indicator TOOL-4201-C or
equivalent. If commutator is rough, or more than
0.12mm (.005 inch) out of round, it must be
replaced.
5. Remove brush plate screws and brush end plate
from motor frame. Remove brush assembly and
push armature out of frame.
