DISASSEMBLY, INSPECTION
AND REPAIR
1. See Figure 5-15. Lift rubber boot (1). Remove field wire
nut with washer (2) (metric) to detach field wire (3).
2. See Figure 5-16. Remove both thru-bolts (1, 3).
3. Remove both end cover screws with O-rings (2) and end
cover (4).
4. See Figure 5-17. Use a wire hook to pull upward on
brush springs (3), and lift brushes out of holder (2).
Remove brush holder.
5. Check brush length. Replace all four brushes if length of
any one brush is less than 0.433 in. (11.0 mm).
NOTE
Brushes not available separately. Purchase a new field frame
(1) and brush holder (2) to replace brushes.
6. Remove armature (4) and field frame (1).
7. Place armature in lathe or truing stand and check com-
mutator runout and diameter.
a. Commutators with more than 0.016 in. (0.406 mm)
of runout should be replaced or machined on a
lathe.
b. Replace commutators when diameter is less than
1.141 in. (28.981 mm)
c. Check armature bearings. Replace if necessary.
CAUTION
Do not use sandpaper or emery cloth to remove burrs on
commutator. Otherwise, abrasive grit may remain on
commutator segments; this could lead to excessive
brush wear. Use only the recommended crocus cloth.
8. Check depth of mica on commutator. If undercut is less
than 0.008 in. (0.203 mm), use an undercutting machine
to undercut the mica to 1/32 in. (0.794 mm) deep. The
slots should then be cleaned to remove any dirt or cop-
per dust.
See Figure 5-18. If an undercutting machine is not avail-
able, undercutting can be done satisfactorily using a thin
hacksaw blade. After undercutting, lightly sand the com-
mutator with crocus cloth to remove any burrs.
9. See Figure 5-19. Check for SHORTED ARMATURE with
a growler.
a. Place armature on growler (1).
b. Hold a thin steel strip (2) (hacksaw blade) against
armature core and slowly turn armature.
c. A shorted armature will cause the steel strip to
vibrate and be attracted to the core. Replace
shorted armatures.
