DISASSEMBLY AND INSPECTION
1. See Figure 5-16. Lift rubber boot (1). Remove field wire
nut with washer (2) (metric) to detach field wire (3).
2. See Figure 5-17. Remove both thru-bolts (1, 3).
3. Remove both end cover screws with o-rings (2) and end
cover (4).
4. See Figure 5-18. 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. (0.4 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.
IMPORTANT NOTE
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 0.031 in. (0.8 mm) deep. The
slots should then be cleaned to remove any dirt or cop-
per dust.
