Bearing Removal
1. Place the wedge attachment tool (CCI P/N 1012812) between the bearing and the armature. Make sure
the wedge attachment tool is supporting the inner race of the bearing. If a press is not available, secure
a bearing puller (CCI P/N 1012811) to the wedge attachment tool and pull the bearing off of the end of
the armature shaft. Support the armature so that it will not drop when the bearing is removed
(Figure 12-9, Page 12-6).
2. Discard the bearings.
3. Slide the bearing retainer (32) off of the output end of the shaft
(Figure 12-7, Page 12-5)
.
Field Coil Removal
1. Remove the retaining nut from each field coil terminal and slide the insulator out of the slots in the hous-
ing. Remove the four pole piece screws from the housing. Remove the four pole pieces from inside the
housing. Remove the field coils from the inside of the housing
(Figure 12-10, Page 12-7)
.
See following
NOTE.
NOTE:
Do not remove the insulators or the field coils unless an electrical test indicates that it is necessary
(Figure 12-10, Page 12-7)
.
See Test Procedure 8, Section 11, Page 11-15.
Visual Inspection of Armature
Obvious defects can be seen by examining the armature. If an armature has frayed or charred insulation, bro-
ken wires or thrown solder, it is obvious without testing that it should be replaced. Faults seen during the visual
inspection can aid in diagnosing the original cause of the failure. Items to look for are listed below.
•
Burned, charred, or cracked insulation
•
Improperly cured varnish
•
Thrown solder
