Starter/Generator Rework
Any rework must be performed by a qualified technician. Starter/Generator service specifications are listed in
the following table.
Starter/Generator Assembly
1. Place the field coil into the housing. The two insulators that look alike fit into the slots next to the F1 and
F2 markings on the outside of the housing. The insulator that looks different slides into the slot next to
the DF marking.
2. After the insulators are seated in the slots, install the threaded terminals through the wire connectors and
then through the insulators. Install a flat washer, lockwasher and nut onto each threaded terminal on the
outside of the housing. Tighten nuts to 47.5 in-lb (5.4 N·m)
(Figure 12-10, Page 12-6) . See following
CAUTION .
CAUT ION
• Route the field terminal wires so that they will not contact the armature.
3. Install the four pole pieces into the housing. Use the four screws to secure pole pieces to the inside of
the housing to retain the field wires. Tighten screws to 9 ft-lb (12.2 N·m) (Figure 12-10, Page 12-6) .
4. Slide the bearing retainer onto the output end of the armature shaft (33) so that it will hold the outside of
the bearing (35) only (Figure 12-7, Page 12-4) .
5. Press a new ball bearing (35) onto the output end of the armature (Figure 12-7, Page 12-4) . Press a new
ball bearing onto the commutator end of the armature shaft. See following CAUTION.
CAUT ION
• Use care while pressing new bearing onto the output end of the shaft to prevent damage to
the retainer.
• Press against the inner race of the new bearing until it is fully seated.
6. Install the output end cover (36) onto the armature. Secure the bearing retainer (32) to the cover and
tighten the screws (43) to 39 in-lb (4.4 N·m) (Figure 12-7, Page 12-4) .
