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 12-11, Page 12-8).
