Assembling the Starter/Generator
Electrical System: Service and Repairs
Refer to Figure 101 for this procedure.
1. Make sure that all the starter/generator components are clean before
assembly.
2. Assembly the starter/generator internal components:
A. If the bearings were removed from the rotor assembly, install new
bearings onto the rotor shaft. Make sure the new bearings are fully
pressed onto rotor shaft.
B. If the isolator was removed, lubricate a new gasket with dielectric lubricant
and install it to the isolator. Fit the isolator to the housing assembly so the
stator conductors and stator harness pass through the isolator.
C. Lubricate a new O-ring with dielectric lubricant and install it into the
groove in the housing/stator bearing bore.
D. Apply a light coating of grease to the inside of a new lip seal and install
the seal in the housing/stator.
E. Lubricate the new O-rings with dielectric lubricant and install the O-rings
into the grooves in the cover. Place the wave washer in the cover bearing
bore and fit the rotor assembly into the cover.
F. Secure the base plate of the starter/generator rotor tool to the drive side
of the starter/generator housing/stator with three 3/8–16 X 3 inch cap
screws.
G. Install the rotor tool shaft into the base plate and turn it in so the end of the
shaft prevents the rotor body from entering the housing/stator assembly.
The rotor magnets are very powerful and can cause the rotor to
shift position very rapidly during installation. Be cautious during
rotor installation to prevent component damage or personal
injury.
H. While supporting the rotor and cover assembly, slowly turn the rotor tool
shaft to allow the rotor to be drawn into the housing/stator assembly.
Once the rotor and cover assembly is fully seated in the housing/stator
assembly, remove the rotor tool base plate.
I. Secure the cover to the housing with the six flange head screws and
tighten the screws from 19 to 21 N·m (170 to 190 in−lb).
J. Make sure that rotor rotates before continuing with starter/generator
assembly.
3. Install the spring bracket (item 26).
4. Install the starter/generator pulley:
A. Apply anti-seize lubricant to the rotor shaft and fit the square key and
starter/generator pulley onto the rotor shaft.
B. Install the flat washer and cap screw (item 24) and tighten the screw
from 36 to 42 N·m (27 to 31 ft−lb)
C. Apply a high temperature medium strength thread locking compound
(Loctite 2422 or equivalent) and tighten the square head set screws (item
25) from 14 to 16 N·m (120 to 140 in−lb).
5. Install the starter/generator fan:
