Ensure correct positioning of spacers (21), washers (20), and bolts (19)
as marked on removal.
i. Install drive discs (22) on drive hub (27) with spacers (21), washers(18) and (20), and bolts (17) and (19). Torque
bolts (17) to 28 ft-lbs (38 Nm) and bolts (19) to 35 ft-lbs (47 Nm).
j.
Install generator assembly in generator set, paragraph 4.16.2.

Shut down generator set. Allow generator to cool to ambient temperature.
Open battery access door and disconnect negative battery cable.
Remove protective cover and moveable terminal board from voltage reconnection terminal board, paragraph
2.94.2.
Disconnect two electrical connectors from bottom of control box assembly.
Tag and disconnect wires 107C and 109J from terminals 1 and 2 of power potential transformer (37, FIGURE ).
Connect resistance bridge and note readings between terminals T1 and T4, T2 and T5, T3 and T6, T7 and T0,
T8 and T0, and T9 and T0 of voltage reconnection terminal board.
All resistance readings should be as shown in TABLE 4-3.
If resistance is low, there are shorted windings, if resistance is high, stator windings are open. In either case, stator
must be replaced.
Disconnect removable grounding link on load output terminal board (17, FIGURE 2–30).
Set multimeter for ohms and connect between each coil lead and ground, in turn.
If multimeter indicates resistance on any connection, stator windings are grounded and stator must be replaced.
Connect removable grounding link on load output terminal board.
Connect wires 107C and 109J to terminals 1 and 2 of power potential transformer. Remove tags.
Connect two electrical connectors to bottom of control box assembly.
Install moveable terminal board and protective cover on voltage reconnection terminal board, paragraph 2.94.3.
Connect negative battery cable and close battery access door.
4.23.2
Removal.
a. Shut down generator set.
b. Remove generator assembly from generator set, paragraph 4.16.1.
c. Remove generator rotor assembly, paragraph 4.22.2.
d. Remove nuts (32, FIGURE 4-10), Iockwashers (33), bolts (34), and lead clamp assembly (38) from brackets (37).
e. Remove main stator setscrews (29) from housing (31).
f. Set generator housing (31) on end with end bell opening in the upright position.
Special care must be taken when feeding wires to prevent damaging
or breaking off wires.
