Do not use press which contacts core windings. Press only on core laminations.
Failure to observe this caution could result in damage to the equipment.
Remove heated rotor core from oven and press onto rotor shaft until firmly seated against shoulder.
Do not allow key to project more than 0.12 inch on either side of rotor.
Insure exciter rotor is positioned so that lead holes are equal distant on each side of lead slot in
Feed field leads from generator field (18) through exciter rotor (12).
Mount exciter rotor (12) onto rotor shaft and secure with Iockwashers (11) and screws (10). Torque
screws to 60 pounds-inch.
Remove only one diode at a time (Figure 3-139 sheet 2 of 2).
Install rectifiers (13) and torque to 28 pounds-inch. Connect leads to rectifiers and solder in
accordance with established procedures.
install cable clamps (7), Iockwashers (6), and screws (5).
