a. Removal.
(1)
Shut down generator set, paragraph 2.11.2.
(2)
Open BATTERY ACCESS door (Figure 1-2), and disconnect negative battery cable.
(3)
Remove rear housing panel. Refer to paragraph 4.7.5.
(4)
Remove bolts (1, Figure 5-9), lockwashers (2), top cover (3), and louvered covers (4) from end
bell (7).
CAUTION
The end bell supports the main rotor, thus the rotor will drop on the stator
once the end bell is removed. Prior to proceeding, bar engine by using
center bolt on harmonic balancer, TM 9-2815-259-24, until two main rotor
poles are vertical in generator stator. Having the rotor in this position will
limit the amount of drop, otherwise damage to rotor and/or stator could
occur.
(5)
Remove bolts (5) and lockwashers (6) from end bell (7).
(6)
Install two bolts (5) in back-out holes in end bell flange. Refer to Figure 5-10.
(7)
Loosen lead clamp assembly (33, Figure 5-9) clamping generator leads at side of generator
housing (11). Ensure wires F1 and F2 are free to slide in and out of generator housing.
(8) Remove end bell (7), with exciter stator (16) attached, by tightening bolts (5) evenly into back-out
holes. Remove bolts from back-out holes.
CAUTION
If bearing needs to be removed for any reason, always install new bearing.
Main bearing is easily damaged when removed from rotor shaft . Failure to
install a new bearing can cause damage to equipment.
(9) Using bearing puller, remove bearing (9) from main rotor shaft (10). Discard bearing.
