11. Fasten the lifting eye and hoist hook to the rotor
flange. Carefully hoist the rotor to avoid damaging
the exciter armature or exciter field magnets. See
Figure 8-6.
12. While the rotor is suspended, remove the photo
transistor board and actuator cup. Remove the F3,
G, and AC leads from the SCR assembly. Cut off
the photo transistor board terminals to remove the
circuit board. If the photo transistor board is
reused, leave the leads as long as possible.
13. Slowly lower the rotor to a horizontal position. Set
the rotor on a wooden surface. Take care not to
damage the windings, laminations, or bearing. See
Figure 8-7.
14. Place the generator set assembly on the generator
set adapter end in order to remove the generator
set adapter and end bracket from the stator. Fasten
chains to the generator set adapter and lower to a
horizontal position. Fasten the hook to the end
bracket eye and hoist to a vertical position. See
Figure 8-8.
