2. Inspect the frame for stripped threads,
cracks, burred mating surfaces, or other
damage.
3. Inspect the stator for a loose, frayed, or

and insulation resistance. (See section 8.)
Repair or replace as necessary.
FRONT END BRACKET
INSTALLATION
1.Install two guide pins (threaded rod can be
used) into the generator side of the end
bracket mounting holes. Align the guide
pins with the holes in the generator frame
and slide the bracket onto the frame. (Figure
6-52.) Install bracket mounting cap screws.
(Figure 6-53.)
CAUTION: ON LARGE GENERATORS, A
HOIST AND LIFTING STRAP SHOULD
BE USED TO ASSIST IN THE FRONT END
BRACKET INSTALLATION .
2. Remove the two guide pins and insert the
remaining cap screws and torque to
specifications given in section 12.
MAIN ROTOR INSTALLATION
1. Grease bearing cavity and bearing with
Chevron SRI (or equivalent) grease.
2. Using a rotor lifting fixture and a suitable
hoist, carefully install the rotor assembly
into the main stator assembly through the
drive end. (Figure 6-54.) Carefully feed the
rotor leads through the front-end bracket
shaft hole as the rotor is installed.
