Do not use a lifting device with a capacity of less than 215 pounds (98 kg) when
lifting adapter. Failure to observe this warning may result In serious Injury or
death to personnel.
Attach a suitable lifting device with a 215 pound (98 kg) capacity to machining adapter (25) (see Figure
5-4). Then remove hexagonal head screws (26, Figure 5-1) and lockwashers (27) to remove the adapter
Do not apply any force to the generator fan for lifting or rotating the generator
rotor. Disregarding these Instructions may cause Injury to personnel or
To avoid personnel Injury or equipment damage when lifting the generator rotor,
use a lifting device rated for a minimum 4,000 pounds (1800 kg).
Special care should be used In rotor assembly removal, or winding damage could
Using D-511856 rotor lifting fixture and a suitable hoist, carefully remove the rotor assembly (15, Figure
5-1) as follows:
(a) Refer to Figure 5-5. Install flange assembly (1) on rotor assembly (15, Figure 5-1). Secure with six
or more hexagon head screws (20), torqued to 150 pound-feet (230 newton-meters).
(b) Slide lift assembly (2, Figure 5-5) onto flange assembly (1).
(c) Attach pin (3) to flange assembly (1).
(d) Select lifting plug location closest to center of gravity of rotor assembly.
(e) Carefully remove rotor assembly and rest it on a suitable working surface.
