ARMY TM 9-6115-464-34 AIR FORCE 35C2-3-445-2 NAVY NAVFAC P-8-624-34 (23) Remove Iifting eye bolt and steel bar. NOTE If a steel bar is not available, carefully stand generator on end and remove rotor. (24) Remove screws (27) to remove lock plate (28), pressure plate (29), coupling disc (30), blower wheel (31) from rotor and balance assembly (25). (25) Remove screws (32) and Iockwashers (33) to remove end bell assembly (34) from stator (26). NOTE Feed leads to stator through end bell as it is removed. (26) Do not remove screws (35) or data plate (36) unless damage is present. (27) Remove gasket (37). (28) If inspection reveals damage to end bell assembly, remove screws and Iockwashers to remove exciter stator from end bell (figure 3-138). (29) If inspection reveals damage to rotor and balance assembly, disassemble as follows: NOTE Disassembly of the 400 Hz and the 50/60 Hz generator rotor and balance assembly are identical as shown in figure 3–139, even though only the 50/60 Hz rotor is shown. (a) Remove screws (1, figure 3-139) and Iockwashers (2) to disconnect electrical leads (3) and lug (4). (b) Remove screws (5), flat washers (6) and cable clamps (7). (c) Remove screws (8) and balance weights (9). NOTE Balance weights are tach welded in position. Use a chisel to break them loose. (d) Remove screws (10) and Iockwashers (11) to remove exciter rotor (12). (e) Do not remove diodes (13) unless inspection reveals damage. (f) Remove screws (14) and balance weights (15). NOTE Balance weights are tach welded in position. Use a chisel to break them loose. (g) Place rotor assembly in an oven and bake at 356°F (180°C) for 3.0 to 3.5 hours. WARNING Wear heat resistant gloves when handling heated rotor assembly. Failure to observe this warning could result in servere personal injury or death. CAUTION Do not allow press to exert pressure on rotor core winding as damage may result. Failure to observe this caution could result in equipment damage. (h) Remove rotor assembly from oven and press shaft (16) and key (17) from rotor core (18). 3-288
