ARMYTM 9-6115-464-34 AIR FORCE TO 35C2-3-445-2 NAVY NAVFAC P-8-624-34 Section XIII. MAINTENANCE OF GENERATOR ASSEMBLIES 3-94. GENERAL. This section contains maintenance procedures for the generator assemblies. There are two types of generators used in the generator set. The 50/60 Hz generator is used in both the 50/60 Hz utility, and 50/60 Hz precise generator sets. The 400 Hz generator is used only in the 400 Hz precise generator set. Both generators are drip-proof, rotating-field, synchronous, brushless, fan cooled units. Mounting for the generator is provided by the generator feet bolted to the skid base and the housing bolted to the engine flywheel housing. Rotational power is provided by the blower and coupling assembly which is bolted to the generator rotor shaft and the engine flywheel. 3-95. GENERATOR MAINTENANCE INSTRUCTIONS. a. Removal. Refer to paragraph 2–7a. for generator removal procedure. b. Disassembly (1) Disassemble generator by following the ascending sequence of index numbers assigned to figure 3-136 only as required to replace damaged or defective components. (2) Remove screw (1, figure 3-136) and Iockwashers (2) to remove drip cover (3). (3) Remove screws (4) and Iockwashers (5) to remove screen guard (6). (4) Remove screws (7) and Iockwashers (8) to remove lead block assembly (9) and gasket (10). NOTE Tag electrical leads to insure proper positioning at installation. loosen clamping screws to relieve tension on the leads. (5) Remove screws (11) and Iockwashers (12) to remove screen guard (13). (6) Remove screws (14) and Iockwashers (15) to remove cover plate (16). (7) Remove plug (17), screw (18) and Iockwasher (19). (8) Remove screws (18) and Iockwashers (21). Using a suitable puller, remove bearing housing (22). (9) Thread five turns of screw (18) into rotor shaft and, using a suitable puller, remove bearing (23). (10) Support bearing on the head of a suitable press and press out adapter (24). (11) Remove the lifting eye bolt from the generator stator. (12) Cut a sufficient length of 1/2 inch bar stock steel to fit across the diameter of the coupling disc end of the generator assembly. Drilling operations create metal chips which may enter the eye. Wearing of goggles is required. Failure to observe this warning could result in servere personal injury or death. (13) Center punch and drill a 1-inch hole through the center of the bar stock. 3-285 WARNING
