Generator Exploded View (Sheet 2 of 2)c. Disassembly (see figure 8-1).(1) Remove screws (l), nut (2), lockwasher (3),attaching screen (4) to generator and remove screen.(2) Remove screws (5), lockwashers (6), attachingend bell cover (7) to end bell and remove cover.(3) Remove screws (8) and lockwasher (9), andremove end bell assembly.(4) Remove “O” ring (12) from bearing housing.Remove and tag wiring harness from terminal board(20). Remove screws (19) and nuts (18) attaching ter-minal board to exciter stator and remove terminalboard.(5) Remove four screws (14) and lockwasher (15)attaching exciter stator (17) to end bell (16) and re-move exciter stator.(6) Remove eight screws (24) attaching couplingdisk (27) to rotor shaft and remove coupling, lockplate (25) and retaining ring (26).(7) Remove generator fan (28) which is now free.Do not remove balance screw from fan (28).(8) Remove rotor assembly from stator assembly(53).(9) For MEP-003A, remove screw (29), lock-washer (30) and flatwasher (31) attaching bearing (32)to rotor shaft and remove bearing, bearing retainer(33) and shaft collar (34). For MEP-112A, removescrew (29), lockwasher (30), retainer washer (31A)and Belleville washer (32A), attaching bearing (32)to rotor shaft and remove bearing retainer (33) andshaft collar (34).(10) If necessary, remove diodes from rotor asgiven in paragraph 8-2a above.Do not remove exciter rotor from rotor shaft.Do not remove balance weight (52E) fromrotor.d. Inspect. Visually inspect windings and lead con-nections. Check that diodes are securely mounted onheat sinks. Clean dust, dirt, and grease from diodes.Clean windings and drain holes. Check that end bear-ing is not damaged or worn. Inspect cooling fan andcoupling for damage.e. Testing Exciter Stator (Field) (High PotentialTest).Observe safety regulations. The voltages usedin this test are dangerous to human life. Con-tact with the leads or the windings under testmay cause severe, and possibly fatal, shock.Arrange the high voltage leads so that they arenot in a position to be accidentally touched.Keep clear of all energized parts. Always re-duce the test voltage to zero and ground thewinding under test before making any mechan-ical or electrical adjustments on the equip-ment. When grounding out windings which havebeen tested, always connect the connectionwire to ground first, and then to the winding.Never perform this test without at least oneother person assisting. Generator frame shallbe securely grounded.(1) General. The high potential test is performedto determine whether or not the insulation of theequipment under test is defective. It is customary todetermine whether electrical equipment will withstandnormal voltage stresses by means of a test in whichhigher voltages than normal are applied -for a definiteChange 2 8-3
