Cleaning lnspection. and Repair

ARMY TM 9-6115-464-34 AIR FORCE TO 35C2-3-445-2 NAVY NAVFAC P-8-624-34 (14) Pry woodruff key (47) from keyway in rotor shaft and remove spacer (48). (15) Support head assembly (49) and using a center punch in the indentation in the end of the rotor shaft, drive the rotor assembly (50) out of the head assembly (49). (16) Remove snap ring (51) and bearing (52) and o-ring (55). NOTE It maybe necessary to press or drive the bearing (52) out of the head assembly (49). (17) Use a bearing puller to remove rear bearing (53) from rotor assembly (50). (18) Remove cover (54) and o-ring (55). c.Cleaning lnspection. and Repair WARNING Solvent, Dry Cleaning P-D-680, Type II is flammable and moderately toxic to skin, eyes and respiratory tract. Eye and skin protection required. Good general ventilation is normally adequate. Failure to observe this warning could result in servere personnel injury WARNING Compressed air used for cleaning and drying purposes can create airborne particles that may enter the eyes. Pressure shall not exceed 30 psig and use only with adequate chip guards and chipping goggles. Failure to observe this warning could result in servere personnel injury (1) Clean all non-electrical parts (housing fan, bearings, etc.) in solvent P-D-680 Type II and dry with filtered compressed air. (2) Clean all electrical parts with a soft bristled brush and filtered compressed air. (3) Inspect plate and rectifier assemblies for cracks, corrosion, and evidence of shorting or other damage. (4) Using an ohmmeter or similar testing device, test positive diode rectifier assembly as follows: (a) Connect positive lead of tester to heat sink and touch negative lead to lead of each diode. Tester should indicate open circuit at each diode. (b) Connect negative Iead to heat sink and touch positive lead to each diode lead. Tester should indicate continuity at each diode. (c) Replace positive diode rectifier assembly if any of the diodes fail to test correctly. (5) Test negative diode rectifier assembly as follows: (a) Connect negative lead of tester to heat sink and touch positive lead to lead of each diode. Tester should indicate open circuit at each diode. (b) Connect positive lead of tester to heat sink and touch negative lead to lead of each diode. Tester should indicate continuity at each diode. (c) Replace negative diode rectifier assembly if any diode fails to test correctly. (6) Visually inspect stator assembly for rub marks on the interior diameter, evidence of burned or shorted windings, and other damage. 3-16
