Generators & Regulators: Overhaul: Generator: Disassembly

Use generator Pulley Set Nut Wrench Set (SST 09820-63010) to remove generator pulley. To remove pulley, install SST "A" and "B" to rotor shaft and tighten SST "B" clockwise to 29 ft. lbs. (39 N.m). See Figure. Place SST "C" securely into a vise. Verify that SST "A" is secured to rotor shaft and install SST "A" and "B" and generator into SST "C". Turn SST "A" in correct direction to loosen pulley nut. See Figure. To prevent damage to rotor shaft, DO NOT loosen pulley nut more than 1/2 turn. Remove generator from SST "C". Turn SST "A" and "B", remove pulley nut and pulley.
Remove rear end cover. See Fig 1. Remove terminal insulator. On 100-amp generator, remove brush holder. On 130-amp generator, remove seal plate with whole in it. Remove brush holder. Remove inner seal plate. On all generators, remove rotor from generator coil using Puller (SST 09286-46011). Remove generator washer from rotor.
