Generators & Regulators: Overhaul: Generator: Disassembly

Remove nut and terminal insulator. Remove plate terminal, rear end cover and brush holder cover. See Fig 1. Remove brush holder and voltage regulator. Remove seal plate from rectifier end frame. Remove diode (rectifier) holder. Remove rubber insulators. 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 Fig 2. 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 Fig 2. 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 rectifier end frame using Puller (SST 09286-46011). Remove generator washer. Remove rotor from drive end frame (stator).
