Disassembly (100-Amp)

Use generator Pulley Set Nut Wrench Set (SST 09820-63011) to remove generator 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. 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 3 nuts and rear end cover. See Fig 1. Remove nut and terminal insulator. Remove 2 screws and brush holder.
