- Remove rear end cover. Remove nut and terminal insulator. Remove generator brush holder. See Fig 1. Remove regulator assembly. Remove generator holder with rectifier. 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 generator rectifier end frame using Puller (SST 09286-46011). Remove generator washer from rotor. Remove rotor from generator rectifier end frame.
