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). (Scheme 4) 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. (Scheme 4) 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. (Scheme 2) 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.

Assembly
To assemble, reverse disassembly procedure. Use generator Pulley Set Nut Wrench Set (SST 09820-63010) to install generator pulley. Place SST "C" securely into a vise. Install SST "A" and "B" and generator into SST "C". (Scheme 4) On 100-amp generator only, before installing brush holder, push brushes back into holder and install.039" (1 mm) pin into brush holder hole. (Scheme 5) Tighten pulley nut in the opposite direction of disassembly. See TORQUE SPECIFICATIONS. Using 21 mm socket (100-amp generator) or 27 mm socket (130-amp generator), carefully press in generator coil. To complete assembly, reverse disassembly procedure. After completing assembly, verify rotor turns smoothly. After completing assembly, verify rotor turns smoothly.
