Charging System - Generators & Regulators: Overhaul Lexus LX J100

Disassembly

1. Remove rear end cover (if equipped). (Scheme 18) Remove brush holder and IC regulator. Remove diode assembly. Remove rubber insulators or seal plate (if equipped). Use generator Pulley Set Nut Wrench Set (SST 09820-63010) to remove generator pulley.
2. To remove pulley, install SST "A" and "B" to rotor shaft and tighten SST "B" clockwise to 29 ft. lbs. (39 N.m). (Scheme 19) 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 19) To prevent damage to rotor shaft, DO NOT loosen pulley nut more than 1/2 turn. Remove SST "A" and "B" and generator from SST "C". Remove SST "A" and "B" from rotor shaft, and remove pulley nut and pulley.
3. Remove rectifier and frame using appropriate puller. Remove generator washer (if equipped). Remove rotor from drive end frame (stator).

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 19) Tighten pulley nut to 81 ft. lbs. (110 N.m) in the opposite direction of disassembly. After completing assembly, verify rotor turns smoothly.
