Generator parts 37.3701
1 – voltage regulator assembly with brush holder for generators produced since 1996.; 2 – voltage regulator and brush holder for generators produced before 1996.; 3 – additional diode output block; 4 – insulating bushings; 5 – rectifier block; 6 – contact bolt; 7 — stator; 8 — rotor; 9 – spacer sleeve; 10 – inner bearing mounting washer; 11 – drive side cover; 12 – pulley; 13 – outer bearing mounting washer; 14 – tension bolt; 15 – Front rotor ball bearing; 16 – bushing; 17 – cover from the contact ring side; 18 – buffer bushing; 19 – pressure sleeve; 20 – capacitor

1 – casing; 2 – voltage regulator; 3 – base; 4 – brush holder with brushes; 5 – generator cover from the contact ring side; 6 – block of the plug of the central terminal of the stator winding; 7 – terminal "15" of the generator (terminal "B" of the voltage regulator)
The 67.7823.9504 tool kit includes a standard puller and a grip. The latter consists of two steel half rings that are inserted into the pulley groove. The half rings have the same cross-section as the generator drive belt. On one side, they are connected by a hinge, and on the other, they are equipped with levers that are squeezed with one hand when removing the pulley.
Generator 37.3701
1. Clean and blow out the generator with compressed air.
2. Lock the alternator pulley with the grip included in the 67.7823.9504 tool kit, unscrew the pulley mounting nut and press the pulley with a puller. Remove the pulley key and conical washer.
3. Disconnect the wire from the "B" plug of the voltage regulator.
4. Disconnect the regulator and capacitor wires from the generator terminal "30" and unscrew the voltage regulator mounting screws.
5. For generators manufactured before 1996, to avoid breaking the brushes when removing the brush holder, insert a screwdriver blade between the regulator housing 2 (see fig. Generator parts 37.3701) and the brush holder and partially pull the regulator out of the generator, leaving the brush holder in place.

6. After this, tilt and remove the regulator together with the brush holder from the generator. Remove the capacitor 20 by unscrewing the fastening screw.
7. Loosen the nuts of the tie bolts 14 and remove the generator cover 11 and rotor 8. Loosen the nuts of the screws connecting the diode tips to the stator winding terminals and remove the stator 7 from the generator cover 17.
8. Unscrew the nut of the contact bolt 6, disconnect the plug of the additional diode wire from the block 3 and remove the rectifier block 5.
Generator G-222
1. The G-222 generator is disassembled in the same order. To remove the voltage regulator, unscrew the mounting screws and remove the casing 1 (see fig. Details of the front part of the G-222 generator) complete with regulator 2, base 3 and brush holder 4.
2. Then, by unscrewing the screws, separate the regulator, the base and the brush holder with the brushes.
3. Further disassembly of the G-222 generator is similar to disassembly of the 37.3701 generator.
