1. Clean and blow out the generator with compressed air. Loosen the screw and remove the brush holder 2 with brushes.
2. Remove the alternator pulley using tool 67.7823.9504. To do this, lock the pulley with the grip included in the tool kit, unscrew the pulley fastening nut and compress the pulley with a puller. Remove the pulley key and taper washer. Tool 67.7823.9504 includes a conventional puller and gripper. The latter consists of two steel half rings, which are inserted into the pulley stream. The half rings have the same section as the alternator drive belt. On the one hand, they are hinged, and on the other hand, they are equipped with levers that are compressed by hand when the nut is unscrewed and the pulley is removed.
3. Unscrew the nuts of the four tie bolts 16 and disconnect the rear cover 18 with the stator 8 and the rectifier unit 6 from the front cover 11 with the rotor 9.
4. Remove the rotor with spacer from the front cover bearing.
5. Unscrew the nuts of the screws connecting the tips of the valves to the stator winding terminals, remove the plug of the central terminal of the stator winding from block 4 and disconnect the stator from the rear cover.
