7.7.2. Repair and check of the generator


1. Remove the generator from the car.
2. For simplification of assembly of the generator apply a combination tag on a forward and back cover of the generator.
3. Unscrew the nut fixing a generator pulley to a rotor axis and remove a pulley.
4. Unscrew 4 coupling bolts (are specified by shooters) connecting a lobby and a back cover of the generator.
5. Remove a forward cover of the generator.
6. Remove a generator rotor.
7. Unscrew nuts (are specified by shooters) fastenings of a back casing of the generator.
8. Remove a back casing of the generator.
9. Unscrew screws (strelvam are specified) fastenings of plates with diodes.
10. Remove the brush holder from plates with diodes.
11. Remove tension regulator.
12. Remove a plate with diodes from the generator stator.


Check of serviceability of diodes

1. Using an ohmmeter, check resistance between contact rings of the generator. Resistance between contact rings of the generator has to make several Ohm.
2. Check resistance between contact rings of the generator and a rotor of the generator. At the same time resistance has to be equal to infinity.
3. Check resistance between the central contact and each winding of the stator. In case of break of a winding of the stator the stator needs to be replaced.
4. Check serviceability of diodes. At the same time change polarity of probes at connection to the diode. In one case the ohmmeter has to show small resistance, and in the second case very high resistance (see rice. Check of serviceability of diodes).


1. Assembly is made in the sequence, the return to removal.
2. Before installation of the brush holder move brushes into the brush holder and a wire record them in this situation. after installation of a forward and back cover on the generator and connections by their coupling bolts take the wire holding generator brushes.
