Replacing the generator brushes on the Prior

There are frequent cases when, due to sufficiently strong wear of the generator brushes, the battery charge disappears. At first, it may be slightly lower, and over time it will become weaker and weaker. If you notice similar symptoms on your Prior, then it is possible that the reason is precisely the wear of the generator brushes. In order to replace them, it is best to remove the alternator from the vehicle. If you understand that you yourself cannot cope, then it is better to send the generator for repair. https://generatorservis.by/... And after that, you will need the following list of tools:

  1. Open-end wrench 13
  2. Flat screwdriver
  3. 10 head with a knob or ratchet handle

So, when the generator was removed from the car, the first step is to remove the plastic cover by prying it with a screwdriver:

After that, we get access to the brushes themselves. Now you need to disconnect the plug with the wiring that is connected to them:

And then unscrew the two bolts that secure the brushes along the edges. Everything is clearly shown in the photo below:

But that's not all, since there is one more mount, and in order to get rid of it, you will need to unscrew the nut with a 13 key, as you can see in the picture below:

But now the procedure for replacing brushes on the Lada Priora generator is practically considered complete. The brushes are free and can be easily removed:

If you are not sure that the reason for the loss of battery charging is in the brushes, it is enough to measure their residual length, which should not be less than 5 mm. If you find that the length is less than acceptable, then there is no doubt that they need to be changed. Also, see how evenly worn both brushes are. It happens that one is practically erased, and the second is still quite suitable - which can also affect the performance of the entire generator.

The price of new brushes for Priora is about 150 rubles for a more or less high-quality part. Of course, you can find it cheaper, but you should not save on the “health” of your car, since then you can spend even more money on extraordinary repairs. Installation is carried out in the reverse order and after that the efficiency of the generator as a whole is checked. If the problem with charging is solved, then it was the voltage regulator that was the problem, if not, look for another reason!
