Generator brushes are replaced as an assembly with a brush holder.
For clarity, we show the operation of replacing the brushes on the removed generator, but they can also be changed on the car.
Remove the wire plug from the output «67» generator (brush holder outlet).
Using a Phillips screwdriver, unscrew the screw securing the brush holder...
...and take it out.
The brushes must protrude from the brush holder by at least 5 mm. Otherwise, replace the brush holder.
We blow the rotor with compressed air through the hole in the generator cover to remove coal dust. Install the brush holder in reverse order.
