How to replace generator rotor slip rings

One of the reasons for generator failure is wear of the rotor slip rings. Replacing them is more complicated than installing new brushes, but is quite within the power of a car enthusiast.

Tools:

• bearing puller;
  
• a pair of locksmith screwdrivers;
  
• hammer;
  
• a pair of socket heads;
  
• soldering iron

Generator manifold replacement process

It is necessary to disassemble the generator and remove the rotor. He is clamped in a vice. Using a puller, the bearing is removed.

Behind it is a cross-shaped contact protection. It is pryed off with a screwdriver and is also removed.

Next you need to cut the contacts from the windings. To do this, a screwdriver is attached to them one by one from the side of the rings, and they are interrupted with a hammer blow.

2 socket heads are placed on the anchor. They are used as a stop for screwdrivers, which need to be used to hook the rings into the slot.

The collector is removed, the dry glue on the shaft is cleaned off. The winding contacts are also protected from varnish.
New rings are pressed onto the shaft through a wooden or plastic lining.

Then the contacts on the collector and windings are soldered. If necessary, a jumper made of copper wire is laid between them.

Next, a cross-shaped protection is installed, the bearing is pressed in, and the generator is put back together. Everything is done with a minimum of tools, so replacing slip rings can be done without going to a car service center.
