I recently acquired a T generator that appears to be in fairly good shape, but the brush plate insulator is missing a small piece where the 3rd brush rides. I see that Langs does carry complete assembles, and two different sets of insulators (one of which needs to be modified). The brush holders and insulators are riveted so they obviously need to be drilled out. So I'm looking for advice on how to drill them out and rerivet them, and any other advice. Gary
Gary ; When the insulator under the insulated brush looks good,I leave it!! And just change the insulator under the 3'brush.
While I don't advocate leaving the carbon/oil soaked insulator under the positive brush holder, Anthonie's method will save you from having to drill and tap the brush holders.
I mostly replace the insulator plates the way Anthonie does but sometimes you need to replace it all.
Here is the way I change the + coil brush holder.
I recommend using the FunProjects generator brushplate insulators and install them using the MTFCA "Brushplate Rebuilding" video.
The grey fiber insulators being sold require modification and the rivet holes are not correctly located making installation difficult.
The FP insulators are electrical grade fiberglass precision laser cut using original Ford specifications.
Lang's also sell a completely rebuilt generator brushplate.

I really appreciate all of the responses from you guys. It's a good feeling knowing that there is so much knowledge out there. I had an emergency plumbing job I had to do for my mother-in-law today, so now I will be able to order my insulators. Thanks again.
