What diameter would you guess the posts might be?

Yes they are bent tabs. I would probably guess your tab was broken like mine was. Here is a picture of the back of the plate.

If you zoom in you can see one side with the originals and the other side with the rivets I made.

If you’re talking about the posts that hold the plate down I’m guessing 3/16”-1/4” maybe.

You can see them in one of the earlier pictures.

Hi Kevin - Got the brush plate off by cutting into the washers on the posts with a cutting disk and Dremel tool. Once the plate was off, drilled a hole in the center of the posts and threaded with 3.05 tap. The photos tell the story. Will put some Loctite on the threads when I reassemble. Oh yes, bent the brush holder tabs so they are tight again. Success!

Nicely done. Saved another pump and $1000++.

Just looking at the picture with the screws in it. You might want to try to get different head screws so the brush coil wire doesn’t touch them.
