I replaced the bushing in my three brush generator a couple of months ago. I bought the bushing from Vanpelt and used a internal bearing puller to get the old one out. I supported the end plate on the top on my vise and used the slide hammer to pull the bushing out from below. It was stubborn at first, but then once moving came out easily.
