Tried that. Not enough of a lip to grab on to on the race and nothing for the center screw to push against.

Ed,
Huh,
in that case a long bar and tap it out from the other end.

Dave,
There is nothing for the bar to catch on. There are no exposed edges on the race for anything to catch on to. It appears to be designed for insertion only. No replacements allowed.

Ed,
If there is no place to push or pull on the top of that race, then I would suggest using a dremel tool with a cut off disk. Score it in two or three places about 2/3 through then give it a rap on the edge of the race at the score with a small chisel. It will split at the score.
I have removed many a froze up wheel bearing that way.
Jerry.

Ed,
Well in that case you are on your own mate
Just kidding Ed. There must be some way to get it out, the Chinese just make them, they didn't design it.

That's one of the very few places where I'd use a Dremel and a cutoff saw. Start grinding in your own slots for tapping it out, and if that fails, cut them out.

That's my back up plan, use a Dremel with a cut-off disk.
I finally got that snap ring out, what a difference a quality tool makes.
So I was able to knock out the last shaft that was still in the head. To my surprise there was a bearing attached to it that I couldn't see because the large gear was blocking it. So now I'll be short one of the 6007 bearings. Oh well, I still have to order the tapered roller bearings yet anyway.
Anybody know a good place to get P/6 tapered roller bearings? I've been searching most of the afternoon with no luck. I found some P/5s but don't want to spend that kind of money since it's overkill for this mill.

Ed,
I changed the bearing on my RF 31, the spindles are probably the same, I don't remember having a problem getting the outer race out.
If there had been a problem I would remember something, problems tend to be remembered.
I'm sure there were a couple of groves to give me access to tap the outer race out.
Although that doesn't help you much

Actually Dave, it did help. It motivated me to go and see if there were any groves and there were not. But then I decided to look underneath the round rubber gasket the cushions the quill from the mill head and underneath the gasket I found three holes that appear to be for inserting a pin punch to tap out the race. I may be in luck after all.

Anybody know of an online bearing supplier that would have ABEC 3 or P6 or class 6, whatever you want to call it, tapered roller bearings? I've been looking for days with no results. Surely there has to be a bearing store that can source the size bearings I need for the mill.
