Fred, Greg
Thanks for the advice, my local auto parts store loaned me a blind
bearing puller kit and the bearing came right out. Well, actually the
sleeve that holds the bearing came right out. The bearing race came out
of the sleeve using an appropriatly sized socket and a hammer.

From the looks of both the races and the rollers, the race was
originally driven into the swingarm sleeve using the rest of the bearing
as a driver. Ouch. Nice roller sized depressions in both races and a
dent in the top of the rollers where they were pushed on by the inner
race.

Since the swingarm isn't exactly a high speed bearing application it
probably isn't critical that this bearing is pristine, but I figured as
long as I can see it I may as well service it.

The tips are split into four sections. There's a lip on the end that
fits behind the bearing race, and a threaded spreader that you tighten
up, locking the tip behind the race. Once it's tight, the slide hammer
whacks the sucker out in about 5 whacks. I don't think there's enough
room back there to use a normal 3 or 4-jaw puller.

Interesting...I'm always looking for better/different tools to help pull


bearings, etc.

Could you explain how the tips work? The pictures online aren't very
clear (neither is Harbor Freight's description). And, since this is a
special order item (at least for my local store), I can't go look at it
in person, either.

Actually, the one I bought is more specialized:

I used the same tool, Fred...and found it useful for other tasks, too.

What you need is a blind bearing puller. I got one from Harbor Freight.

Hey all,
I have a swingarm pivot bearing that feels rough enough that I plan to
change it. Looking at it I'm hoping to be able to pull the race with a
slide hammer provided I can get something behind the race to attach the
slide hammer to. Anyone out there been down this road? If there is a
"right" way to do this I'd like to figure out what it is.
Thanks,
Rob
