It was forged in the fires of mount Kawasaki, only there can it be undone..

Omfg, I have been trying to remove two swingarm needle bearings from my GPZ750 for TWO WEEKS! I am using a bearing puller I got from autozone, it has the slide hammer and everything. I have soaked them in penetrating oil, heated the outside, froze it overnight and then heated the outside hammered the ever loving piss out of it and nothing. Doesn't seem to budge at all. It seems to be rusted in there or something. Bike has been sitting for a decade. Is there anything else I can do? I really want to embed this swingarm into the drywall. I took it to the shop yesterday but he just told me to freeze it. Any other tricks? Thanks

I have had pilot bearings seize like that, and its a serious PITA to get them out. What I have done, and- I _AM NOT_ TELLING YOU TO DO THIS- is to use a die grinder and carbide burr and very carefully grind a notch into the bearing race, then using a chisel split it and work it out from there. But the above is only what I have done and probably should not be attempted. Although it has worked several times. I have also used an end mill to very carfull mill the bearing race out, but that takes a very, very long time to set up properly. Oh, and you need a mill.

Thanks, I am trying to not use power tools until I have exhausted every other non destructive resource, and unfortunately no mill.

you could always try a knife file or a small hack saw blade, I've had to do that multiple times. You could also try heating it up and as it cools spray it with some penetrating oil. This will cause a sort of capillary action and pull the penetrating oil into the joint.

I did something similar to what Firestarter did, but just used a dremel and a hacksaw blade to cut a slice into the race. Used the dremel to do the majority of the work, then the hacksaw and chisel to do the rest.

Best of luck with it.

As above. You're not going to be able to get them out intact or re-use them, so brute force and cold chisels is in order.

It should be way too hard for a hacksaw blade.
If you've been beating on it, the needles should already be gone so it's only the outer shell?
Use Dremel with grinding stone or carbide burr at 11:00 o'clock position (viewed from 'left' if swing arm was still in bike)

you could try using sockets and threaded rod to make a puller. find a socket the same od that will just slip in the swing arm bore then find another socket big enough to pull the race into. threaded rod down the centers, tighten and it should pull it out

Dremel and chisel. But the outer race is hardened, and is prone to shatter. Wear eye protection.

Finally!! I used a dremel and a carbide burr, and cut the suckers in half!!! Thanks for the help.

There is no problem that can't be solved by violence. It works (?) for the world's leaders so it should work for us!
