January 1, 200917 yr Hello I'm in the process of replacing the swingarm bearings on my '02 Beta Rev 3. I got the pivot pit out OK, but the old needle bearings are proving more difficult to remove! Is there a recognized method of shifting these that i should try before i resort to the big hammer/fail/ take to someone who know's what he's doing system that i so often seem to use!! Also (whilst it's apart) whats the best method of lubricating the spherical shock bearings. I can't feel and up and down play so am assuming they are OK. Cheers
January 1, 200917 yr hi, the best way to remove the swingarm bearings is to use a socket thats the same diameter as the bearing to push it out. Have a big socket on one side that will not obstruct the bearing, and a smaler socket the same size as the bearing, on the other side. Then use a vice to push them out. If you can make any sense of that then it will take a maximum of one minute to pop them out. Putting them in is exactly the same, just in reverse. Im affraid i cannot help you with the shock bearing as im in the same boat as you (cant get it out!). Anyway hope this helps max

If you can make any sense of that then it will take a maximum of one minute to pop them out. Putting them in is exactly the same, just in reverse. max Just to add to Max's idea, you can also use a short piece of threaded rod through the sockets with nuts on either end and tightening the nuts will slowly push the bearings in and out (it's a little less cumbersome than trying to coordinate the swingarm position and keep track of both sockets in a vice). It's a lot less damaging on the bearings (if you don't have a press and must use a hammer) and as it is slow and controlled, it's easy to seat bearings to just the right depth if theres not a shoulder for the bearing to seat against. Jon Forgot to add: Usually the Heim Joints (the self-aligning bearings in the shock) are a press fit, but sometimes theres a very thin wire circlip on either side to hold them, so you might want to look for that.

January 1, 200917 yr A trick you can use,is pour boiling water on the ali,helps break to bond between the bearing shell and the swing arm
January 2, 200917 yr Shoving the new ones in sounds easy, it is... just shove the bearings in a bag in the freezer, heat the swingarm and then last second pop them out the freezer and in, should slot in easy, once in leave for about 10 mins then heat the swingarm and bearing up very slowly... should make them stay in
