Hey guys I have removed the seals etc and have let the swingarm bearing soak in wd40 then tried to press it out with a socket and c- clamp with no success. I then tried to hammer it out with a long extension on the socket, and it still wont budge. Any other tips or ways to get the bearing out? I am pressing it from the inside of the swingarm out. I was thinking last resort have a machine shop press it out, but I'd hate to have to pay $70 labor or anything crazy.

i dont have experience with that particular model, but some models have a circlip that holds the bearing in place, like a piston circlip.

I looks like there might be a circlip on the inside, I cant seem to get it out though. This is all that's holding me back from installing my motor lol go figure.

Shouldn't be a circlip on that swingarm..

You'll need heat and the right setup of a press..

I actually use a length of threaded rod, a couple of sockets and nuts that are used to join the threaded rods.. All found at the local big box hardware store (orange signs).

Get the right amount of heat and penetrating oil in there and it will come out.

Coat the new ones with antiseize compound when you install and they'll be a damn sight easier to remove next time.

Thanks, will try again tomorrow! I doubt these have ever been greased or replaced.

the new ones should go in a lot easier than they old ones came out, provided you clean up the swingarm and lube everything well.

Good luck.

Sometimes, paying a shop to press them out is the best way to go.

Hey guys I had a shop press them in, and the problem is on the inside of the swingarm where the spacer and seal goes, the spacer seems bigger then where it is supposed to fit in. I don't understand since it came out of there, but I can't get it to go back in. Here's some pics of what I mean, the only thing i was thinking was maybe it had to be put in before the new bearing was pressed in?

The spacer should fit inside the seal..

Did you not get new ones with the bearing kit?

No I got a boss bearing kit for the swingarm and it didn't come with the inside spacers, I am waiting on my pivot works linkage kit as of now... I figured the spacer would go on the inside, then the seal on top but it just wont fit. Here are the spacers and seals that came for each end of the swingarm forks. I was thinking on the outside for it went Spacer > bearing spacer> spacer> then seal. For the inside they didn't give me a spacer except the one that came out and wont fit, and a seal. :think:

Must have gotten the wrong kit somehow. I've never had a problem with Pivot Works.. I'd contact Boss and see what they say.

Well the thing I don't get is the spacer came out, it must go in right? Im guessing without the spacer between the bearing and seal it would put more stress on the bearing itself? Thanks

The setups I have seen, you have a thrust washer, thrust bearing, thrust washer, then the seal with the spacer inside the seal.

I have no idea what your's looked like when it came apart, so I really don't understand why you have what you have now.

Looking at the pivot works kit for your bike, I'm guessing you got the wrong kit from boss..

They have this new invention called a service manual that has proven to be remarkably useful in situations like this.

lol I know how it came apart and it's the right kit from boss, everything fits that was included. Yeah it would be nice to have a clymers, but I like to figure things out myself in what should be a simple job.

*edit*

Okay you guys got me, I'm an idiot... The spacer doesn't go on the inside at all. :bang:

Well everythings back together, but I'm having one heck of a time getting the swingarm back into the frame with the collars staying in the seals. I have the shock and linkage out for more room right now, but my friend said to put the motor in first and it will help align the swingarm better? Seems like it won't fit with the collars installed in the seals, and it's weird one of the sleeves that fits inside the swingarm bearing is longer then the other, but the swing arm is the same width on each spar? Linkage and bearings suck!
