Changing swinger bearings to bushings, got a question...

[Qdude79]

Does this collar come out/off? It looked like a piece of the swinger when I banged out the bearings...

[tri again]

What year / machine?
I've done a 250r and 250sx swing arm bearings / bushings.

Do you have a
service manual?

A parts diagram may also go a long way until you get some better advice.

At least it doesn't look rusty like all of mine.

Hello


That is a removable collar, see page in link below. It looks like your arm has been very HEAVILY coated powder coating or something thick. There is a clearly defined machined area on each end of the swing arm. You will see that machined area in the manual and on your swing arm if you look closely. I can clearly make them out in the photo. This area as well as the collar shown in your photo is covered by the metal dust seal which has a rubber inner to seal out dust and water etc.

What year and model is it exactly?

Hope this info helps.

Yes both collars have to come out. I have a set in my 83 250r swingarm.Top swingarm.

My apologies, fellas, it was late and I forgot to mention that it's an '85 250R. Just got it back from powder coat.

Hello


That's what I figured so here's your potential problem. The end cap seals act like a spacer without them your swing arm will have a little play and you will have to take up extra clearance by tightenung bolt causing slight stress in frame. Not the best thing, not the worst. Your end caps may not go over swing arm paint enough to properly seat. This means once installed your swing arm will be too wide to fit. If they do not go down all the way, either remove the rubber seal on the sides or get a file and file away that nice new powder coating on the machined lips I spoke of. You can also grind the end seals so they are a bit more shallow.


Hope this info helps.

Ok Barnett, so if I'm reading you correctly, it may be a bit loose without the end caps, may be too tight with 'em. Correct?

[Qdude79]

Also, the service manual says to knock these things out with a drift. With them being in there so tight after 27+ years (presumably), is there another method that might be better? I picture myself with a bfh, and I don't like that.

[Dave8338]

They are a press fit and not all that tight. Looking at how clean yours are, a couple smacks with a drift and a and they'll likely fall out and hit the floor. They go back in with a few taps of a small dead blow or can be pressed in if you have access to a press (though NOT needed).

[Qdude79]

I'll give it a few good pops and see what happens. I just know how things can get with "the hamma."

You can also try lining up the bushing with a slightly undersized socket on one side and an oversized socket on the other and then put it all in a bench vise and push them out. Get an extra pair of hands to help you so you don’t wreck that powder-coating. The sockets might not be long enough to get them all the way out, but at least they will be freed up. You can put the new ones in the same way or build a tool with threaded rod and some washers to pull them into the swing-arm.

PS. Do whatever you have to in order run the sealing end caps, you’ll be glad you did in the long run.

According to Qdude79's thread title he is changing his swinger "bearings" to "bushings".

If this is in fact accurate then that collar is no longer required and should be just coaxed out of the swinger. It should not be that big of a deal to put a socket with extension or drift or equivalent and drive it out.

Here is a 250r swinger with the bushings installed, no collars or sleeves required.

[Qdude79]

All good advice, fellas, thank you. Gonna try the for a bit, sockets if that doesn't work. With any luck, they'll pop right out and I'll have to find other ways to screw up my new powder!

PS- Mr. Clean, how did you get a swinger on to a granite counter top and live to tell about it????

[Mr. Clean]

Part of your problem may be having that swinger powder coated with that collar installed. Is there any powder overlapped onto the collar?

Mrs. Clean is the BEST and the swinger and parts are perfectly CLEAN!!

[Qdude79]

There may be just a touch overlapped, as I recall.

Mrs. Qdude would have shot first, asked questions later!
