swingarm bearings

[jsandidge]

Anyone know where to get aftermarket swingarm bearings? OEM looks pretty pricey. I think I need 17mm x 40mm x 15.25mm.

Thanks

Pull one of the bearings, read the numbers/letters on it and call Motion Industries, KAMAN Industries, NAPA, O'Reilly's, Amazon.Com, etc. and get a pair of replacements for MUCH less.

Looks like a 09265-17012. Probably a KOYO 30203JR. Should be able to find that at a auto parts or bearing shop.

That's the one. I'm going to check O'Reilley's and see if they have a slide hammer that will work to pull the outer race. I think the one they loaned me to pull my fork seals will work.

O'Reilly's can only get the ones without the rubber seal, but I did find the ones with th seal on Amazon. 15.50 each plus 9.95 shipping. For 41.00 shipped I get the pair. Not too bad. The O'Reilley's slide hammer did the trick on getting the races out. A little finicky, but they're out.

Just curious -- why are you replacing them?

These tapered bearings are mega-overkill in this application (shaftie swingarms), and will pretty much last forever.

The exception, of course, would be if the bike was stored in a swamp or something and they got corroded.

I've never had to replace a set of them yet and both of them are OEM. I've rarely had to adjust them, even.
Having said that, next time I check them I might find the oldest ones are worn past adjustment, but they've have 250K to get there, and I might get the chance to fit the spare set I bought 20 years ago in the expectation that I'd need them at some point.

I've never owned a G, but I've owned a few Yamaha XJ shafties over the years and the swingarm bearings wear out quite readily over time. The bearings are quite small compared to the roller bearings of a chain drive swingarm.

I pulled everything apart to get the frame and swingarm powdercoated. The bike sat for about 14 years. Upon inspection, I found the races were a little notched. Had the same issue with the steering stem races, which I've already sorted.
