Topic: Rear wheel sitting crooked after bearing replacement, not fitting right

As stated earlier, it might be straightened with some heat and patience .

For the swingarm to get bent like that, I suspect that something got caught between the sprocket and the swingarm.  Most other damaged swingarms were bent along the tube and more towards the front.  It also looks as tho the shock / axle bracket is bent outwards but it could just be the picture.

 if you want to change swingarm length, or axle ends, now is the time..

Looks like the PO got rear ended from the left to do that sort of damage to a swing arm.  Inside of the axle slot on the left  is pretty chewed up.

I would try and straighten it. Some heat will be needed to get that wrinkled bit straight. I have straightened a few that were cranked to one side or twisted so one leg is higher than the other, but not with a bend right by the web. The forks are not highly stressed, the web around the axle slot and shock mount carry the weight of the bike and the legs pretty much just hold the axle in position. Excepting sidecar use, side load is not huge. You have some moment from the tire contact patch in corners, and the chain force, but almost all load is perpendicular to the axle.

I've got a bench vise I can use to hold it down while I heat it up, so I'll try that and see how close I can get it to be straight again. Otherwise, off to the salvage yards!

Any recommendations on swapable swingarms?

Sounds like fun! I busted a couple spokes hurdling a RR grade on my CB, just once, long ago. Lucky for me the broken spokes were rear outside. My dirt bike was much more suited for jumps and went airborne as often as possible, but no bent swingarms on CB or SL. All landings square to ground as well.

Where are you Vesperia? Slicks in Mason used to have a pretty good salvage operation. I don't know if their new place in Dansville got the salvage yard.
Member Yamahawk in Toledo has salvage parts available and might steer you to Ohio MC salvage yards.
Its been a while but I have been to CycleReCycle in Indianapolis. They have lots of used parts.Call them with your needs.

I live in SouthWest Michigan, but I bet I can make a day trip to Ohio or Indiana to find a yard.

I am in Kalamazoo...unfortunately, I don't have the swingarm you need, mostly cb750 stuff.  There is a salvage yard near three rivers.  I have called them, but they claim they don't have stuff,then when I ride by, I can see plenty of 1970's Japanese iron sitting around...so I don't know.  Put a want ad up here and I bet someone is parting a bike with the swing arm you need.  Ebay works good too.  Should not be an unobtainium part.

Hold up...is your bike a K or an F model?  I just remembered having a K 550 swingarm leftover from a project a few years ago but I can't remember if I ever got rid of it or not.  I will have to dig around and see if I still have it.

It's a K Model actually. Let me know if you have it and I'll gladly pay for it!

[RAFster122s]

F swingarms are different on the 550...so you want a K swingarm.

I’ve seen one bent like that! “Someone” backed into the bike, in the garage..... SUV pinned the bike and twisted the back. Is the rim bent too??

[754]

 I bet the wheel , or rim has been changed..

I'll check out the rear wheel and see if it's bent out of shape. Is there honestly a good way to tell? Aside from spinning it and seeing if it wobbles?

[754]

just spin it.

I would try and straighten it.

I wouldn't even try to straighten an arm that bent; the damage is more than that bulge in the tube, it's also transferred to the tube on the other side. Whatever bent the arm is maybe what trashed the bearing?

It's possible, the bike only has around 9800 miles on it.

After getting a new swingarm the crooked wheel has been fixed! Huzzah!
