Topic: Rear wheel out of whack

[JBMorse]

After shelving my CB500 for years due to time and space restraints, I am slowly piecing it back together in my own shop. One of my tasks was to change the rear tire, and after doing so I cannot seem to get it lined up correctly on the bike.
The problem is that the hub seems to be too far to one side, the sprocket side. There isn't enough clearance between the chain and center stand. I don't think there's anything wrong with the swing arm of frame and I triple checked the manual and diagrams to get the axle spacers right.
It's hard to get the angles in a photo, but looking at the rear of the bike, the wheel is too far to the left.

My guess is there is a sprocket side collar/spacer, on the axle,  missing. Check a microfish?

It buries into a seal on the sprocket side of the hub, leaving about 1/4 to 1/2 showing.

Thanks for the suggestion. I studied the parts fiche carefully and found that the "rear brake panel" page shows a spacer by the brake hub and the "rear wheel" page shows the spacer you mention. I took the wheel off earlier today to ensure that it was in there and it was.
I looked at my second CB500 roller to compare the widths of the swing arm at the axle and it was the same as the one I'm having trouble with.
I guess I might take the time tomorrow to take off the rear wheel of my other bike and compare the assembly.

There are 3 spacers in toto. The rt side brake side. The one that is "in there" on the sprocket side. And one thatis partially in there and hangs out enough to space the wheel to the right away from the centerstand. Were you able to tighten down the rear axle or was it misbehaving as well?

On the fish the spacer  am speaking of is #6 and is virtually lost in the shadowing f the tire, but its there.

[JBMorse]

Yes I did find spacer #6 in place. The other spacer on the sprocket side, #12? I don't know if that's present or not. Is it between the bearing and hub? I'm not sure how I would see it without taking the bearing retainer and bearing out.

Maybe this picture will help a bit.




As for the center stand hitting the chain...mine does that too, when the exhaust is removed.

Thanks for the help folks. I studied my other CB500 and measured the distance from the hub to the chain adjuster on each side, and the measurements were the same as the bike I'm having the problem with. I think it was a matter of routing the chain correctly by the swingarm and then tightening it up. The center stand is bumping up against the chain but you may be right that the exhaust will prevent it from coming up that high.
Sorry I still can't get my flickr pictures to embed here, but here they are:

If I remember right the center stand "lever" bumps the exhaust, keeping it out of the way of the chain. I think the lesson here is that I am simply out of practice working on the SOHC4!
By the way, the rear wheel still looks a little off center but it might be the result of having a bent rear fender. I haven't gone to the trouble of removing the fender to have a look, but I remember it looked a little off center upon returning from my round country trip, on which the luggage rack was overloaded causing the bend.
