Hello all,

I have a 1976 CB550 that I had a local motorcycle shop replace the rear bearing in the hub assembly. I noticed that after the bearing were replaced I am struggling to get the wheel and spacer on. I have to put the rear spacer on at an angle and force it into place, however the rear wheel sits crooked.

Has anyone encountered this issue or is it possible the bearing's are not sitting right int he hub?

Thanks for any help!

 It looks to me like the wheel is bent, more than it's crooked. If you put the bike on the center stand and spin it, does it spin true or does it wobble?

 The only other thing I can think of is that it's surprisingly common for part #14 to come out stuck to the old bearing and it gets left out. This will cause issues as well.

If the spacers are tight the bearings and or internal spacers are not assembled correctly and the bearings will be overloaded and fail prematurely

Looks like the swingarm itself is shifted to the right; the shocks look to be at an angle. The right side axle spacer is in place, and the brake backing plate seems to be sitting at the proper depth in the hub, so the bearings and or spacers are not the reason the center of the tire is so far to the right. Bent swingarm?

The swing arm looks bent to me.. Not sure how the wheel bearing change bent the swingarm.  Maybe it was bent before and you didn't notice?

Could the spacers be reversed? Or on wrong side?

The wheel does wobble a bit, so it's very possible it's bent out of place. I would have thought the dealership would have told me when they put on the new tire and balanced it.

I'll remove the swing arm and see if it's bent out of shape.

I've actually never had this bike in running condition yet (bought 2 years ago as a project that didn't run) so I may have never noticed it as I was working on different items.

 loosen axle nut, see if  a gap appears., if the #14 spacer is out the sprocket carrier may sit in further and it looks like that.
then the swingarm may pull in tighter, bending one side or the  other.

if you brought that to some kind of a shop, motorcycle, go kart or scooter shop and they did any work on it, and gave it back to you like it is now, i'd mark that on my list of not to take my bike to that shop again, or at least any shop. if there was something wrong or bent when you dropped it off, they should've said something then, but if they said ok pick it up, that explains why didn't say anything to begin with, and honestly, i'd ask em about returning you payment that went for service work. if they say no, bring your bike back and set up an umbrella outside of their store with a picket sign, they'll negotiate something. looks like they backed over it with a car. unless it was like that when you dropped it off.

it's difficult to find any shop that knows what's going on, or a mechanic that'll try to do it right. i got a friend that rode bikes when he was young. now he's past 60 and the first mc shop he applied to work for as mechanic hired him. his first project was a ktm open class or big bike motor size, for some trivial adjustment. my friend fixed it and decided he'd try it out in the parking lot. (he used to be able wheelie long distances any bike he'd get on including a 750 4, believe it or not standing on seat doing it.) so he gets on this newer ktm and looped it, (going over backwards,) on the asphalt. he got fired, right then, but the owner of ktm had to been kind of mad about that.

 I've seen 14 and 7 swapped too but that shouldn't cause a tilt, only off sides.

I actually think I found the issue, the left side of the swing arm is bent slightly upwards. You can see the slight bump where it is bent.

I only brought the rear wheel to the motorcycle shop, not the entire motorcycle.

I'll have to get another swing arm, hopefully I can find a good one locally or on eBay.

Thanks for the help everyone!

Frank, look at the tube just to the right of the chain guard mount. ;)

 I see it now. check the side of the axle plates there is paint missing. Put something flat against it, see if it's twisted.

How in the heck would a swing arm get bent like that??? Ves, you need to take a closer look at the rear wheel. Why did you have the bearing replaced? Was it totally fubar???

The bearing on the bad arm side was shot, I'm going to guess during some point in moving or transport it got bent but it could have been like that when I bought it and I never noticed.

 It would take a helluva whack to bend that arm like that. Is there any evidence of other damage on the bike? On that same side?

I'll give it a more thorough once over after I get back from work, as far as I could tell no.

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.
