KLR rear sprocket bolts contacting swingarm





Kind of interesting to me. If I were to spin the wheel right now with a brand new swingarm the bolts would not contact it. I just bought the bike for cheap from a friend and he truthfully may not have known. He has owned this bike for the last 10 years maybe. But it has only moved 150mi... maybe. It's a 1990 with 7150mi on it.
What is the problem here? The bolt picture is not as shiney for the flash lit it up.

The bolts are inside out.

Would you say that about the 2001 KLR 2 ft from it?


Looks like the main axle is not oriented in the same fashion.
The Clymer shows the KLR on the cover with castle nut on caliper side whereas the schematic in the description of the rear wheel removal section shows the sprocket side.

I think it may be missing a spacer.

Is it possible that a missing spacer could have been compensated for by tightening the axle bolt enough to bend the swingarm in?

I believe it was not overtightening but rather the forgotten spacer that surfaced. That would be until the problem was noticed, probably in the form of rear thrust angle pushing the bike in a scary manner and after a realization or connection was made to the sound, noise, or sudden sluggishness at low speed. And then the problem was "fixed."
I need to contact the "friend" who witheld this bit of information.

the bolts are OK. missing the spacer. be aware that there are TWO on the drive side.... the other one is in the cush drive. get the wheel off & the cush drive pulls straight out.. the 2nd spacer fits between the two bearings.

item 42036

Yeah... one rule of thumb- pay attention to the tightening of your castle nut. Not the actual count of threads, but rather, the orientation of the cotter pin hole in relation to the slots in the castle nut. You can see from the pic that the nut is over-tightened and the cotter pin is nearly outside the slot.

This little tidbit allowed me to notice that my wheel bearings were failing on my TAT trip this summer.

Also- looks like the chain could use some maintenance.

Thanks for all of the insight.
I was confused as to how this could happen in in its current configuration. I will be getting the wheel off soon and I will report back with what I find. Always good to see answers and to have a searchable topic.

The swing arm is trashed.

I would not ride it until I either had it welded with a brace or else replaced it.

92143B is the part that was missing that caused the nuts to grind the swing arm. The fact that the cotter pin/slot looks funny (as noted by Dirty Dog) is a strong indication the the spacer in the cush drive is missing..... thats why the nut goes so far down the axle threads (and the axle can go in from either side... I put mine in from the brakes side, easier to align the caliper, etc.).

the inner bushing is easy to lose when the wheel is off, like during tire changes.... how do I know these things.

You know, I cuss and grit my teeth every time it won't line up properly, but I've never once considered putting the axle in from the opposite side.

I don't have a motorcycle lift so I have decided to make my own out of an old jack. Progress has been delayed. Pay day is Friday, so if you are paying attention to the thread you will have to wait for a few days.
Pictures of all will be included.
