Rear wheel flange crack

[igoldin74]

I was preparing my wheels to get powder coated. When I cleaned and degreased them I noticed a a tiny crack one the rear wheel flange from the side where hub is attached. I am not sure if the crack is just a result of steel axle sleeve being pressed into the wheel or it?s a damage or a defect. The bike has about 40?000 miles on the odo. Has anyone seen something like that before?

That's alarming! I'd be looking for another wheel, myself.

Agree. New wheel time. Bummer.

Is this on your 650? If so, is it a G or an L? I happen to have an 82 650G roller in the garage. It's pretty well picked over, but has wheels and a few bits left. If you don't already have a source for another wheel, and you're interested in this one, let me know. I have one from an 80 850G that is a slightly different design but same size that I can trow on the 650 so it'll still roll. It will take some work to get things swapped around since the 80 wheel doesn't have a tire on it. Anyway, if you need the wheel I've got some time this week to shuffle this stuff around.

thank you, Unfortunately friggin? flickr wouldn?t give that option to get the code snippet while on a mobile browser and I don?t have access to my PC at the moment.

 

[igoldin74]

It?s 650G. Where are you located?

You bet.

I still don't understood why Flickr does that.

I'm in Albuquerque, NM.

Shipping won't be cheap for this, as you know. Ebay has some for pretty cheap. One in Michigan for $35 and free shipping HOWEVER it says it's a 16" wheel so it may be from an L model..

Hope you find something.

That wheel is scrap I would not want to ride on that time to look for a good one good luck

Thanks to all who responded;
So, I ordered a 'new' (another) wheel, which, as stated, was from bike with only 4k miles.
The new wheel has a same crack in the same area. Is that just a production flaw? It looks like the 'crack' or rather slight separation is where still sleeve joins the aluminum wheel body.
GS650 flange crack wheel #2
GS650 flange crack wheel #2

That new has definitely less miles than mine, the wheel hub teeth prove that:
My old 40k mile hub:
Suzuki GS650 rear wheel hub

The new hub:

Test the metals on eac side. I thought it was a joint. A drop of muriatic acid maybe?
Metals look dissimilar
Maybe the wheel side gets rolled over the insert during final machining

This has made me take a closer look at the wheels I have here, igoldin74. This '80 850G wheel has that same cracked appearance.

Rotating it around though, I can see indications of it just being a metal plating that's worn or chipped off. There is no crack.

I'm so sorry I didn't simply look at it before.

Say, you mentioned that new spline joint come on the extra wheel you ordered. If so that alone made it worthwile.

Thank you for confirming @Burque73

The hub is pressed into the aluminum wheel, then the wheel and hub turned together. What you see is the mating seam of the two different metals. JMO Was a machinist for 30 years. The second and third picture show the alignment tooth of the hub.
