Your valued opinion please! Can I still ride with this broken?

[oldskool]

Okay so the sprocket bolts unwound for the 3rd time, even with loctite on. This time I was not so lucky, one of the bolt holes in the wheel hub cracked off. Is this still rideable or should I get it repaired first.
If I need to get it repaired what is the best way. If I need to replace the wheel...does anyone have one sitting in their shed?
Your 2 cents worth appreciated!!!

Personally I would get it fixed. What if you were belting along and the back locked up?

There are wheel repairers like this guy:

You may find it cheaper to get a used wheel from a breakers if they are a common size.

KTM have owners clubs all over the world, maybe its worth going online to see if they will help.

Looks like it was overtightened. Also, why weren't you using lock nuts?

? Not even worth answering this!

it will fail soon anyway, and the only repair from here is replacing the hub, it may be worth the risk as i do not think it will do any more damage if it fails,

Yeah it will probably fail tomorrow halfway up one of those hardish hills you described!!

It was suggested the problem is vibration resonating through the light rear sprocket that shook the nuts loose. I am inclined to agree as the problem seems to have started after a new sprocket was attached.
Nuts and Bolts from Cycletreads, I wonder if I should have got a different brand?

Those nuts and bolts don't look like the right ones.

1.what is the blue stuff?
2.what kind of locktite are you using?
2a.how much of said locktite did you use?
3.did you clean the nuts and bolts with contact cleaner before applying the locktite?
4.did you change the sprocket or are you refering to the newish one that was on it when you bought it?

[oldskool]

Let's make this clear seeing as everyone is looking at how it happened instead of giving advice to what to do now.
What you see now is not what I initially did before the breakage. This is the end result of frustration. Look carefully. You will see the proper nuts underneath the unconventional 'lockingnuts' which I have yet to try .
If I recall the nuts were loose when I bought it.

If its blue loctite, you'd wanna use red

This being the case, the bolts will likely now refuse to sit tightly in their holes, no matter how tightly you do them up. Double nut or locknuts won't do jack, as the real issue is the sprocket moving on the hub. No amount of force holding the sprocket on will resolve this.

In answer to your question, yes you should be able to ride it, but you will have to torque-turn everything properly with bolts that are just the right tensile strength. Too soft and they will just break, too strong and they will mash the hub or sprocket without entering their elastic region.

Worst case, you will have to replace the bolts, sprocket, and hub.

Thanks Steve, very informative, new bolts and damaged sprocket not bedding was something I did not realise, ...makes sense though!

id still fell comfortable riding with the hub like that : check the sholder legnth of the bolt, if its even a fraction too long it wont tighten up properly ( it will seem tight, but it wont be), also check the taper on the head of the bolt compared to the taper on the sprocket, if they are aftermarket bolts i would try to get some genuine bolts( there may be a slight difference in the angle of the taper)and like every one has said, use the red loctite, i use the stud-locker one not the thread-locker one. as for repairs, id say find another hub, in my experience fixing/welding cast alloy is difficult and results vary, especially on areas were high loads are exerted on the welded area.

Hi Steven,
Yes I am tempted to ride tomorrow. I used to ride a XR500 with one of the hub mounting holes broken, it wasn't an issue but that sprocket was a solid beasty which was more or less seized permanently onto the hub until you fair whacked it off with a mallet.
I wonder if fabricating up a 'C' shaped bracket and drilling holes in it that matched say 3 of the holes in the hub. Placing this over the offending breakage should reinforce it and provide a support for that bolt that goes in the broken hole wouldn't it?
If I rode tomorrow, you reckon I should remove the dodgily mounted bolt? Should it slip off it may damage my swingarm more?

[krad_nz]

I accidentally over-tightened, then snapped off one of my rear sprocket bolts. Given that I wanted to ride, I removed the damaged bolt and double checked the rest of them were on properly. Then went for the ride anyway :P
I got away with it in this case.,
