Broken Bolt/stud

[zx81]

Hi all

I'm wondering if any of you knowledgeable people can advise me on a small problem I have, I was removing the Exhaust from my bike .. there was one nut which was rounded I eventually got a socket on it and when I tried to remove it it completly sheared off

now this "bolt comes from the engine and goes through the ring that holds on the exhaust and then the bolt goes onto the thread, now if it was just a bolt I could use a bolt extractor/ drill it out helicoil it.

but what do you do in this situation?

is this "bolt" / a threaded bar that is threaded into the engine or is it wielded onto the engine.

any advice would be appreciated.

cheers

It'll be a "stud" - a short threaded bar, usually with a section in the centre with no thread. They're a common problem sadly.
If it's really stuck fast, you, or someone that you pay to do the job, will have to drill it out.
try a search for "exhaust stud" or "exhaust bolt", there are a few good threads with some sound advice. Someone...."Pete" I think....did a post recently on how to get one out and Stinkwheel describes how to drill them out with a guide.
If you don't feel too compitent with a drill, I would advise that you get someone who is to do it - the broken stud is harder than the surrounding metal and the drill will veer off very easily. I've seen some real butchery in this dept.
When all done, use deep-domed nuts as they don't seize as easily.

I assume it's snapped flush with the head?

ahh Thanks Vincent .. been doing a bit of googling I see there are some tools for removing it if there are some threads showing.

I would use wemoto - they're listed as exhaust stud and exhaust stud nut.
I weld some mole grips onto the protruding tip and just twist them out - you could try soaking it in a penetrating oil (ideally for as long as you can) and getting a pair of moles on there.

If there's only one thread showing, I reckon it'll have to be drilled out

I understood it as only one thread on the snapped bit?
