Snapped Studs
 

Currently faced with this, can anyone point me in the direction of a suitable stud extractor to have a bash at getting these out? Shall subject it to some heat cycles and penetrating fluid.

Not fun.

My opening thought would be that if they were stuck in the threads good enough to snap off, then they are probably going to snap off flush with the head if you get anything else on them.

Last time I was faced with this I just bit the bullet, pulled the head off and took it to a local engineering firm who removed them without too much trouble.

When those nuts don't come off easily I just cut them off and save the stud.

They were just cap head bolts, not actual studs. Extractor might be worth a try if they snap further in its less to remove :)

Ah, pointy, yes the curvy has nice thick studs and nuts which can be cut off.

I'd be soaking in your penetrating oil of choice often in advance.

stud extractors are notoriously problematic, they tend to snap. then you have the fun of trying to drill out hardened steel.

Personally I would remove the head so that it can be properly lined up to drill out the broken studs (with a left handed drill)

Don't bother with easy-outs there - or anywhere else for that matter.

I've had decent success with the socket type extractor, like this. Better than the cam type IME. In any event the cam one won't fit in that space on the right of your pic.

A bit of penetrating fluid - probably useless as it's not easy to make it run uphill but it makes me feel better.

Also gave mine a blast with a can of freeze spray first and they eased out with the extractor. Make sure the extractor is fully on the stud and go easy.

If that doesn't work it'll probably need drilled out.

Thanks guys, yes plusgas on the case. It was the socket types I was thinking so shall check them out. Might see if can get a nut welded onto the end. Bloody pain in the ****!!!

Finally got the exhaust off the bike at least so will be able to get the swing arm bearings done. Just need to sort the studs. Is the gasket visible in the picture below? Should I replace it with a new one or see how it goes once re fitted? The brackets mounted to the pipes that attach under the engine are gubbed what do people generally do to replace the nut and bolt arrangement under these?

after trying very unsucessfully to drill out, i wouldnt recommend. try moled grips with heat and it not get a welder to weld something on to turn them out as normal?

I helped Winder do his the other week. The studs snapped off as yours did. We successfully managed to drill them out, steadily increasing the drill size & removed the old stud. Cleaned the thread up and put new ones in.
It takes time, patience and having the right tools for the job.
