Sheared Exhaust Stud in Cylinder Head

After today's performance of removing the cat bolts I thought the header nuts would come off easy enough. Well, 3 of them did and the last one sheared part of the stud off despite WD40 and tightening loosening motion etc.
Fortunately there is a threaded bit about 15mm long sticking out. I could attach a couple of nuts to it and maybe withdraw it afer soaking in Gunk penatrating oil and applying heat. Or shall I wheel it round to a garage for the stud extractor treatment?
Bugger.

Those stud extractor socket things work well and they're only a few quid. Bit of a bitch though - good luck mate

oxy-aceteline is the answer.

Hey Julian,
Did the stud extractor socket that I gave to Paul work?

Julian mate
If you want another stud bolt to replace that busted one, then PM me your address (again!) and I'll post one on

Thanks chaps
Bob - I've just tried your extractor. It's the corect size for the stud, but because the stud is in the recessed manifold section it is just a fraction too big to fit in.
In the mean time the stud is being soaked in oil, twatted periodically with hammer and heated.

You did say there was a section sticking out....yes?? Well what about a set of mole grips that could lock down onto the part then try and persuade it out?? Just a thought.

AH!!! Mole grips.........Now your talking!!! if they slip, 14" stilson wrench may be the answer

Nothing to do with your sheared stud but I remember you asked about the terminals on the PC680 Hawker battery - Looks like they sell them for £6

There was a pair of these with each of the batteries I bought/supplied a little while back. I didn't use them, as you only need to bend one lead, so I'l see if I can find my pair, or Paul or Harry may have some. £6 seems a bit steep.
Cheers

Thanks Alan.
Appreciate it - can I trouble you to bring one to the next Sunday run?
Jason
As for the stud I think the remaining bit is not going to budge. Would hammering a scredriver blade between the stud and manifold to provide a decent force fit be an acceptable bodge to you?

I'll have a look in the garage tonight. If you need them in a real hurry I can post them to you.

Sounds good to me mate! I had to do this the other day with the little 5mm feckers holding the front ABS sensor on. Had to cut a little groove and use a screwdriver but unless the groove is deep, the edges just bend away with no movement from the bolt. I ended up with a pair of moleys

holding the screwdriver when I forced myself against the wall of the garage and applied max pressure to the screwdriver, all whilst perced with the bike on top of the bike ramp 2ft in the air

When it moved though.. joy unbounded! Still wrecked the ABS switch though
Trouble it, if it all goes Pete Tong, then what do you do? You might end up having to take the flippin cylinder off. If it all goes tits though, we have the spare technology in my garage

I'm not in a hurry so have just bought some Plus Gas to be applied over the next few days before the club hammer is unleashed.
