removal of exhuast stud

[gordon]

hi guys dose any one know of a easy way to get a exhuast stud out , its not broken as such cos someone put a


bolt in and the head broke off  ? :'(


thanks guys

[dickturpin]

can you get two nuts threaded onto it then lock the two together and turn the innermost one?

[markbubble]

as already mentioned try getting a couple of nuts on it or just one and weld it on,before you try to 'undo' it get some heat in the area withh blowtorch or similar

as above,as above

I had a broken stud, but it still had some thread on it. Rather than attempt to remove it I had a sleeve nut made (from a hex nut). It fitted through the header flange on the downpipe to secure it. See the links for pictures...

when using the 2 nut method as described above also try screwing the bolt in then out and soaking with penetrating fluid 
if you have no luck and before you shear the bolt off flush you could try my method below it sounds like a bodge but has worked in the past.
the biggest problem with drilling out a bolt/stud is keeping things straight and drilling down the middle so heres my bodge.
get 1 m6 sleeve nut or stud connector nut or what ever you want to call it, basically its a long nut approx 15-20mm long,
now find a brake cable adjuster from a bicycle these are m6 thread with a 3mm hole down the middle
now buy a GOOD quality 3mm drill bit .
now you are ready to attack the stud
screw the nut onto the broken stud, screw the brake adjuster into the stud, now drill take it easy and apply cutting oil/lube
with any luck you will now have a 3mm hole down the middle of the stud
you can now use larger drill bits until you get close to 4.8mm ( the thread tapping size for M6)
if you get really luck you maybe able to pull/pick the old stud out of the engine case with out damaging the thread in the case
hope this makes sense

thanks guys i,m going to try the two nuts way first but if the wont work,


cnw180 what size bolt was it made from and size thread  put inside please ?

[Andy FZS]

I have a stud extractor it has a hole the stud goes through and then a cam that closes the hole tighter the more you pull. Someone near you may have one you could borrow perhaps

i think welding a nut onto the stud works the best

[gordon]

hi guys just an up date the two nut way did not work , so i got a bloke at work to make a bolt with the right

size thread inside it so now all i have to do is get it through the hole that holds the exhuast on then job done


the second easy way with help from you guys , thanks for this forum




thanks guys will keep u updated  tomorrow

Sounds like you're sorted then. I think the bolt I had made was an M6 thread, or whatever the standard stud nuts are!!


The hex nut was around 20mm I think, and around 15mm was ground away to allow the bolt to slip through the downpipe header flange..
