so, one of mine has decided its no longer attracted to its thread... I have some new studs sitting here which are obviously left hand thread, and the botl 'head' it riddiculously small.... so any advice from anyone on the easiest way to remove this without burning all the paint off my hub with a blowlamp? ive already cracked one (cheap) socket, Im thinking its probably easier to cut the head and thread off flat with the hub, the drill though it and use a stud extractor - but then being a left hand thread that wont work will it.... aaargh!!

Cheers!

Grind a 6 sided socket flat on the leading edge "should be a 12mm socket", it then gets a better grip on the Head of the hub stud......the socket has a small shamfer on it if you look at it from the business end, once ground square it gets a good grip.....Thats what ive done....

so........
I ground a thin 12mm socket down to get rid of the rounds, and cleaned all the paint off of around the bolt head (and what was stuck in the other side), chocked the now dismantled hub in the workmate and set about undoing the bastuard using a nice long torque wrench to give extra purchase - no dice, head rounded off. >:(

then next I welded a succession of bolts/nuts (5) to the head and managed to get it to move about 0.5mm before each one broke off.

so I tried a new plan of attacvk - cut the remains of the stud off flush ont he other side and drill a pilot hole in (but not quite all the way just in case I need the head) then up to 5mm and try a stud extractor (if you go from this side then doing the extractor up undoes the stud or at least should...) and guess waht - no suprise really, the extractor snaps off in the hole.

So now my plan is to ignore it and hope it goes away all by itself... or give it to somebody who can remove it for me for a fee. Any ideas?

ha ha 5 minute job m8 ive had days like that good luck

Soak the stud with diesel or wd40 cut a slot in the head, with a dremel. Impact driver and good fitting screw driver blade, bang and out she comes!
Cheers Rick.

Its a left hand thread.....You turn it clockwise to undo..as if you were tightening it.....

ad same prob other week took it to my mate waddo welded a nut to stud gave it some heat sorted

well what a great little job this turned out to be - NOT!

I managed to get the broken stud extractor out by drilling from the 'head' side and then drifting it out, I then drilled out to leave about 1mm of the stud in place and attempted to remove it again with a larger stud extractor - no dice again (this mo fo is welded in place!) and then a nice crack appeared so now I still have a bit of stud in place and a crack So it needs welding and helicoiling.... Dont suppose anyone has a window side disc housing spare? Or knows anyone that can weld the crack and install a left hand thread helicoil?

^^^ OUCH ^^^
