I know this is the 7th page and its been likely said but my best way was always to drill with a thin bit, maybe a couple mm. Once youve drilled it a bit then hammer a torx into it and loosen. Hammering not only give it a torx head but also shocks it a bit to help loosen.
True, 7th page. But if you spend any time at all working on mechanical stuff, (not just bikes) sooner or later you're going to be faced with a seized thread and I bet I'm not the only who has learned something from these posts. Cheers, Nick.
The bolt in question goes into a well nut which has seized to the bolt and is just spinning now, I had the same problem a while back! Pliers on the well nut and Allen key with a bit of WD40 to penetrate job done
Those Well nut's are a pain. The one I had seized, I managed to get hold of it with the aid of a small boy with little hands (11 year old Son) and water pump pliers. and get it free. I put a new one in covered in the medicinal tincture, Copper grease. Mike.
Just to close this one out, I can happily report back that I managed to get the bolt on question out this afternoon. And the winning method was.... Torx socket (of larger size than I owned previously) and a bit of gentle persuasion! Tried dremel but got scared when sparks started flying, and (thankfully, it seems) didn't need to go as far as the extractors or the left handed drill bits, all of which I now own having received from Santa! Bad news is that because I can't ever seem to leave anything alone unless it is 100%, I may have to get the bolts out again soon (made sure I greased them this time though)
I have the same misery going on with the bolt that holds on my hugger, the one in the middle... Cant get anything in there... Shock is in the way to be able to try and hammer a torx bit in... No room for a drill... Resided on the fact that I'm actually gonna have to take the whole swing arm out just to tackle the little blighter !
Make sure you have a decent set of Allen keys as cheaper ones can be a fraction out and cause the inside of the bolts to round off,and change any bolts to stainless,especially the small ones as these seem to be the ones that corrode quickest.
Good advise gents on how to remove the said offender. I am a Survival Craft Tech and come across seized bolts an a regular basis. The most precious tool in my toolbox is the impact screw driver. Gentlemen add this to Santa's list this year and you won't strip another bolt head again. (Maybe)
take the shocker out. its a piece of piss, and at the same time check/clean/ grease bearings and likages
