Shez.sheridan Posted July 11, 2006 Report Share Posted July 11, 2006 Right,I've been waiting weeks for my new ti forks to arrive. I cut the steerer down, built my steed back up & within half an hours riding, I fell off a tree (there was a sort of hurricane here 2 weeks ago, so some big 70ft monster trees are down ) & snapped 3 spokes on my front wheel; all disc side - nice job Dave.So, now I have to remove the disc - problem is though, neither I nor the Italian guy in the bikeshop could remove the torque bolts due to the fact that they've probably been loctited to death before I bought the bike.So, Mr I-tie suggested that I should go up the road (always somewhat further than it looks on his dodgy map on a scrap of A4 paper), and speak to the guy who owns a blowtorch..Now, I like thew idea, pure & simple - but a bit on the brutal side perhaps..as I'm sure Mr Monty/Myself wont be too happy when the disc/hub etc become discoloured & damaged (I expect) from the heat..Things that would take one hour in your local bike shop, seemingly take days if not weeks over here - Tis a tad frustrating as I've rode 1/2 hour in 6 weeks..So - To blowtorch, or not to blowtorch...that is my question?Derv Quote Link to comment Share on other sites More sharing options...
Lawnmowerman Posted July 11, 2006 Report Share Posted July 11, 2006 Smack the head of the bolt down and it should brake the bond. Quote Link to comment Share on other sites More sharing options...
Sam Nichols Posted July 11, 2006 Report Share Posted July 11, 2006 There are alternatives;You could drill the bolt and then use an easi-out.You could use some mole grips to grab the bolt and then loads of leverage to undo it. Quote Link to comment Share on other sites More sharing options...
Danny Posted July 11, 2006 Report Share Posted July 11, 2006 P.s. There Torx bolts Quote Link to comment Share on other sites More sharing options...
Krisboats Posted July 11, 2006 Report Share Posted July 11, 2006 Get a torx head, the ones that fit into most multichangeable screwdrivers etc and place it into a ratchet.... stick a long solid pole on the ratchet and use the pole tp lever the bolt undone. I'd like to see any torx bolt that can withstand being twisted with a 6 foot pole for leverage.Mine were in a bit tight too, i just used a screwdriver to get mine off (one with the multichange head fitting) and i managed to bend the torx head so it spiralled instead of being straight all the way down. Got the bolts undone though. Quote Link to comment Share on other sites More sharing options...
dave33 Posted July 11, 2006 Report Share Posted July 11, 2006 heating them up is the best bet to be honest just be careful woth the flame and let it cool naturaly after you get them out Quote Link to comment Share on other sites More sharing options...
Shez.sheridan Posted July 12, 2006 Author Report Share Posted July 12, 2006 I have used a 'Torx' (sorry..lol) tool, and so has the bike shop, but the tools have just skipped out of the bolt, damaging tool & bolt every time we tried..Does pouring a kettle full of boiling water over it help...I know it has worked for some people, but it's sods law it won't work for me..I think its worth a go though, as I think a blowtorch is better as the last resort?Derv Quote Link to comment Share on other sites More sharing options...
ScotchDave Posted July 12, 2006 Report Share Posted July 12, 2006 The best and most foolproof way in my experience is: take a file to the heads and file spanner flats on, then use a shifter and unscrew em. Tapping the bolts with a hammer, tapping not walloping, and pouring boiling water onto the bolts can also help as they will break the loctite bond. Good Luck. I find the best way to try is: torx key, spanner flats, if those fail go to the drill and the eas out. Quote Link to comment Share on other sites More sharing options...
blinky Posted July 12, 2006 Report Share Posted July 12, 2006 hacksaw a groove in the bolts, then use a flathead screwdriver to get em out. Quote Link to comment Share on other sites More sharing options...

Krisboats Posted July 12, 2006 Report Share Posted July 12, 2006 (edited) Oh i just forgot to mention what my mate jay did to get his old rotor off. He got an angle grinder and very carefully ground off the heads of each and every bolt on his rotor... only skimmed the rotor once so if you were careful you could easily do it without marking your rotor.Once the bolt heads were all off he lifted the rotor off and got some mole grips onto the little bits of bolt that were lift still sticking up... and they came out so easily. The heat from angle grinding them had loosened them up and a couple were easily taken out by hand without the need for mole grips.

Ash-Kennard Posted July 12, 2006 Report Share Posted July 12, 2006 why do you need to take the disc out to replace some spokes, i must be missing something. Quote Link to comment Share on other sites More sharing options...
Egg Fried Rice Posted July 12, 2006 Report Share Posted July 12, 2006 (edited) problem solved for everyone with rounded off bolts etc etcthese babys will solve everythingknown as superwrenches, you should be able to get them off ebay, kelkoo etcmy uncle uses these on rounded bolts. anyone that knows about these will know how useful they are.they can unscrew/undo any stuck bolt/screw of any kind. i highly recomend in buying these.JK Edited July 12, 2006 by J-KAY Quote Link to comment Share on other sites More sharing options...
Savage Posted July 12, 2006 Report Share Posted July 12, 2006 I've had the same problem in the past. Drill the heads off - remove the disc - grip the stud left behind with mole grips. It works and only costs the price of six bolts.Ben. Quote Link to comment Share on other sites More sharing options...

Egg Fried Rice Posted July 12, 2006 Report Share Posted July 12, 2006 Cool, not gonna work very well on round headed bolts then? thats the whole idea of them. they undo rounded off bolts etc. made for round tubing i.e plumbing. i use them all the time. it helped me get out rounded shagged bolts out from the bashplate and loadsa other stuffJK Quote Link to comment Share on other sites More sharing options...
ScotchDave Posted July 12, 2006 Report Share Posted July 12, 2006 (edited) No, no no, the round bolt heads, as in the ones which have a concave head on em, like an upside down bowl, there'll be no way for them to get a grip.. EDIT See, no way to get a decent grip. Edited July 13, 2006 by div Quote Link to comment Share on other sites More sharing options...

manuel Posted July 13, 2006 Report Share Posted July 13, 2006 " When in doubt, Burn the bugger's out"- blowtorch Just be careful.On a serious note, I think the cutting a slot into each of tyhe heads and being very careful use a screwdriver to get them out.If you cant get em out with the torxbolt fitting youll never get em out with a screwdriver ...Drill the top off then use those superwrenchy things or molegrips Quote Link to comment Share on other sites More sharing options...
