higgzGU! Posted May 17, 2008 Report Share Posted May 17, 2008 (edited) hi there,I have a problem, I have the back top right 4 bolt mount bolt is stuck in, i tryed it loosen the bolt and unfortunatly the bolt snapped and a bit is still stuck in the frame with about 5mm sticking out of it. This happened to me on my old czar frame and i would like to get it out due to i am wanting to build up a second bike with it.I already tryed to heat up the bolt and saw a line in the bolt and then tryed to turn the bolt using a screw driver but it would'nt budge.If anyone has any suggestions for how to get the bolt out all suggestions would be greatfully appresated.Many thanksCraig Edited May 17, 2008 by czarcraig Quote Link to comment Share on other sites More sharing options...

Scott Norman Posted May 17, 2008 Report Share Posted May 17, 2008 Well you could drill the bolt and then re thread it but the only problem is you will have to use a larger size bolt. Hope i helped.Scott Quote Link to comment Share on other sites More sharing options...
MadManMike Posted May 17, 2008 Report Share Posted May 17, 2008 I was gonna suggest the screwdriver trick but you've already tried it Cover the whole bolt area in WD40 leave for 5-10 mins to soak in, tip boiling water over it and try again? That's what I did to get a bolt off my rotor. Quote Link to comment Share on other sites More sharing options...

The Stig Posted May 17, 2008 Report Share Posted May 17, 2008 A couple of ways;-Scredriver (as suggested)-Blow torch to expand the metal then un screw out (combination of the above)-Drill out like 2 mm smaller than it and take the rest of the metal out-Drill it out to same size, Tap then helicoil!Tom Quote Link to comment Share on other sites More sharing options...
Captain Scarlet Posted May 17, 2008 Report Share Posted May 17, 2008 (edited) -Drill it out to same size next size up, Tap then helicoil!Tom Edited May 17, 2008 by Fugley Quote Link to comment Share on other sites More sharing options...
The Stig Posted May 17, 2008 Report Share Posted May 17, 2008 If you were to drill to a size up then tap you wouldn't have a thread for the helicoil! So 5mm drilled to 5mm then tapped to 6mm helicoiled to the 5mm Tom Quote Link to comment Share on other sites More sharing options...
Ryan Blackwell Posted May 17, 2008 Report Share Posted May 17, 2008 use a table vice clamp the bolt end as tight as possable and spin the frame around Quote Link to comment Share on other sites More sharing options...
Echo-Scott Posted May 17, 2008 Report Share Posted May 17, 2008 Drill a small hole down the middle of the bolt, then bash an allen key in, then turn and that might work. Or take the frame down to mine next weekend and I'll do it for you. Quote Link to comment Share on other sites More sharing options...

Fish-Finger-er Posted May 18, 2008 Report Share Posted May 18, 2008 mole grips, if that dont work, cut it off flush, easy out, and appropriate sized drill.failing that, drill it, and tap it. and if you need to go to a bigger thread, helicoil back down.

otaylor38 Posted May 18, 2008 Report Share Posted May 18, 2008 weld another bolt onto the bit that is hanging out. then you can unscrew the bolt that you have welded to it and the one that is stuck in should come out. try not to weld it to the frame though for obvious reasons lolhope that helped Quote Link to comment Share on other sites More sharing options...
forteh Posted May 19, 2008 Report Share Posted May 19, 2008 Betting its a stainless bolt and you didnt use any antisieze on it? If it is stainless then you will have a right game to drill it unless youre set up properly (pillar drill and some very sharp, tipped drills). The reason its seized is because the threads have galled and picked up on the aluminium, effectively cold welding the 2 together (happens even easier with ti bolts) - a tiny smear of copperslip will stop it happening.My method of attack would be mole grips bollocked up tight onto it and very gently heat the aluminium with a blow torch, you need to heat the frame up quicker than the screw so try not to use the heat for a long period at a time; if necessary let it all cool down and try again. Gently apply pressure to the screw (anticlockwise ) whilst heating it.If that doesnt work then I would take it to a local engineers and ask them nicely to drill it out and/or helicoil it Quote Link to comment Share on other sites More sharing options...
tarmacterrorist Posted May 19, 2008 Report Share Posted May 19, 2008 dude, if some of these ideas seem a little much to handle urself, just take it to ur local engineering firm who'll be happy to solve it for you D... Quote Link to comment Share on other sites More sharing options...
