Bionic Balls Posted August 1, 2005 Report Share Posted August 1, 2005 drilling a hole in it is the best way....so try again :-" otherwise..araldite-ing an old allen key in seems to work sometimes (Y) adam Quote Link to comment Share on other sites More sharing options...
The Dude Posted August 1, 2005 Report Share Posted August 1, 2005 sounds like youve mangled it, so araldite in an old allenkey, put a pole on the end and heave. kettle full of water on it normally helps unsiese the welded thread, or some liquid wrench, WD40, anything that will lube it, cover it in it and let it soak in. mole grips, hacksaw a slot in it and turn with a screwdriver (wont work if cranks in the way). couple ideas to keep you going.

Damon W Posted August 1, 2005 Author Report Share Posted August 1, 2005 cheers im gonna go get me: a left hand tap and boil water over it, and try and rip it out with a drill (Y) :- Quote Link to comment Share on other sites More sharing options...
Sponge Posted August 1, 2005 Report Share Posted August 1, 2005 Damon, another idea is that you could get a hacksaw and sort of make a line in the crankbolt side, the bit that is supposed to touch the plastic washer... sever a line on that bit of crankbolt... *** a screwdriver in that line, and hammer... This has worked for me on a loctited rounded Crankbolt and Disc rotor bolts... (Y) Hope this helped :- Quote Link to comment Share on other sites More sharing options...
Waynio Posted August 1, 2005 Report Share Posted August 1, 2005 weld an old 8mm allen key to it and get it off that way. trust me if its ISIS we have had a few of the Truvativ ones in particular (bolts & b/:D get stuck even on XC bikes (Y) :- and the best way is to weld an allen key to it and then get it off that way.
