Alouette3 Posted January 12, 2015 Posted January 12, 2015 Apply heat with something like a soldering iron. Loctite breaks down with heat. Make sure you have a decent allen key so as no to mess with the head. Use a lever to help if you can't get the allen key to budge, I sometimes use the back of a pedal spanner for extra leverage.
NukeproofPeanut Posted January 12, 2015 Author Posted January 12, 2015 Use a hair drier first. So I actually used a hair dyer this afternoon to heat up the frame to remove a stubborn bearing I had been battling with for a while. I subsequently had the same idea for the bolt, but alas no luck I'm going to give the soldering iron a shot, should better help focus the heat! Nice idea!
droo Posted January 13, 2015 Posted January 13, 2015 As a last resort, if you strip the hex, an EZ-out will do the job. You can get new bolts from Giant. One thing nobody's mentioned yet - make sure you're trying to unscrew the 5mm bolt and not the 6mm one. The 6mm is the shaft that goes through the entire bearing and shock body assembly, and if your bearings are seized you'll be adding the breakaway force from this to an already tight bolt. Good luck.
Mawbs Posted January 13, 2015 Posted January 13, 2015 might be a stupid comment but have you let all the air out of the shock
SwissVan Posted January 13, 2015 Posted January 13, 2015 No the nut is still in place. I just can't loosen it. The other lower one that connects the linkage to the rear triangle came off with ease. The frame is completely disassembled, with the rear triangle off. This is the last piece i need to remove and the shock will come off. might be a stupid comment but have you let all the air out of the shock Good point, except if I understand it correctly it is the NUT that wont loosen. Ideally the OP needs to loosen the nut (turn it anti clockwise ) and not turn the bolt (just hold it still). If that doesn't work try turn the nut very slightly (tighten) in the other direction (CW) to "loosen / break" whatever is causing it to seize. Failing that and IF the bolt can be turned it might be worth trying to turn both the bolt and nut at the same time (loosen...anti clockwise) but be careful not to let the tools slip and wear the bolt head and nut round. Good quality tools that fit properly are important. After this the impact option might be needed in conjunction with some spookpiss or mousemilk dribbled onto the bolt threads at the nut side and give it time to penetrate / work its magic After this failing all the above...hacksaw blade, sharp chisel and hammer to split the nut...be careful to not slip and moer the frame This Not this
droo Posted January 13, 2015 Posted January 13, 2015 Spookpis will unfortunately do nothing in this case, that bolt's loctited in place. Splitting the nut won't help either, there isn't one - it's a bolt that threads into a shaft. Heat and domkrag are the only things that'll help here. An impact driver with a 5mm hex bit has the best chance of releasing it.

NukeproofPeanut Posted January 13, 2015 Author Posted January 13, 2015 Yip thats correct, although thats the shaft side, the nut is on the drive side, but looks the same.
SwissVan Posted January 13, 2015 Posted January 13, 2015 Ja good luck hope you come right... it might pay to lubricate the threads partially when u reassemble everything, leave the end threads dry so you can put some a little bit BLUE Loctite on them to stop them coming loose. Chances are the problem is due to corrosion (dissimilar metal?) aided by water and not the Loctite.Unless it was assembled with to much Loctite, this is what they say about the blue stuff removal
NukeproofPeanut Posted January 13, 2015 Author Posted January 13, 2015 turning it anti clockwise right?tsek!
