Really random question but im trying to get my sub-frame off of my kxf and there are 2 allen keyed bolts i just cannot get out, they are just so tight, i' ve been covering them with gt 85 for 3 days, dont want to snap them or anything as i need it off and welded before this weekend, any advice? Cheers
no it hasn't been rounded off yet, knew not to risk it as I rounded a 10mm bolt going through the sub frame via the exhaust bracket, had to smash a 9mm socket to re-carve it; turns out just by smashing it loosened it off abit and I was able to just about get it turning with a pair of pliers then wound it out
I'm definitely dipping every bolt on my bike in a bit of copper grease before I put it back on from now on
Go to halfords and pick one of these up. One of my favourite tools in the garage.
You fit the allen head in. And smash the hell out of the wrench with a hammer. The force generates a twisting motion that uses massive force but only a tiny turn to undo bolts. Saves rounding heads.
Just go for it, if it snap's you have just released the tension and it will come off very easy with a drill and small drill bit turning the way the bolt unscrews
Don't think you can round off an allen head unless your using the wrong key.
Only gone and got the fkin bolts out aint i? I smashed the s*** out of the allen until the allen key snapped, then i put a mole grip on the bend of the allen to use as a lever; it could support my full body weight :/ so i leant on it with a straight arm and lightly bounced until it came free!! Hurrah!!!!
Life lesson; copper mother fkin grease on every bolt before fitting back on the bike
+1 for tapping it with a hammer. Put allen key on said bolt's then just tap the hammer, if it doesn't go after a few taps give up, or you'll do the head in.
