Greg29 Posted July 23, 2012 Posted July 23, 2012 I need some some tips on how to unscrew a seized pedal without wrecking the wole lot. I have applied some Q20 with brute force - but maybe just not enough????? Oh, and yes I am turning it the right way - reverse thread. Any tips welcome...
covie Posted July 23, 2012 Posted July 23, 2012 pedal wrench with a rubber mallet, two or three taps and it will be sorted, if not the right sized spanner with a hammer should sort it as well.

Any tips welcome... small butane blowtorch, (cape union sells a nifty lighter/blowtorch) apply heat to crank close to spindle. spray some more penetrating oil onto the thread, heat again and try to loosen as normal.

V12man Posted July 23, 2012 Posted July 23, 2012 Supporth the crank with some wood under where the pedal screws in - Take the rubber off the pedal spanner and wack it (the pedal spanner) with a 3 - 5 pounder - not took hard, its the shock that loosens it. If you don't support the crank arm, the flex in the crank arm will make this ineffective. Put anti-seize on the threads when you re-assemble.
kosmonooit Posted July 23, 2012 Posted July 23, 2012 Can you sacrifice the pedal? If so, dismantle it and use a bobejaan spanner on the shaft Also might look at taking the crank off and working on it in a vice Be careful of heating it up whilst the bearings still in place
ChUkKy Posted July 23, 2012 Posted July 23, 2012 Yep, got that sorted, still stuck. go to Gym?Then try again

ChUkKy Posted July 23, 2012 Posted July 23, 2012 Hmm, I have one of those, will give it a bash.Little heat may help but dont over do it.Ive had the problem once before and its not fun trying to get that pedal off, I eventually resorted to a hammer and some brute force with the spanner then finally it came off with a bit of swearing
RockCoach Posted July 23, 2012 Posted July 23, 2012 If none of the above does the job, then try a long tube of some sort to add leverage.
NotSoBigBen Posted July 23, 2012 Posted July 23, 2012 I have taken the crank arm off, placed it in a vice (covered in cloth) and then with that leverage I was able to loosen it .....
Andro Posted July 23, 2012 Posted July 23, 2012 I would not use a flame on it, but use a heat gun (Black and Decker) and heat allow around where pedal is screwed in.They generate quite a bit of heat and remove bearings from alu castings ect. This will work. Make sure the arm is well secure. You can burn yourself badly. Good luck.... and remember..... You can Do It.
