    Loosening Stubborn Pedal

    Sup fellahs,

    1st post ever and I'm asking for help...go figure. Anyway I'm trying to change the pedals out on my mountain bike and after getting one out of the way the other has been really stubborn. I've been using a size 15 wrench and lots of WD40 in attempts to break any rust/dirt that seeped into the grooves. Any other methods you guys might suggest.

    The left one has left hand threads. If that isn't the problem,then a longer wrench or cheater bar.

    WD40 not really the best penetrating lube in the world. Take a trip to the local auto parts store and look for PB Blaster.

    I am pretty sure I have been going at it the right way, but I'll dbl check, that would explain all the struggle. Thanx for the suggestions, i'll check the way I'm loosening and prob get a longer wrench, I've heard of PB Blaster but never used it b4, this sounds like a perfect time.
    Tnx for the help everyone.

    get a park pedal wrench. Then take an old seatpost or fork tube and put it over the end of the wrench. That ought to give you enough leverage.

    also you can try a propane torch. Aluminum expands more than steel when it gets hot so a little heat might loosen things up.

    I'll bet one good shock would break it loose. Not steady pressure but smack it (the wrench) with something.

    I'll second the PBblaster recommendation, it's good chit.

    Useful trick: setup the wrench so that you can stand on the opposite pedal while you try to pry the stuck pedal loose. More torque is useful.

    Try Liquid Wrench instead of WD40; Liquid Wrench is way superior. Never used PBBlaster so no comment on that stuff.

    Blaster rocks! A friend describes it as "just like WD-40, only it works!" It'll melt a syro-foam cup! Just try that with WD-40! Check out the can for info on the cup trick. I wish I could find it in Latvia.

    All this trouble to find I was actually tightening it. I grabbed a can of the Blaster stuff and used it and this time I actually unscrewed it and guess what, it worked. I feel so dumb.
    Thanks for your help/suggestions guys. Off to give those pedals a proper test...

    don't feel bad, most people just assume that the pedals are threaded the same way (why not, right!).

    Make sure you put a little grease on the threads of the pedals before reinstalling. It'll help with removal the next time.

    I found this in a post about eggbeaters a little further down hope it helps everyone to rember how to remove pedals.

    Eggbeater pedal removal question - hex or wrench?

    I alway say with the wrench up, Rearward to Remove , Forward to Firm... has been easy for me and the people I have told to to remember.
