Stuck Pedals

Ok so I have a MTB that I picked up, Its in great condition but still has the original pedals from 25 years ago. I want to pop on my SPD pedals but I cannot for the life of me remove the current pedals. I know about the thread pattern etc and I have swapped pedals before so I know that the threads are 'Normal' on the drive side and opposite on the other.

I have tried overnight soak in WD40 and also tried leverage by putting a old handle bar over the end of my pedal wrench but to no avail.

I am starting to think that a blow torch may be the only solution to expand the spindle but just wondering are there any other tricks I could use ?

    Have you tried hitting the old handle bar or wrench with a rubber mallet? Give it a real good whack
    :D:lol::)cooldad :shock: :? :cry:

    I'm pretty sure there's an article somewhere on here about the things to try.

    I will have a look for that article, I tried hitting it with the rubber handle of my hammer (hard enough that I nearly broke my d**n wrist ! )

    The cranks are some fairly rare early exage 500 LX (in mint condition) so if it looks like I could damage the arms I think I will just get the LBS to get there blow torch on it.

    Boiling water. It just might work without resorting to blowtorch. Worked on some stuck wheel nuts for ame a while back.

    Bike on its side, cranks in a vice etc for more purchase / stability? If they've been in there 25 years with no grease and you want to protect the cranks, LBS might be the most risk-free option?

    HAve you tried Coca Cola or Pepsi instead of WD40 ??

    This thing will eat everything - worked for me on few badly rusted bolts...

    WD40 is censored at most things.

    get some proper penetrating fluid.

    plus gas.

    or even the Halfords shock and release.

    I tried using my hands, legs, body weight on a wrench wrapped in an old towel. When that didn't work I took a hammer to the wrench (left the towel on) and hit as hard as I could. It only took a couple of hits for both and they were free. I put those pedals on not even a month ago and I used molykote grease. Maybe I tightened them too hard (I later noticed it said 10Nm). After 25 years I am not sure if my hammer would cut it. Worth a try though as in my mind no matter how much torque you can exert a heavy blow will pack more instant punch to dislodge a stuck/corroded/fused pedal.

    A longer pedal wrench. Never found a pedal so stuck that long pedal wrench won't shift. Plus gas will help too.

    WD40 should be banned and collected up and disposed in bonfire/expolosion sort of way. I would pay to see that happen. -wheel building and other stuff.
