    I'm trying to remove a set of pedal extenders off my crosstrail but they've welded themselves to the pedals and won't budge. 3 years being parked under a cover in the flat garden methinks.

    Anyone got any ideas on how to shift them? Wd40 has made no difference.

    We need details, @nobrakes. Pictures if you can.

    Most stuck things need;

    1) Penetrating lubricant and time.
    2) Heat/cool cycles, like with a blow-lamp.
    3) Brutal mechanical intervention.
    4) Drilling and tapping out.

    Did I mention liquid gallium?

    Probably worth mentioning a longer pedal spanner too - Park do the PW4 which is 14" long.

    If the extenders aren't fitted like conventional pedals, the same principle applies, but beware of rounding fixings.

    Physics. Increase the distance the force acts through.

    I had to remove a seatpin once using mole grips with the entire bike suspended in place in a vice in my dad's garage.

    One turn of the bike, Bob's your mother's brother.

    Extend your wrench in whatever imaginative way you can.

    "Extend your wrench in whatever imaginative way you can"

    There does come a point where the bonding of items (steel and alloy) is so great the outcome isn't as simple as 'it eventually unscrewed'.

    PlusGas is the traditional traditional fluid, can't vouch for any of the advice here.

    Bicycle Works has removed a pedal for me with heat and a great deal of human effort.

    Threads survived.

    This be true, but beware doing it with cheap spanners or worn flats on the piece. The extra force can just round off the flats and you're then stuck worse than before.

    Mine was in a "plusgas bath" for a week before the routine above. Sometimes it's a combo, lubricant leverage heat.......All before drilling it out !

    Thanks for the advice all. I have large spanners including a Park pedal one but no joy as yet.

    Here's what they look like. I don't care about the pedals, they're just cheap OEM ones and the bearings aren't great but I'd like to keep the extenders as they weren't cheap.

    Right. I'd clamp the extender in a vice, heat the bejeezus out of it with a tiny precision blowlamp (you can borrow mine) and use a tommy bar on a spanner to get the pedal off.

    Or drop them off at mine and I'll do it. Fair exchange for that fork.
