Pedal stuck in crank arm

I've got a Shimano DX pedal stuck in the right side of a  Sugino Maxi-Cross  crank arm. So far, I've tried soaking it with PB Blaster for two days and soaking it in scalding hot water, hoping that the aluminum arm would expand just a hair. I tried tapping on the spindle with a small hammer for about 10 minutes. A machinist buddy suggested that the vibration from the hammer impact would eventually break the spindle loose. He was wrong. I also, held the arm firmly in a vice, (well padded so as not to damage the arm) and got a hold of the pedal spindle with a wrench and a 20" braker bar for leverage. The damn thing won't budge. Both the pedal and the crank set are in really nice condition so I don't want to break anything here. ANY SUGGESTIONS???

Efrain Gonzales , (aka bmxdawn2dusk) is piece of work. Rather than waiting for an item to show up when it was lost in the mail, he wanted out of the deal and asked for a refund, which I gave him. Then the little guy started a call out thread making false accusations when I sold the item to someone else weeks after the post office found the item and returned it to me.

Re: Pedal stuck in crank arm

i had a pedal do the same thing to me
i took the pedal apart and ground the flange where the wrench goes so i could get a BIG crescent wrench on it
then i realized i was going the wrong way and it came right out

but i tightened the hell out of it first!! lollol

best of luck

Re: Pedal stuck in crank arm

this is a common problem that happens when steel and aluminum meet. I have seen this same problem w/ spark plugs and aluminum cylinder heads. You might want to try using a propane tourch to heat the arm and that should do it. Use antiseize when you re install a pedal on aluminum arms

Re: Pedal stuck in crank arm

Thanks for the replies. I was kind of hoping to avoid direct heat because I don't want to mess up the annodizing on the crank arm which is really nice. I guess when I go to sell it all off, the buyer will get a package deal, the pedals with the crank set.
