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???

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.
