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???

Think twice before you send Andy Ziegler, (a.k.a. sports4u) of Wisconsin any money. His descriptions do not match the actual items and you get the old "stonewall" routine when you call him out on it.

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.
