Remove a stuck pedal?

[B4_Ford]

I’m trying to remove an SPD pedal from a 6500 crank arm. It will not budge (yes I’m turning in the correct direction). I’ve soaked it repeatedly with PB Blaster for days to no avail. I’d like to remove it without damaging the pedal or crank arm. I don’t have a vise grip or a torch to heat it. Any suggestions?

What tool(s) have you tried, and does it give you the option of using an Allen wrench on the back side of the pedal spindle?

And humor us:

In that image, in what direction have you been trying to turn the pedal spindle?

Do you have a bike work stand? I’ve clamped crank arms only, then used appropriate wrenches + a cheater bar with good results.

Allen wrench on the backside. I have an old mtb handlebar that I slide over the allen wrench for additional leverage.

Does the axle have an 8mm hex on the inside and, if so, was the pedal installed with it? If so #2, check for radial cracks at the peak of the hex, SPDs are prone to crack there if overtorqued, or if an undersized/worn 8mm Allen is used and when trying to removed the axle end expands locking it in place.

If, of course, you've only ever used a pedal wrench disregard.

I’ve tried both a pedal wrench and an Allen wrench, turning both in the opposite direction of the “tighten” arrow.

My repair stand is folding, so I can’t get enough leverage if I did clamp it. Inspection with a flashlight shows no signs of cracking. I’ve tried a makeshift cheater bar working on the floor, but it wasn’t as good as a solid piece of pipe and a vise grip.

Anyone want to buy a 6500 crankset with good condition SPD’s?

I gave up on a situation like that recently and went to a mechanic who had a torch to heat up the crank arm...took about 5 minutes.

I don't think you'd need a torch to heat it up - how about just a candle?

Caveat: I've never used either a torch or a candle for something like this, just brute force.

This will do it.

Can you reinstall the crank on a bike and then put a big pedal wrench on the pedal and then step on it with all your weight?

Hex (Allen) socket on a long breaker bar.

Edit: I see Greg beat me to it.

Another option is to get a 1/2" drive socket with an allen wrench of the correct size from a reputable tool manufacturer, and a cheap cheater bar from Harbor Freight:

1/2" drive, 25" long, $13 (made in China, I assume)

My long time LBS owner turned me on to this technique and he sent me to his bud who owns a body shop/garage. We couldn’t get a good grip with the Allen wrench and the pedal had no spot for a pedal wrench to bite. I pulled the pedal body off the axle, he fired up the torch, waved the flame over the crank arm for a couple of minutes and with a pair of vice grips on the axle, remove the pedal. The crank was never removed from the frame as he assured me that he’s been doing this in partnership with the LBS owner for 20 years or so.

Not sure where you are, but if you are in Metro Portland, Oregon, feel free to shoot me a PM and bring it by. I have the proper vice, hex key, and the proper breaker bar (raced motorbikes for 9 years).
