How to remove stuck pedal

post #1 of 31
Thread Starter 
I recently bought a new bike and for the first time use clipless pedals. But this bike is my "show horse". I am keeping my older road bike for commuting, my "work horse". I've always used toe clips on this bike but now I'd like to convert it to clipless pedals. I ordered some, along with the biggest, most expensive pedal wrench Performance sells, and find I can't remove the old pedals. There's no way to get enough force on the pedals to remove them. I tried wd40 and I do know that the left pedal is threaded in reverse but I just can't budge the damned thing.

Has anyone experienced this and what is the solution?

Re: How to remove stuck pedal

I dont have a "pedal wrench" I just used a 5/8 open end wrench (or at least I think it was a 5/8) But I had the same problem, I tried all day to get the dang pedal off, so I got mad of course. I went and found the biggest hammer we have, put my foot on the pedal to hold it, and WHAM, it came loose. (and no I didnt hit the pedal, I hit the wrench) You might try that if you havent.

Yup, I'd agree with that. "If at first you don't succeed, use a bigger hammer!"

They work well with glass nails, left handed screwdrivers and the occasional long stand........

Use the the best fitting wrench possible . Put an extension on it if you have one for leverage ,such as a hollow pipe.
Use anti seize lubricant on it such as wd-40.
Now apply heat from a simple propane torch to the crank or the pedal. Since there are two types of metal they will expand at a different rate.
This will work I have done it many times. Apply the WD - 40, let it sit for a while ,heat and torque the *****, it will turn.
By the way make sure youe are turning the threads in the correct dirrection since one side has reverse threads.
At the moment I can't remember which but I think it is the left side.

Re: How to remove stuck pedal

I cannot agree with most of this advice! Heat and brute force on a nice new Carbon Fibre or clear painted polished hollow alloy crank arm is just not on! Consider the damage to a BB from steel hammer blows...

Put some grease on the threads before installing the pedals. If its a new bike have the LBS demonstrate that the pedals can be easily removed, its like wheel nuts on a car, they must be user friendly, for girls too.

Unless I misunderstood it is an old bike and the crank is probably not carbon.
Heat is the solution. You can put grease on it until doomsday if it is seized and it will make no difference.
Heat and a wrench will do the trick and unless you are a pyromaniac you can use caution and never tell it has had a torch near it.
Old pedals seize,it happens. Heat it up and it will spin free.

Correct, the bike in question is 13 years old and there's no carbon in it. The cranks are aluminum. My NEW bike is carbon but there's no pedal problem there.

Thanks, I thought heat might be the solution and wanted to see if anyone would recommend it. Assuming a not-too-hot torch, just a cheap torch for heating copper plumbing tubing, for example, how long would you need to heat the crank.

Last time I had this problem I simply removed the crank arm, put the pedal in a bench vise so the crank arm would spin and belted it a few times with a dead blow hammer. It came loose.

Probably about three minutes or so and adjust the torch to a fine point and only use the very tip of the flame as to direct the heat only whre you need it.
Should work well, just don't burn yourself with a hot wrench.

Seems to me that carefully applied heat would have less chance of seriously damaging (disfiguring, cracking, bending) the crank than whacking it with a hammer would. Plus I don't have a bench vise. And plus I would have to then handle crank removal as well.

Re: How to remove stuck pedal

same thing happened to me, LBS took care of it without a problem.

Re: How to remove stuck pedal

I had the same problem. Just put a big pipe over the wrench and get someone else to hold the other crank down with another big pipe. If this doesn't work get a bigger pipe.
or you could try putting the cranks in the oven.
