Pedal frozen into crank arm
#1
Hi all

Any tips for separating pedal from crank arm?

If it was not for the pedal being 'plastic' I would some heat on it.

I feel tempted to cut/drill it out - the pedal being more valuable than the steel crank arm.

Thanks in anticipation.

A good spanner and a decent lump hammer - make sure you choose the correct direction of thread! Oh you may need a vice if it's currently not connected to said crank...

A bit of WD40 might come in help...

DO NOTE which side it came off of!!!! If you are sitting on the bike and the pedal is on your left then it must be turned counter clockwise to loosen it! If it is on your right side then it must be turned clockwise to loosen it. This is the most case scenario for bikes. You probably already know that and now that I look up at marc's post lol he already said this, sorry marc Smile.

Can you take a picture and post it here?

In fact you need two heavy hammers:
- crank arms horizontally
- hold one hammer under the crank arm under the pedal thread
- hit with second hammer from above
- try to loosen it with a pedal wrench, those have a long lever to provide leverage

Thanks everybody for your advice.

I'm still disconcerted by my experience in a cycle shop when the mechanic with a proper spanner (which I don't have) stripped the thread on my alloy crank arm.

But this time its steel on steel, so perhaps cutting it out may not be necessary and yes, the WD40 seeps in. Ta.

Wise after the event, I'll put copper grease on when I pop the old pedals in the replacement alloy crank arms.
