Rusted pedals to crank

[KelRod]

Hi,

NEED HELP. I an working on a Monark girls Holiday. The crank was rusted but it free now since trying to remove the pedals. Now the crank turns but can not remove the pedals. What is the best way to remove a set of pedals when they are rusted to the crank? I have sprayed them with PB Blaster.

Heat, PB Blaster, and a hammer. Just finesse it and once it breaks free a little bit, spray more PB Blaster on the threads and work it back and forth, and in and out. It should come out. All else fails? Cut the crank and replace it all!

Remember that one side has reverse threads. I've had good luck tightening a little the working it back.

All of the above, patience & a 4 lb. hammer. Good luck w/ it.

Kroil works the best to free up rust. You can get it here. http://www.kanolabs.com/ If it has been tightened too much then heat and try a dead blow hammer.

If going to the hammer, I would try to brace the crank arm with a piece of 2 x 4 or something similar so it (crank arm) can't move.

In the case of my girlfriend's bike, patience, PB Blaster, and a hammer got the old pedals off.

Sometimes, the shaft is bent and you don't see it hardly until you take the pedals off. As was the case for a 1961 Murray Meteor Flite I used to own several years ago.

x2 on heat. You might get lucky if you soak it for about a week but the torch is your best friend with these. V/r Shawn
