    remove Monocog Square Cranks?

    I'm trying to remove the stock cranks off of the bottom bracket of my monocog. I bought the Park ccp2 for square taper cranks. I unscrewed the 8mm allen bolt. screwed in the tool and then tightened down the wrench to do the pulling. How effin hard do I have to tighten it to get the crank to come off. I'm tightening it to to point where a giant 22mm end wrench and the tool can't move it. I have to be doing something wrong.. Help!

    unscrew the through bolt wrench almost all the way, and then make sure the large bolt is all the way screwed in (to where the dust cap usually sits) before tightening the through bolt.

    it takes a little oomf, but shouldn't be that hard.

    did that. as far as I can tell the through bolt is pushing directly on the dark circle inside of the square in this picture.

    OK got it!! that took way more force than I thought. I was sure something was going to snap. If this was an expensive bike with expensive cranks and an expensive bottom bracket I wouldn't have pushed it that hard. Thanks!

    Cranks are mounted with a LOT of torque, usually around 450 ft-lbs.
