I'm replacing the old cranks on my Torker CX so I can give it to my friend who is learning. The cranks WILL NOT come off! I repeat! I have tried just about everything! They are stuck on tight and I dont have the faintest clue on how to loosen them. Any help? They are cotterless.
To take off a cotterless crank arm, you need a 'cotterless crank extractor.' (http://www.unicycle.com/shopping/shopexd.asp?id=420). If you don't have one, you could probably take it to your LBS and have them remove it.
If skate4flip's advice doesn't work for you (i.e. LBS won't do it for you) and you don't want to buy a crank puller, try a torch. Heat up the crank near the axle (but don't heat the axle) and it'll expand ever so slightly... you may be able to pound the crank off with a mallet then... put a dowel through the spokes and up against the back side of the crank (as close to the axle as possible), then smack that dowel and you may get lucky!
If you know anyone who works on cars, they might have a puller (used to remove harmonic dampners from crankshafts and the such) that would work.
