How do you remove a crank

[splat]

Ok I know what you are going to say , use a crank puller! well I have one of those ( and have removed lots of cranks with it ) BUT! the threads on this particular crank are totally stripped , nothing for the crank puller to hold on to. so Now any sugestions ?

If the crank in question has a place to get a grip on the inner shoulder of the crankarm, try using a gear puller or a Pittman arm puller -- they both should be available to buy or rent at your local auto parts store.

if it's just one crank arm then the following might work. this works especially well with sqaure taper but should probably work with splined BB as well. tighten the opposite crank arm so i dosn't come loose and unscrew the BB splindle bolt on the stripped side. go ride some road. it should come loose within a block or two worth of riding. try doing power-strokes on the down turn off the stripped crank. stay close to home and make sure not keep pedaling once the cranks can slide off (if you keep pedaling this will mess up your bb/crank interface if you plan on using the bb again).
goodluck. :)
