Hello well as the title says i have a left crank stuck on my coker. any idead how i could get it off?
obviously a crank extracter doesnt work (well the threads that holds the crank extracter on the crank were stripped) i am assuming the crank is knackered now but i would like to save the hub.
Don't overlook the low-budget method of simply riding the crank off. Once you remove the nut/bolt, cotterless cranks usually loosen up with surprisingly little riding. If you're able to idle, do a bunch of idling with that pedal down (turn the cycle around backwards if necessary). Or do a bunch of little hops, but keep switching your pedal position from 9-3 to 3-9.

Take it to your local garage and they'll often find a way, just ask them and they're likely to know. Some bike shops will just bang it off with a hammer too. thanks, Aaron
Another possibility is gentle heat. If you heat the crank, but keep the spindle cool, the crank will expand and will loosen. Best way is to hold the uni at an appropriate angle and pour hot water on it, so that it goes onto the crank, but doesn't go onto the hub. You could keep the hub cold with a cold wet cloth. Also, try a penetrating oil.
