On my 70's schwinn the crank won't come out. I popped the pin out of the pedal arm and if i remember right it is pushed in on splines? Any tips on removing it i want to sand blast the frame tomorow but i need to finish up with tearing it apart. I am not using this crank anyways but that doesn't mean that i want to cut it off with a sawzall so don't even suggest it
