I have a '56 J.C. Higgins Tank bike, the only tank bike I've ever touched with my own hands. After buying it I noticed something odd... a 3 piece crank. Turns out the factory was on strike in 1956 and they just kept making bikes anyway, albeit overseas in West Germany. My spindle is worn out and the pedal slips, I have a couple spindles I can try to use, but first I need to figure out how to remove this one, I don't have a proper tool to fit it, but a screwdriver and hammer work to make it move right or left, I just don't want to go too far until I know which way is correct. Thanks.
