That little rubber thing on top had popped off, but it is just glued on. Take that off. Then, remove the screw, which is a left hand thread. Replace the crank and reassemble. I didn't use any loctite here. The rubber thing on top is glued on with a contact cement and there was enough of this to keep the screw in place.
