What I found is the roll pin that holds the 1 3/16” nut on the pusher doesn’t last. I took one tire off the bead, and the nut just falls off. I’m debating whether I should weld the nut to the pusher screw.. it is a pain, don’t know why they didn’t put a square or 2flats on the inside of the nut and outer pusher screw to help turn the screw.. instead of relying on the roll pin.
