Where can I get the little shaft that goes from the rear hand lift to the front tension disc release? It don’t seem to move when you raise the hand lift and I’ve tried bending the tab on the back of the front tension disc assembly and it’s not working. Is there another adjustment I’m missing or is it wore out?

I’ve got a 111w155 with the end of the arm shaft bent and the end wheel busted, evidently someone dropped it, does anyone have or know where I can get instructions on how to replace it? I’ve got a new hand wheel, arm shaft and bearing ordered but I haven’t been able to get the old shaft out yet. Any help would be appreciated.
