One of my levers has broken whatever it is that attaches the lever to the spring and the actual latch dog that holds the bucket on. But just what the heck is it? It has a head with a hole in it, but it isn't a hex screw. Drive it out or unscrew it or what? I expect it would be easier to see with the bucket off, but I'm hesitant to take it off for fear it won't go back on right now. Thanks in advance.
