When you say tighten it "all the way," do you mean until the spring is completely compressed? Then back off from there? When I disassembled, I counted the turns when removing the nut and went back to the same spot. But it seems super tight like it would never slip.

Thanks for the input Adam/Kuppler. I have seen a bunch of good infop posts from you. And thanks Macanan for bringing me to this forum to find help tonight.

FYI, Dennis from Clermont put me on to part number 08033. It was like $5 versus $16 for the whole setup. And it was not so hard to change.
