Thanks Kip and thanks for your Tech article. I would probably have overthought the process without it and even probably have broken something.
Other than putting a small bolt in the center nut on that small shaft, using it for leverage and continuing to work it, I don't know any other way of loosening it? I suppose applying some heat with a propane or MAPP gas torch MIGHT help free it up? Maybe I'll just try PB Blaster first. It's gotta work better than WD-40.
