Thanks, wassomeoneelse. That page is a wealth of information. I've gone ahead and bookmarked it.
I don't think I'll have to go to that extent. To be honest, I think I lucked out, every screw I'm taken off so far has been a breeze and the inside of the gearbox looks it pretty good shape. I would almost swear someone a few years ago went through and cleaned it up really well. The only problem I've found so far was one of the fins is bent, but still in line with the rest of them. So, if I turn the handle hard, there's a vibration. But, I think as long as I take care of it it should last me for years.
Thanks for the help,
Mark
