I'm not sure what tooling I'll need to get it apart yet. I'll come up with something for the rings. I used to have a heavy duty pair of snap ring pliers for working on big equipment,  if I can find them. Not sure they'll get in there though.

I wouldn't pull the hubs, but I can't get my tires off unless I do. I'd rather not try to wrestle with all that weight. 

Until things thaw some I won't be able to move anything around the barn. I may try to do something this weekend, it'll be weather dependant. Its going to be bitter the next couple of days and my shop doesn't have heat.

I'll will let you know when I start in on the project. If your available, we'll schedule a time that I'll be tearing things down. Otherwise, I'll work at it and give you a show and tell if I get mine apart before you.
