Don,
You don't have to remove the hub to remove the drum. As Greg1.5 said, there are screws in the face of the drum holding it to the hub. Remove them and back off the adjusters if the drum hangs up on the shoes while trying to remove. I have also had to put a big pry bar between the backing plate and the drum and while pulling the pry bar thump the side of the drum with a big No-Bounce hammer. They won't fall off like a car drum will, you have to work them off!
Good luck!
Mike
