I was looking at it today and I can't really tell if it's one piece, hub and drum together? I was going to try taking out the 8 allens, and the big nut that's under that cover, and seeing if that would let it come off. I got side tracked mounting the tires on the 3 piece rims. Took me a month to sand blast and paint so I was anxious to see the tires on the rims .Much much easier to mount those tires than to disassemble them. Thanks, I hope the pictures help.
