Here is a site with a bunch of information and 'sploded drawings.

Making the tool isn't too hard either out of a bit of 3/8" gas pipe and cut so that it has two notches to fit into the weird locking nut inside the hub. I can't seem to find link to a DIY tool right now. I should take a photo of the one I made. Cost about $4 in parts and took all of 15 minutes to make with a hack saw and file.
