So I picked up an old sears bike with the Shimano 333 3-speed hub. While the hub seems to be shifting and rolling fine I would like to disassemble it for cleaning and relubrication since who knows how long its been. From watching this disassembling video it appears that a special tool is needed to take apart this hub but I cannot seem to find it available on ebay or on the internets. Anybody know where I can pick one up or if there is an alternate method to go about this? I would love to use this as a beater winter bike.

I actually have a Shimano Nexus 8 hub just waiting to be used also but would prefer to use it on something a little...more quality? lol
