Can someone detail the hub installation process for me?

I received my new Selectros yesterday and the instruction sheet included is written as though there was an exploded view of the hub with the components numbered. There isn't, so I have no idea what the hell they mean: "CAUTION!!! If the screws in position B should be removed...." On and on, not worth paper they're printed on.

The last time I messed around with Selectro hubs was the mid-'80's when a Landcruiser mechanic showed me how to service/disassemble them, and I've forgotten what he said.
