Drive bolt, cap, spring, dog, sprocket, sleeve...

...you know, that bit at the end of the crankshaft that drives the chain.

You should really tackle this before removing the crownwheel at the other end of the chain as you can use this and the chain to hold things in place when you're undoing the bolt. I had already removed mine but placed it back temporarily. The bolt holding the drive cap/spring/dog/sprocket/sleeve is a normal-threaded bolt. I say this because I wasn't so sure, and when you're trying to undo the thing the spring compresses and you get this uneasy feeling that you're doing something wrong.

Anyway, heres the whole lot gone except the drive sleeve:
