Advice on sprocket replacement?

[Cormanus]

I've done it, Bob, but I can't remember exactly how. I know, though, that I didn't lose the clutch juice in the process. The slave cylinder comes off intact leaving the pipework connected and you can then get at the front sprocket OK.

By the way, if I can do it, you'll have no trouble. I can't even get the bonding on my service manual to go back together!
