Hi, from memory you will have to dismantle the starting handle covers then drop the chain off and remove the bottom chainwheel on the crankshaft, the waterpump should just pull off the front of the camshaft once the four mounting bolts are undone, I think the camshaft drive dog either has a nut inside it or is threaded on with a machined taper its a few years since I took one apart I sold my waterpump and nose piece on ebay last year.
