Dunno about size, but the crank pulley is undone in the normal way, i.e. it's not a left hand thread.

Bloody tight though, you'll have to lock the crank somehow.

I have a 12v impact driver - came from Maplin for about 20 quid. It takes 1/2 sockets. It sort of spins up to speed then whacks the socket in an undo direction. Moved the pulley bolt on my auto RV8 no problems. It's officially for undoing wheel nuts, but I've found it useful for others. Think the spec is 250 ft.lb or so.
