Hi there i have just started an overhaul of the PAS pump and have fallen at the first fence.  The ROM says to remove the pulley by undoing the nut and removing the pulley.  Simple isn’t it?  However I think I have a later model pump with a knurled round nut (mine is 77 Mk 2) rather than a hex nut.  How do I get that off?  Mole grips are slipping...
