The Bentley manual clearly says not use the crankshaft to hold the pulley
in place. They have a special tool which locks up the pulley. I guess they
are worried about bending the crank.
They are well aware of the things people do and try and Avert
problems. I guess it works but they had good reason to not want you
cranking on the snout end if the crankshaft.
