Maybe the woodruff key has sheared or dropped out? If it has a woodruff
key that is.

Is this the sprocket (not pulley) on the end of the engine crankshaft? It
has a woodruff key, it also has a taper, and is secured by a left hand
threaded nut. I'd say that this was loose. The woodruff key may well be
missing.

I have a manuel which I have just found and looking further into the
problem I find I am talking aboiut the Clutch Assembly unit. The nut
for the clutch spindle holds the sprocket in place. along with washers
etc this is attached to the Cl;utch spindle and drum. The manuel shows
a Woodruff key at the other end on the unit and it is described as
'Woodruff key for clutch backplate.
Will delve further in the next day or so.
