"The collar in any Packard V8 is niether pressed NOR floating. It is PINCHED between the cam and the gear."

You are right, float is wrong; pinched is correct, guess I need to refer to my notes more often before speaking off the cuff. Also, IIRC, the difference between the thickness of the (thicker) collar and the retainer plate is what determines camshaft endplay.

As for the collar being pressed on or not. The early ones practically fall off, but I have never been able to remove one of the later ones. I recall using putty knives, screwdrivers, etc., but never succeeded. I just figured they were either heated and dropped on, or pressed on, but what do I know.

Hey, cut me some slack, I am just a new guy :)
