Hello all, someone has asked me a curly question. He is replacing his original crown wheel 333952-11-50 pinion set up with a numerically lower set up. He has a crown wheel 357810-45-11 and two pinions...
6-49 30661 or 6-49 30765. I recall having seen a crown wheel/ pinion listing but cannot find it in the Service letters or Parts listing. Is anyone able to advise which of these pinions will suit the 45-11 crown wheel Please? Peter Toet. Technical Officer, Packard Automobile Club of Australia.

Aren't crown wheels and pinions finished as a matched set?

Generally yes, but IIRC they will have individual part numbers and are a companion set and still require
setting up in the pumpkin. They really become a "matched set' when they wear in together. Then you should not separate the set. However, the person was given one unused crown wheel and two unused pinions. The problem is which pinion is the companion part number to the crown wheel. I have a number of companion sets in the Club Stock so I shall see if any numbers co incide. I know that I have seen a listing of Crown wheel/ pinion matched numbers but cannot locate it at present.
