1939 John Deere A Part 14 Valve Tappets and....Uh Oh

Finishing up putting the engine together by installing valve tappet assembly and adjusting them to spec. Unfortunately I stumbled upon an unexpected surprise with the fan shaft as I was installing other components.

I never would have guessed there were different size fans. But I like your solution.

Someone needs to check what the 0.020" hot clearance measures out when its cold.

If you don’t do hard core farming on a hot day you’ll be fine.
