Farmall Cub

Marilyn's new Cub has a casting number (inverted) on the manifold. I haven't ever noticed a number on a manifold before. The number is very nearly a year newer than the engine the manifold is mounted on. 4-14-R (April 14,1948)


The number on the engine indicates it is an early '47. (April 19, 1947)



Were the casting numbers only on replacements? Does anyone have such a (any) number on their Cub's manifold? If so, does the code closely match those on other castings?

Yes George, My 48 has one, it's 10-1 B I think the last letter is or it could be an 8 . It's upside down as you said. Never paid any attention to it before. "Jack"

Jack, that's probably an 'R' for 48. my 50 with a 54 block does not have one. i'll check the 48.

George----MY 1948 has A #9-24-R on the manifold & #10-06-R on the engine. The 1953 and the 1956 have only # on engine.
DAVE

No visible manifold casting numbers on my '61.

My 48 does not have a casting # on the manifold. the block 10/13/R.

'48 Cub with 8-5-R (manifold) and 7-8-R (engine Block).
