F-12 F-14 Heads

Dave S. · Mar 28, 2013

Are there different cylinder heads for the f-12 & f-14 (gasoline, distillate, kerosene) and if there is what are the #'s on them?

As far as I know the heads are all the same, the difference was in the pistons, seemed as if the gudgeon pin was further up the pistons so that the swept volume was the same but the piston did not get as close to the top of the cylinder. Even with that, the compression ratio of the gasoline tractors was only about 4.4 to 1, similar to the compression ratio on the later letter series tractors for kerosene and distillate engines.

There is a difference in heads between F14 and F12 but not on which fuel it ran. The F14 does not have a fully round combustion chamber like an F12 does.

VERY different in the combustion chambers

F-12... 3195-D
