  • The N-Series Cylinder Heads
  • I’m doing some investigating on the cylinder head used on the 9N, 2N, and 8N tractors. According to all the MPC’s (Master Parts Catalogues) here are the heads used:

    March 15, 1940 – 9N-6050-B; this is the very first MPC for the Ford-Ferguson 9N. There was never a 1939 MPC. I’d like to know what the 9N-6050 (A) head was and what the changes were.

    May 15, 1941 (9N) – 9N-6050-B

    January 2, 1942 (2N) – 9N-6050-B

    June, 1943 (2N) Moto-Tug – 9N-6050-B

    July, 1943 -9N Price List –this was only all the new 2N parts for the wartime model

    January, 1946 (2N) – 9N-6050-B

    July, 1947 (8N) – 9N-6050-B

    May, 1949 (8N) – 2NC-6050-A *

    May, 1950 (8N) – 8N-6050-A

    September, 1952 (8N) – 8N-6050-A

    It is unclear what the 1949 * "2NC-6050-A" Head was. We need clarification on this. Is it possible it was the predecessor to the 8N-6050-A head? Was the 2NC and the 8N-6050-A head issued with the cast boss where they were going to put a temperature sensor? Was that the only change to the heads over the years? Was the 8N head any different otherwise and is it interchangeable with the 9N and 2N models? Finally, what was the original 9N-6050-(A) head and what was changed to classify it as the "B" version?

  • The 9N engine was used in pick up and small deliverery trucks.It was even used in small dump trucks.Ford was able to build small trucks with the 9N engine during war time restrictions The trucks needed a temperature gauge.

  • Coupe-
    Yes, the 9N engine was used in some trucks, Worthington tractors, Industrial stationary engines, Moto-Tugs, and the Ford GPW vehicle. However, on February 10, 1942, all domestic production at FORD ceased due to the US War Board restrictions. Production wasn't started up again until October, 1942,but that was only the warhorse 2N model. By April, 1943 the restrictions had been lifted thanks to Harry Ferguson and they were allowed to go back to rubber wheeled tractors but since supplies were already slim as vendors had to get back up to speed with Ford parts in the pipeline so the line sat idle many days, weeks on end. By the way, it wasn't just FORD that had to abide by the War Board restrictions. ALL US manufacturing companies were under the order as well. The only manufacturing allowed was for wartime ordnance.

  • I believe all three heads are interchangeable. I do know that they all use the same gasket. That don't mean much though. Several differences in the engine but I do not know of anything that would affect the heads.

  • The cylinder heads are interchangeable, except the oil filter is probably going to be hard to fit if you try to use a 9N, 2N, early 8N head on a late 8N side distributor engine. I believe all of the late 8N cylinder heads had two sets of holes, so they would be a universal fit. Aftermarket cylinder heads that I have seen also have both sets of holes for the oil filter canister.

  • Re: The N-Series Cylinder Heads
  • Yeah, I believe the same gasket is listed as well, Sept, 1952 MPC anyway, 8N-6051 used on 9N, 2N, and 8N and everything in between. I know I didn't list the Sherman Hi-Compression Aluminum head but since that is a rarity, one can get the specs on it elsewhere.
