NAA Serial Number

This is my first post here. Looking for some info on NAA serial numbers. I have my grandfathers NAA. He bought it used sometime in the late 50's. It was not the standard factory red,but blue. However, red paint can be seen beneath the blue paint. I haven't run it in about 7 years. It's been stored inside and I am considering restoring it. I have found what appears to be a S/N, NAA 70058 below the brake pedals. That number would put in late '53 as a Jubilee. However, it does not have the Jubilee emblem on the grill.

Any thoughts on why the differences? I have been unable to find the S/N in the standard places.

Since the brake pedals are on the right side, what you found cannot be the serial number. A lot of the casting codes for the individual parts started with NAA as well.

There are two places where the serial number was located on the NAA tractors. Both of them were on the left side. They were not raised number in the casting like the number that you originally thought was the serial number probably looks like. They are always stamped into the metal, not raised up.

On the early ones it was on the engine block on the left hand side (as you are sitting on the tractor) near the front of the engine up high, just below the head. On the later ones it was on on the lip just below the flat spot on the transmission bell housing on the left side near the starter.

If it has had the engine or transmission replaced over the years then it is possible that it has a newer engine and an older transmission and so it has no serial number. If that is the case then you need to check the date codes for all of the major components (engine, transmission, rear axle trumpets and center housing and hydraulic top cover) and then you will probably be able to figure out what year the majority of them were assembled in and that is most likely the year that the tractor was built and any with out lying date codes were most likely swapped out at some point.

Sean is correct in his assessment. My question is, is there
particular reason to want to know the exact year?

The NAA was built in the '53 and '54 model years.
Other than the nose badge and some very early changes, like the
serial number location, they're the same tractor. Parts interchange.

I had an early '53 with no serial number on the transmission that
had an engine out of a '58-62 641 in it. Same 134 CI engine, different
casting code, but it all worked well. Lots of parts get changed over
the years.

BTW, welcome to the forum!

There are two locations that the serial # might be on a Jub/NAA. Right behind the starter bump out and on the front left side of engine. If the engine or the trans was replaced it is possible to have two sets of numbers or no numbers at all.

Here you go, but as stated below, don't put a whole lot into serial numbers. As a newbie, the best investment you can make is to get a copy of the Clymer/I&T FO-19 Manual and a copy of the '39-'53 FORD MPC (Master Pas Catalog) and a copy of the OEM Ford NAA Operator's Manual. The NAA Model was introduced in September, 1952. It was the new 1953 Model and had the wheat straw nose emblem with GOLDEN JUBILEE to honor the 50 years of FoMoCo. The '54 NAA had no Jubilee lettering but was almost identical to the '53 model. In 1954 Ford introduced the 600 Model. Both the NAA and 600 had the new Red Tiger OHC 134 CID and were virtually the same tractor with only a few minor changes.

Welcome aboard. Other posts addressed the serial number question, I will comment on the incorrect color. It was common for dealerships to repaint used tractors in blue and gray once Ford changed to that color scheme. I have even seen advertising that promoted repainting in the blue/gray colors. And many people would repaint tractors with colors other than factory colors. I am sure you have seen 9n and 2n tractors painted with the 8n colors, which was quite common at one time.

Thanks JK-NY. I'm debating whether to go back with the blue. As a youngster in the 60's, I spent many an hour riding on the back while grandad plowed. The blue is etched in my mind.

Thanks gentlemen for the replies. Very helpful. I am kind of a serial number nut, and it is likely it was overhauled before my grandfather purchased it. I will look again for the serial numbers on the left side. Looking forward to more discussion.

If your Grandfather bought it in the late '50s I doubt that it had been overhauled in that short of time, unless it had many many hours on it or had been abused.

I really don't know all the details. I remember riding on it in the early 60's as a child. I wish I had asked more questions back in the day.
