what is the difference between an NAA and a jubilee?
Just a badge?

what does the diamond mean in the serial #
i finally found the serial # although it isnt much good!
cvphoto96154.jpg

best i can get is 08 and diamond symbol?
is this of any value for ordering parts...im sure it isnt important as it is clearly an NAA it does not have the jubilee badge!
i have been usingthis tractor around the farm ,the engine still purrrs like a kitten!
it is however leaking oil now from the bell housing (transmission front seal?)
the engine oil level never changes.
i guess i will be breaking the tractor apart to fix this leak! while im in there i may as well do a clutch job!
also while i have the transmission out i will be replacing all the shifting mechanism as the shifter is sloppy from age.(like me)
also will be doing some pto repairs and rear seal leaks a bit!
i am planning to do a photo journal of this rebuid and post it as igo maybe it will be benificial to some other enthusiasts!
 

A Jubilee is an NAA. An NAA is not necessarily a Jubilee. The NAA was built in 1953 and 1954.

Since 1953 was the 50th year or golden anniversary of Ford Motor Company and that in the Old Testament the 50th year was to be a year of Jubilee; the 1953 model was also given the special designation, Golden Jubilee.
 
Yes, Larry nailed it. In SEP 1952 FORD TRACTOR released the new NAA Model to replace the 8N Model that had been in use since JUL 1947. Work on the new model design actually began in 1951. Most 1952 8N's would have been really built in late '51 as the Highland Park factory began tooling up for the new NAA line by April, 1952. The NAA would be considered a new 1953 Model, and named the 'Golden Jubilee 1903-1953'. The names referred both to 50 years -Golden, and Jubilee was a Biblical term meaning 50 years. FoMoCo was incorporated in 1903. Some of the new features included the new 'Red Tiger' 134 cu/in OHV Engine; new hydraulics using a vane pump; new steering; flip open hood; tool box on LH running board; dash gauge console w/temp gauge; a 4-inch longer wheelbase; and a 4 higher profile. CEO Henry Ford II wanted to honor his grandfather and the company he founded and so named the 1953 NAA The Golden Jubilee and displayed a nose cone emblem with a wheat straw logo and the name Golden Jubilee in a circular outer back. It's odd that Henry the Deuce only honored the tractor as no car or truck models shared his Jubilee sentiment. Only the 1953 NAA would be designated 'The Jubilee'. When the 1954 NAA models were introduced, the wheat straw emblem no longer spelled out GOLDEN JUBILEE, only stars. FWIW & FYI: The NAA designation was simply the FORD nomenclature for defining models. 'N' was chosen in 1939 for the Tractors for no particular reason other than it was the next letter in the alphabet. The 1954 NAA was really labeled the 'NBA' but virtually the same as the 1953 model except by late '53 Ford replaced the vane pump with the a new hydraulic clutch system and a live PTO option. The NAA also has a new reduced gear ratio. FORD had meant to keep ID'g the new model numbers with letter prefix designations, like, B,C,D etc. as improvements were made but in late 1954 the new Hundred Series models were introduced instead. They would be the 500, 600, and 700 models then in 1955 the 800 and 900 Model. Also on the drawing board in 1951 were tricycle tractors. When DEARBORN MOTORS incorporated on JAN 1, 1947 with the new 8N, Henry II brought in a team of experts college-schooled in statistical process control and planning who had worked at the US War Board in WWII. FORD Tractor would now be under the scrutiny of bean counters unlike before. This team would be called 'The Whiz Kids' and one of the members was Robert McNamara, who would go on in 1961 to be John F. Kennedy's Secretary of Defense. The Whiz Kids were bent on developing a tricycle tractor saying that to be competitive with other manufactures, they needed a tricycle model in the lineup. The late Harold Brock, chief tractor engineer since 1939 disagreed and this would be one the reasons he would quit Ford in 1957. The year 1953 also saw the end of the Dearborn Motors era, now being absorbed into the FoMoCo umbrella and called the Ford Tractor and Implement Division. Parts and designs remained all the same with the only changes now being the Implement ID tag had FORD instead of Dearborn. Engine blocks were serialized AFTER the unit was machined, assembled, and tested in the QC Inspection/Lab under special breakin/test machines. Contrary to what many believe, the s/n only ID's the engine block though a s/n was also meant to ID the module year built, but many engines got swapped out that you can no longer rely on a s/n as the only definitive proof of model year. This was the system FORD used in all vehicles, not just tractors. The (<>) Diamond symbol replaced the prior STAR(*)symbol in serial number prefix and suffixes in 1950 when they switched over to cast iron cylinder sleeves from the earlier steel sleeves. It is a moot point nowadays because they no longer make steel sleeves and cast iron are the only ones made now. So, if you are trying to ID your model, a serial number will get you bragging rights to the engine block but not necessarily to the entire unit. Get your MPC and use as a guide. SEE LINK

In addition to all of that, they also made a model in the same years as the NAA that was called the NAB. It was basically identical to the NAA with the exception of the engine being designed to run completely on kerosene instead of gasoline. And the 1953 model NAB tractors also had the Golden Jubilee emblem, so not all Jubilees were NAA's, some of them were NAB's.
 
Thats one good overview of those important transitional period tractors.

While it is certainly true that the Car and truck models didnt get a special designation, anybody who sat behind the wheel in a 1953 Ford car or truck and noticed the horn button knew about that 50 year anniversary!

what does the diamond mean in the serial #?
Cast Iron Cylinder Sleeves

i guess i will be breaking the tractor apart to fix this leak! while im in there i may as well do a clutch job!
sually its the other way around. When splitting for a clutch, finally repalce that leaking trans seal!

also while i have the transmission out i will be ......
ransmission doesn't come "out" when doing a clutch and or seal.

Unless of course you just wanna do this for fun!!
 
thanks for your feedback

And to everybody that gave some info and links

yes well the clutch is not slipping or making vibrations or noise ... but if i have it apart for the seal I may as well do the clutch! Also i need to replace various shifter components as they are worn from age! likely all accessible from the top access cover.
the pto thing is all about the mower will just drop out the PTO just pop out of gear! not sure what that is about but i will be looking into that!
do you know if there are some videos out there that show the clutch/ seal replacements or the PTO set up.
i have a manual but more info and videos are handy!
