Ford 600 serial number

[kleine39kermit]

I found on the flat part of the housing behind the starter the following numbers. 3 digit "640"
Below that number there is "13900"
The 6 means its a 600 series and the 4 means a 4 speed Trans.
What does the 0 mean?
the 13900 is the serial number? What year model is it? 1954 or later?

**0 - Hundred series, '55 - '57

1954 Serial number 1 - 10614
1955 Serial number 10615 - 77270
1956 Serial number 77271 - 116367
1957 Serial number 116368 - up

According to your reply, my tractor with the S/N 13900 it's a 1955 model
and that means that Ford built 66,655 in 1955. In 1954 only 10,614? Big difference.

No *00 series tractors were built as 1954 models. There were some built in late 1954 as they transitioned from the NAA series to the hundred series, but they were considered 1955 models. This model transition accounts for the low number built in 1954.

Your 640 is part of the 600 series. The last 0 designates the hundred series. The *01 series came next in 1958 with a few of them being built in late '57.

To confuse things further the model year (which is sometimes used for parts ordering) can vary from the production year. Per the Ford Parts List the model years for the 600 series is 55 to 57 not 54 to 57. BTW the serial number chart commonly found on the Internet and on this web site (link below) goes by production date. Also below is a model year summary for various tractor series taken from the parts list.

when I was working at a Ford dealer in Atlanta back in the early 80's, we were always told the the NAA production
stopped in the fall of 54 and then the line was changed to begin production of the hundred series, I'm sure some got build before the first of the year

The 6 at the beginning combined with the 0 at the end means that it is a 600 series tractor. If the last digit was a 1 then it would be a 601 series tractor, which was what replaced the 600 series tractor.

The middle digit specifies transmission and PTO options. The 4 in the middle position means that it has a 4 speed transmission and transmission driven (non-live) 540 rpm PTO.

My 640 has only a 3 number serial#, 739, what does that mean for year ??

That means that it was assembled in late 1954 for the 1955 model year.

This makes since as this one has a number of differences from other 55-57 I,ve seen. Most notable it has a cast housing on the out end of the exhaust that directs the exhaust up. When I took it off to replace muffler I found it was all original. It also has a dozer blade attached that appears to be original., so maybe a demo for the new series!!

Just bought a sweet 600 series as per hoods medallion. The stamped numbers on the flat area behind starter says 640 then below are 6 numbers that don't seem to coincide with what's offered above? 102187 any help would be appreciated, Thanks, Wolfowner

The 70-year-old man I bought it from (proudly in his mind) says it's a 1953 Jubilee. I didn't have the heart to tell him any different.

640 is the model, which is a model in the 600 series. It has a 4 speed transmission and transmission driven (non-live) PTO. The 600 series was made for the 1955 through 1957 model years. 102187 is the serial number. For the hundred series, that is a 1956 serial number. Every time Ford came out with a new series, they started with new serial numbers, either at 1 or1001 depending which new series it was. They stopped that practice with the 1965+ tractors when all models in all series simply got the next available serial number for the factory where it was assembled.

Thank you Sean for this information..

I'm confused. The Casting number on the block is 310905 and the stamped numbers are 41201 and 71068. Please tell me what this is.

 

[Destroked 450]

Your tractor has had a engine or transmission swap
310905 is a 134 ci engine block number that would have came in a 58-59 601 model
The transmission model code and serial numbers are for a 4000 model with 4 spd trans built in 1964
Post some photos of your tractor, side view, dash, rear axle

A picture of the grill and front of the hood will help also.

I like the color scheme . That is definitely a hundred or '01 series grill and hood, so the engine is probably original and the trans has most likely been swapped with one from a slightly later 4 cylinder 4000. They used the same 4 speed transmission from 1955 through 1964. So yours is a 641 for all intents and purposes.

Thanks for your help. It makes ordering parts a little easier. A friend gave it to me so, the price was right. Motor runs good and trans seems ok. I'll get her painted this winter.
