Farmall 200 Identification problems

[dracosloe]

I recently purchased a Farmall 200, the serial number plate has been destroyed through time and I am having problems finding a serial or identification number to identify my tractor, can anyone help please? Thanks in advance.

There should be a number stenciled under No1 sparkplug on a flat place on the engine. It may have heavy coats of paint or grease and dirt. Here are the starting serial numbers for each year they were made. Hal

1954--501
1955--1032
1956--10904

Thank you very much for the info, it is much appreciated.

Hal: That doesn't work after 1954. The 100 and 200 each had their own sequence of serial numbers each starting at 501. The C-123 engines used in both tractors had a common sequence of engine serial numbers.

This carried on into the 130 and 230, tractor serial numbers of each started again at 501, however the C-123 engine continued from the last 100 or 200 engine. It happened again with 140 and 240, each started at 501 tractor serial number, however the engine serial number continued from last 130 or 230. Casting date codes will be as close as he will come on a 200.

dracosloe: Read my responce to Hal. Are you looking in right place for tractor serial tag. It's different from C and SC. 200 serial tag should be on left side of clutch housing. I'm not even sure the C-123 engine started at 501 with 100 or 200. I've studied this a bit, and determined a few of those engines must have gone in SA1 or late SC, in 1954.

If it is missing, your next best bet is casting date codes. Each major casting has one and they are about 3/8" high digets with day and month by number and year by letter. They also have what looks like a round head, blade type screw head cast between each of day, month and year. The letter Z is 1954, A is 1955 and B is 1956. those castings were probably cast 1 to 3 months before tractor was built.

Here lies my problem. Under cylinder #1 is 354898 R3 under cylinder #3 is 3-300-A, between cylinders 3 and 4 c-123, does this make any sense to anybody and if so can you please help? Thanks again.

Ytmag had better change their data, that's where I found it. Hal

 

[Hugh MacKay]

dracosloe: 354898 R3 is the proper block part number for a 200. i suspect what you seeing under 3# is 3-30-A which is 30th day of March 1955. C-123 is the cubic inch displacment.

 

[dracosloe]

Thank you everyone!! I found out from all your info it is a 1955 model, I really appreciate all the help.

Hal: The data folks of the past 25 years don't get it all right. Now, I agree most of them do invite corrections, CH Wendel did it, Guy Fay did it, so did YT. It's a lot of info to compile, thus I understand mistakes were inevitable. I realize Wendel or Fay aren't going to come and change my book, however online mags could change their mistakes with the click of a mouse and a bit of typing.

I've studied this relationship between tractor and engine serial numbers on SA, SC, 100, 200, 130, 230, 140 and 240. I don't have it solved yet. A spread started to develop in SA after serial number 310300. It gradually increased. An old IH parts man was able to tell me the situation with 100, 200, 130, 230, 140 and 240.

Here are the numbers on my tractors, and I know all engines are original. SA tractor 336977 engine 338597, 130 tractor 9313 engine 56651 and 140 tractor 22157 engine 102230. Looking at differential on my 130, and total production numbers of 100, 200, 130 and 230, C-123 engine number 501 must have been in a Super A1 (one). My Super A is not off by enough that this was going on between SA and SC.

I would like to get to the bottom of this, thus if anyone has one of these tractors and is positive engine is original, I'd like to have both numbers from their tractor. If I had volume, it can be solved. My gut feeling in the case of SA after serial number 310300, is combine, swather or stationary engines. I'd like SA and SC numbers, particularly 1954 models. My e mail is open, and I have the time to solve this, just need some more info.

I have a Farmall 200 with tag # 11318 and a block serial number of 22710. The block was manufactured on 9.29.A. This is fairly close to your tractor. Marv

 

[Hugh MacKay]

Marv: Your numbers basically tell the story. 100 and 200 each started at tractor serial number 501. Assuming C-123 engines used in both started at 501, and have a common sequence of numbers, and given the fact both had similar production numbers the engine serial numbers would be aproximately double tractor serial numbers.

If dracosloe were to check his engine serial number, devide by 2, he would come awfully close to his actual tractor serial number. We probably should point out those engine serial numbers are directly below No. 1 plug and are atamped on a machined flat surface, as opposed to cast in place. Digets are about 1/4" high.

Over night I received an e mail from Jim Becker. I read it and while filing, I did something to make my mail folder disappear. I'll have to wait until the computer expert that keeps me out of trouble gets up to recover our mail box.

I had hoped Jim would post his information as he had beginning and ending, tractor and engine serial numbers for each of SA, SA1, SC, 100, 200, 130, 230, 140 and 240. I can't get to it right now anyhow, however it is Jim's information, and I'm hoping he will post and take credit for what he sent to me.
