B- date codes

Gene and others, how does the date codes run on a B Farmall? I got the wrong tag on the seat, but under the left rear axle the date code says W-WL-RA, On the right the first letter is unreadable, then W-RA > So i assume the L is for the left!! So when was it casted?

I have a farmall A. Basically the same tractor without the wide left axle.
If it has the original motor there is a small flat spot on the block above the
magneto, with the serial number engraved thereon. you may (will ) have to clear grease and dirt to see the number flat spot is about an inch by two inches>Blessings

I have changed that, it's got a 123 engine, and the seat tag says FAA, and it's a B, so back to looking for a viable casting date code.

Something is funny there cause date codes are 1*28*0 which is Jan28 1945 Number,number and letter. Zero is easy to remember as its 45 then P 46 Q 47. Other numbers"5376 DA" are part #s the DA means a change from original. As other post says engine# is on block and that should match the one one the seat last ones made in middle and on of 47 those #s didnt match. Cast codes are the date the part was made tractors were built later. The B my Dad bought for me to help on the farm has some partd date coded 7*23*Q which was my birthday and was delivered on the farm three weeks later. It also was built in Louisville because in 1947 Bs and As were built in Chicago also. Louisville tractors started with serial#200,000. Till 47 all As and Bs were built in Chicago but in 47 they were built both places.I have the B as it stayed on the farm till 2012 when my youngest bro died then his wife gave it to me. I only live about a mile from the farm so that B has stayed the same place all its life. First time it ever sat outside over nite and got rqained on was two yrs ago during a three dy tractor ride. It was ALWAYS in the shed at nite Dad even built a new garage for a place to park it so it didnt stay in the corn crib hope this answers your questions.

Yes, the format for the date code is "Number + Number + Letter" where the + is the head of the screw used to attach the date code tag to the core before the mold is filled with sand.

I've never been able to find any date codes on any A, B or BN I've looked at for some reason.

IH Farmall (casting) date codes.

The only ones i could find, are under the axle, you have to lay on your back to see them, next to the part number, but it doesn't any make sense, and the RA is very clear.

Unfortunately the RA is not the date code.

What date codes don't make sense?

These letters are on the drop housings?

usually on the tranny and engine block other places they are found are not the normall. Ive even seen them on front wheel castings but not normal. Who knows how many places all the castings were made even different marks between letters and numb ers nothing was standard as to which part had them.

The early tractors (like 1939) had very few date codes. Over time, more seemed to show up. The later ones had codes on most major castings.

Thats what i was thinking, this looks just like a date code, with the screw heads and all showing,but it doesn't make any sense. And there's no code to interpetite.

No there on the straight axles. But you know those axles must of had other uses too, because whats the purpose of that big round grip part [the serrated casting], that's on the bottom of the axles. I am sure it's not for the us, to use a jack placement.

hat is exactly why they are there. There is another one below the differential.
