identifying 134 CI vs. 172 CI engines

I think a search of the archives will dredge up most of the codes.

With a EAE code on the motor you may also have a 640 with a replaced trans.

What are your date codes from the rear end???

Is it possible your 641 threw a rod once upon a time and inherited a block from an older tractor out of a salvage yard?

After this many years, there's really no telling what has happened. The tractor I looked at to day was an 860 painted gray and blue. The hood was from 801 (no script), the fenders were '56 or '57, the proofmeter was from an SOS tractor, the grille and emblem were from '55 - '57 800, it did not have the rectangular hole where the SOS shifter would have been removed if it was an old SOS tractor. S/N was consistent with a '56 800 series. Date codes on the axles were from June and August '56. Engine code had the EAF. I finally decided it really was a '56 860 with replacement hood and the wrong proofmeter, but there's no telling really.

I forgot I have a picture of my '55 850 axle date code loaded here under parts & pieces. This code is G225 meaning July 22, 1955.

I'm ready for someone in the know to tell me what that dial and pointer really mean.

I think I have looked in that area on my axle before, but it is covered with enough paint where it is hard to read the letters and numbers. How do you like the original tool box in the original location? Is it easy to get stuff out with the lid opening the way it does? Here is a pic of my 641 with my son.
