    Cast frame A no tag

    Sorry for a late reply. I hardly ever check in here anymore. Pretty much everything that's been said is correct. Cast frame is 522600-542699, pressure cooling came just a thousand digits later at 523600, the PTO shaft seal housing changed at the same time. The only other thing that I know of...

    1941 JD A cant locate correct top tank of radiator

    If you've got the top tank from a 39 A (which you do), then you've likely got the entire radiator from a 39 A. The part/casting numbers for 39 A radiators are 1939 only, and the dimensions are different than a 40 on up. The entire radiator will bolt in the frame of a 41, but all of the parts are...

    JD Research: Code ab2234

    Chris, the codes mean whatever is printed after them on the research document. Now that description you gave about the "load equalizer"/aa4073 sure is open for interpretation. My guess would be that they might mean "roll-o-matic" and that it might be heavy duty front wheels. Almost all "special...

    John Deere H Serial # Lookup

    On the aluminum and brass tags, if you lightly press them between two smooth steel blocks, the numbers will usually show up. Sometimes they are already visible, sometimes not. You are right on the steel tags though. I have never seen one where they showed up on the backside. The numbers on steel...

    John Deere H Serial # Lookup

    dan_41jdh knows a lot of detail about H's. Maybe he will see this and chime in. I can tell you that part casting numbers will narrow it down a bit but no other number except the one on the tag will give you the details you would like to have. In my experience I would say do not bother removing a...

    A Guru and others need help with early a oil pump

    The best advice I can give you on assembling the pump is to have a parts book on hand. I think the difference you may be talking about is that yours is the style that is mounted in the side of the crankcase and driven off the crankshaft, as opposed to the style from 36 up, with the pump in the...

    Need help Identifying what year my new JD A is...

    In addition to the different maincase numbers, if it is a 39 model, check to see where the serial number tag was located. If it was on the left forward (side) corner of the maincase it was prior to about 482000. If it was on the right forward (top) corner it was after 482000. Once that is...

    Need help Identifying what year my new JD A is...

    Here is a real quick and easy way to separate between a 39 and a 40 model. The maincase on a 39 is an A1140R and on a 40 model is an A2300R. Most of the stuff on a 39 is either 39 only, or like an unstyled 38 model. A2300R was used for 1940 only and the maincase for 41 up is A2644R. Check that...

    1950 A

    Kent Peterson. I'm not going to get in a pissing match with you. You better look at your parts book. The Two-Cylinder Club serial number list is correct, it just fails to mention when anything was built. I'm well versed in the difference between model, production, calendar year. Do your...

    1950 A

    The statements given previously are correct, based on all available info. There were approximately 6808, 1950 model year, two stick transmission A's built. You are correct that they were not built in 1950 calendar year, but they are 1950 models. They did not start building the single stick at...

    1950 A

    This number crunching is hurting my head too. 7753 is the number of tags between 640246 and 647999, with no tags or tractors left out. 6808 is the number of tractors built between those two numbers according to the production log. That is only a difference of 945 (tags scrapped). That is not...

    1950 A

    Back to your original question, with the clarification of it being the round tube rear axle/2 stick. The production log says 6808, between SN 640246 and 647999 (Aug 49 through Nov 49, as 1950 models). You can't subtract one serial number from the other because they scrapped individual and groups...

    1950 A

    The serial number would help to answer the question, because people frequently think a tractor is one year model, and it ends up being another. If it is truly a 50 model AW, prior to serial number 648000 and after 640246, then it still could have had the wide front added. All that aside, there...

    D sucking oil out of air cleaner

    If there is any kind of blockage of the intake system prior to the oil bath, or if the level is too high, it's going to suck oil out of the cup.
