    Float Replacement 1938 JD 'D' Marvel Schebler DLTX-16

    HI, Any recommendations of a replacement float for the DLTX-16 carburetor? I started my D yesterday and everything was going fine, and then it quit running and had gas dripping from the carb bowl. I tried pull starting it and gas was coming out of the exhaust. I pulled the plugs and they were...

    1938 John Deere D Carburetor Removal

    Quite a few years back, my 1938 D stopped running. After buying a supposedly 'hot' magneto off of ebay and not having any success getting any spark, I sent the magneto off to Mainely Magnetos and had it rebuilt. I put it on a few weeks back and was very happy to see I again had spark. Before I...

    Oil Change On John Deere 70 Diesel

    I'm going to change oil on the John Deere 70 Diesel. I know where the drain plug and filter plug is located, but there is mention of a third plug. What is this third plug and where is it located? Does it just re-fill with engine oil or is it a separate compartment that needs it's own oil added...

    More JD 70 Pony Motor Frustration

    Okay, so I replaced the switch, points, plugs and wires, and coils after burning the coils out. Fired it up about 4 or 5 days ago, and it ran like a top. I've been starting it every day to make sure everything is still good. Today I went to start it, and it started, and then died out and...

    JD 70 Diesel Tachometer Quit

    I had posted previously about burning out the coils, points and switch on the pony motor of my 1956 John Deere 70 Diesel. In replacing the switch, the dash had to come out, which means the tachometer cable was unplugged from the back of the tach. I finally got the correct coils for the plug...

    John Deere Pony Motor Plug Wires

    Okay, so my dilemma continues after a long hard winter. See my post from last fall: https://www.yesterdaystractors.com/cgi-bin/viewit.cgi?bd=jd&th=678820 I put new coils and points in, but in re-reading my post from last fall, I see where the plug wire ends and coils must match. In...

    JD 70D Pony Motor Spark

    Okay, so I did something pretty stupid, and I'm looking for help. Many years ago, the mechanic at the local JD Dealer told my dad that it would be okay to run a 12 volt battery on our John Deere 70 Diesel pony motor to give it more cranking speed and spark, as long as the switch was not on for a...

    John Deere 70 Cranking Motor Starter

    Hi, Yesterday I went to start my 70 Diesel and everything worked as it should, but while I was letting it warm up a bit, the starter suddenly kicked on again and wouldn't quit. I didn't have a wrench handy to unhook the battery cable and eventually it got hot enough that there was a small...

    John Deere 'D' Stuck Valve?

    Hi, First let me start off by saying I am by far NOT an expert on John Deere tractors, or for that matter, anything mechanical. I can fix things if I have clear instructions and everything goes according to plan. That being said, I have a 1938 John Deere 'D' that my dad re-built in the...

    John Deere 'D' Magneto

    I'm wondering if anyone has any experience with the magnetos on the John Deere D. My D is a 1938 Model with the Edison-Splitdorf Model CD Magneto. My dad re-built this tractor in the mid-1980's, but never got the paint finished. We could never start it by the flywheel, but would have to move it...

    John Deere 70 Pony Motor Transmission Gasket

    Hi, I am currently having someone replace the clutch liner and the transmission brake on the pony motor transmission on my 70 diesel. I am able to find all parts, except I need the Cranking Engine Transmission gasket, which is part # F1997R. This part is no longer made by John Deere, and I...

    John Deere 70 Production Number Question

    I'm looking for production numbers on the various John Deere 70 Models. I have a few books such as the John Deere Tractor Data book and a few others which give me the numbers for the Diesel, Gas, LP and All Fuel. It shows that there were approximately 17,000 Gas and 14,000 Diesel models...

    Rust Inside of Gas Tank

    Hi, I'm wondering if anyone can give me any tips on which product to use on the inside of the gas tank on my 1938 'D' John Deere to adhere the specs of rust to the tank so they don't plug up the carb. It got so each time I started the tractor, it ran a little worse. It would spit and pop until...
