    Dan, you mentioned in this video the need to seal the manifold bolts. Since I needed to replace the head on my B I needed to buy new bolts. I also went with brass nuts.

      Yes, you have to seal the bolts/ studs. Use some sort of high temperature thread sealant. If not coolant will come through them since some of the holes pass into the coolant channel.

    The cut outs on the pistons is so if you put cold plugs that may extend into the path of the piston the piston will not hit the spark plug. Remember that in 1947 JD came out with the gas high compression cyclone engine which increased the displacement from about 175 cubic inch to 190 cubic inch engine.

      I guess I am not familiar with what you call "cold plugs". By the sounds of it they were longer? What would their benefit be?

    Is the oil tapper assembly bolt longer than the other 8?

    • @DanielFarmChannel
      @DanielFarmChannel  ปีที่แล้ว

      Yes, according to the parts manual manual it is 5/8" longer (6-1/2 inch) than the other 8 (5-7/8 inch).

    Daniel I am about to install a new head gasket on my 39 B but it is unmarked as to which side goes where. It is clad like yours but which way do the little rings around the cylinder bore go? You have yours toward the surface of the head. Is this correct? I got it from Deere.

    • @DanielFarmChannel

      Flat side always goes toward the block. In other words, the rings to the outside.

    What do the lifters look like that run on the cam. What you are calling the cam followers.

    • @DanielFarmChannel

      I realize now I never showed them. They are small tubes open on one side for the push rod to sit in. Maybe 3/4" in diameter, about 1.5 inches long. You see them in the follower assembly in part 5.

    I'm getting around to start rebuilding my dads B. I'm told I can do the rebuild without removing the body. Is this correct?

    • @DanielFarmChannel
      @DanielFarmChannel  2 ปีที่แล้ว

      I'm not exactly sure I follow. Are you just talking about the rebuilding the engine? And what do you mean by the body? The frame rails never have to come off to take the head and block out. You can even remove the head without taking the hood and everything off. Not sure about the block though. Something tells me you can take that out also through enough manipulation but it's a bear. Hopefully that answers your question, otherwise feel free to add clarity. Thanks for watching.

      Just going to rebuild the engine. The hood and all the trim looks like a pain to disassemble. I am hoping to not have to take it all apart. I'm going to watch these 3 videos today to study up.

      @@BigLeo8772 even if you took the hood and everything off the governor shaft will still be in the way. You don't want to remove that unless you have to. With that said, I'm positive the block can come out without taking all that off. You may need to remove the head studs but I'm not sure. Good luck.

      Ok cool. It sure looks possible physically. Getting excited to start this project. The engine was seized, but we got it freed up. But trying to make it run, I found coolant in the cylinder. Really hoping on a head gasket, not a crack. It was previously rebuilt.

      @@BigLeo8772 sadly it could be a lot of things but hopefully just the head gasket like you mentioned. Head gasket, intake manifold gasket, or the B's used have tubes through the block where the push rods go. They are known to cause issues also. How long has it sat? What's the rest of the tractor like?

    So doesn't hit spark plugs

    • @DanielFarmChannel
      @DanielFarmChannel  3 ปีที่แล้ว

      I'm not sure it would interfere with the spark plugs if they were put in wrong, but you are correct in that that is the purpose of those cups on the pistons and they are obviously intended to face upward. Thanks for viewing.

    Your pistons are a lot different than the ones on my b
