I'm reassembling the engine on a '46 JD A that I've had apart for three years. Trying to use the I&T manual and parts book to make sure I'm getting everything back where it belongs. The parts book shows a part #A2330R described as "Pipe, Oil, in cylinder block". This appears to be a straight pipe, maybe threaded at both ends, that goes from the fitting at the back of the block that a tube from the oil pump attaches to to the front of the block, or maybe through the head as well, where it attaches to the oil outlet washer (A2354R), on which there's a fitting that the tappet oiler attaches to. When I put the block back on the crankcase, I attached the tube from the pump to the fitting on the block, but I don't seem to have a pipe to put through the hole in the block that leads to that fitting in the back. I don't *think* I've lost any parts, but a lot can happen in three years, especially in *my* shop, if you know what I mean ;-) So, the question is, am I missing this pipe, and if so, what does it look like? The hole in the front of the block is maybe a quarter inch in diameter, which means that pipe must be pretty narrow to fit through there. Or is it possible that the pipe is still in the hole and ends flush with the front of the block? Can't tell from the diagrams in the parts book or I&T how this really fits together or what it looks like when in-place, and I sure can't remember what it looked like when I took it apart (I didn't REALLY intend to have it apart for three years). Is this pipe supposed to extend through both the block and the head, or just the block? How thick is it? How does it attach on the ends? Also not too clear on how the oil outlet washer fits into place. Can anyone enlighten me on any of this? Thanks in advance for any help.

The fitting that you attached the oil pipe to in the crankcase is on the end of the oil pipe that goes thru the block. the block is threaded at the front of the block for the oil pipe, but the pipe doesn't extend all the way to the front. The oil outlet washer goes on the center head stud with the threaded fitting pointing up, with the lead washer between the oil outlet and the nut. Summing up it sounds like the pipe in question was never taken out to start with. Post back if you have any more questions. Mike

The pipe runs through the block, but stops at the front. There is nothing that you need to fit into the face of the block. Pressurized oil then flows through a port in the cyl head to the manifold which connects to the tappet oil pipe. Head gasket keeps the oil from reaching the cylinders / water jacket. You should be able to continue your assembly w/o any additional parts.
