Hi group,
Well I have had a few months to ponder how water ended up in the #1 cyl in my D. So off came the head. It looks like the head had been leaking for some time b/c the combustion chamber is pitted real bad but that is for another post. The valves didnt have any oil on them when i pulled the cover off. when I removed the rocker arm box I noticed the little pipe that was attatched to the oil line from the governor to the head. The line from the governor to the head was full of oil. I got the pipe off of the rocker box and checked it against my parts breakdown and It does not look the same. Mine is a straight tube with 2 holes with cotter pins in them. My book shows a tube with 2 tubes coming off of it to direct oil onto the valves as well as a triangular piece in the middle of the pipe. Is mine home made? As is was in the tractor even if it was clean it does not look like oil would get to the valves. When the engine was running the gague showed high pressure but i dont know if it would jet oil out the holes onto the valves. Thanks in advance for all the help and advice.

Thanks again
Brad

My 1938 "D" (unstyled) has a straight length of 1/8" iron pipe with two holes drilled thru it which line up directly over the intake valve stems. Cotter pins were in the holes. I have no idea if this is original for my tractor. I drilled two more holes to line up with the exhaust valve stems to lighty oil them. On my 1938 "D", the oil supply from the governor case is gravity feed, there is no connection to the pressure system. Excess oil is collected in the gov case and it flows thru the long external tube to this oil'ing pipe. IF the styled "D" sends pressurized oil to this pipe, 10-15 psi would send a good spray of oil out past the cottar pins unless the pipe is badly clogged.

Jon, That was probably a good idea to drill some holes in your pipe over the exhaust valve stems also. I've seen some that already had holes there also. Problem with that pipe is they would come loose and spin to where oil just flowed down side of case so sometimes the pipe needs rotated some and new soft lead or copper washers under the end plug and elbow so the tube doesn't turn or leak. Later on they changed that pipe and put some extensions of about 1-1/4" x 1/8" tubing brazed on the pipe over the exhaust valves and they were bent upwards towards top of case to clear the valve springs. Cotter keys were still put in the holes over the intake valves of the oiler pipe. A flat metal piece was brazed to the pipe in middle so if pipe came loose the extensions wouldn't hit the valve springs. None of the Ds sent pressurized oil to the rocker cover and it was just shot out of nozzle at governor case and the governor gear slug oil to the elbow and it flowed down the tubing to the rocker case.

Brad, On the 31 D and up the oiler pipe should have the 2 extension tubes running off of it. Some early ones may not have had the extensions or could have changed somtime with a earlier one or just broke and fell off. The earlier Ds only had a straight tube with holes and some cotter keys in the tube. One common problem we found a lot on those tubes was the connection leaked or was loose at the cast elbow and many times the tubes were plugged up.

Thanks for the response. I guess that I will try to find an oiler with the extensio tubes coming off the main one. It is a 39 so by your post it has the wrong one. This one only has 2 holes and these holes have cotter pins in them

Thanks again
Brad

If I have oiler pipes maybe I can get some pics of them later for you or let you know on used ones. Only things different from a early D rocker cover and rocker arms were the oiler pipes and cast tappet cover. Otherwise the rocker cover was the same. They used different heads, valves, guides and push rods also.

Yea, That would be great to have some pics. If you can send them to my home email like you have done before. If you have a used one that will work for my tractor I will get it from you. Thanks again

Sorry couldn't get pics to work this evening. You might just drill more holes in it over exhaust valves and/or braze some extension tubes over the exhaust valves also. Take the tube out and make sure it doesn't already have holes there and has just turned.

I checked the pipe again and there are no other holes other than the 2 with the cotter pins in them.

Thanks again
Brad
