All of the ones Ive seen on the LP models the hyd reservior tank is usually mounted just like the other models, (gasoline / distillate) just in a different place. The plug that is in the back on yours would be the drain, and most of the time the plug that is in the lower middle front on yours is the vent which had a tube running to the side of the crankcase for ventilation. Im not all that familiar on how they did them on the LP models, but Im sure someone else on here will know more. I dont know everything....but I know enough to be dangerous.. Smile

The filler/drain pipe looks the same that were on several of my LP,"U" s. It has been a few yrs sense I had those tractors, so.....
I cannot tell you how the vent -over flow tube is set up on an LP "U"other than it does go into the small plate on the left side of the block.
Hope this is of a little help. clint

Tony, is this a LP U? My 1950 UTS/LP has the "box" turned 90 degrees. the fill is at the top front, the vent comes out the rear high center, the LP shield and lid wouldn't fit with the box turned the way yours is, don't know if the valves themselves would clear or not. Mine came from the factory this way. All the steel pipes on yours are also different that mine.

Alan,
Your right! I found pictures of mine just before dismantel and there is a line from lower center of block (on distributor side)to the tank.
My big question is does the Hyd tank use same oil as engine??
This tractor had not run for 30 yrs when I bought it and its been 60 yrs since I drove one

Honestly, Im not sure how that would work as Im assuming unless there would be a check valve in the vent tube / line, I would think the oil would almost constantly "leak" into the engine, and even with a check valve then most of the crankcase venting would end up in the hyd tank wouldnt it? Anyone else have an idea? The engine oil is different than the Hydraulic oil. I believe the hydraulic oil was originally what they called "Type 55" which was eventually superceded by type A transmission fluid or equivilent (Dexron II & III, Im guessing). Do you have any pictures you can post before disassembly?

That is interesting....most all the ones Ive ever seen (or paid attention to) were like John mentioned with the tank turned 90 degrees with the filler hole on the top front corner. I wonder why they changed them on the later ones, maybe the later LP tanks were slightly bigger? Anyone have an idea?

When I get A chance I will help clear up the confusion. I have a set up just like your pictures. I will take some pictures. I also will scan the parts book that list the two different boxes. BUT there are no refference pictures for the UTS set up just part numbers.
As far as the vent this was disscussed on the other web site awhille back. Basicly no Hyd oil gets to the engine. It is A clean way to vent the Hyd. It doesen't draw in any outside dust or moisture. The oil in the tank is just rotating and flowing in and out. The only rise is from expansion and contraction, due to temperature. It might be possible with a single action loader or wagon hoist, if it was released quickly would cause a gush and force some fluid into the engine. A few drops of Type A or Dextron in the engine is not going to hurt anything.
Years back when Hyd Valve lifters first came out, they used to stick and clatter due to the oils of the day. We use to put Type A in the engine to clean them up from sticking, The clatter went away IT WORKED. No engine was ever damaged. Changed the oil after the treatment.

I have never tried to post pictures on this site. But we will try. The parts book page is on another computer and it is shut down now, will post it in the morning. Hope you can tell by these pictures what I am talking about.The one picture shows where the vent tube goes in the right rear of the Hyd box. The one shows were the vent pipe comes from the left side of the engine behind the engine block and in front of the LP tank. The other shows the fill pipe. This pipe is shorter than the one on yours. I think the parts book gives the length. Now looking at it one would say the fill level is higher than the vent so fluid is going to run into the engine. But the parts book says there is a stand pipe on the inside of that vent pipe connection. Since you don't know the history of yours you will have to make sure that it is in place. There is two ways you can check. One of course would be to take the side plate off and look in. The other would be to take your plug out and fill with fluid and see if it runs out the vent fitting before it gets full. If not you should be OK. You might want to shorten your fill pipe so you can't overfill.
