1950 and 1952 utu

I have two UTU tractors. Both are good runners. The 1950 has had the transaxle replaced has a swartz front axle. It is also not the prettiest machine out there. I am in process of installing a yetter power steering. My 1952 it not a museum piece but it is a decent looking tractor. It has had a loader on it at some point. they replaced the whole hydraulic system except the pump. The reservoir is larger and both valves have been eliminated. They were replaced by a modern single spool valve that does not require the of a moline cylinder. It also has a mechanical lift on the pto which I don't think is correct for 1952. I am thinking about playing musical parts. I want to make the 1952 an originally equipped usable tractor and make the 1950 a more usable accessorized machine. Would I have any foreseeable problems swapping the Hydraulic systems between the two of them? Will I need any gaskets or seals if I want to switch the reservoirs? Also should a tractor built in 1952 have a mechanical lift PTO? the cultivator rockshaft is the same as the 1950 which has a standard PTO. Thanks.
 
I would think a hydraulic lift rockshaft would have been recommended for 1952. Probably recomended for 1950 as well.

But the mechanical lift from an earlier model U would fit and probably the tractor had no pto shaft at all before they installed it.

You're looking at both tractors and the hydraulics. So its your call what gaskets and etc. you'll need to swap from one to the other.
 

If your aftermarket hydraulics are like the ones on my Molines, then everything should just be connected by hoses. Don't know where there would be any gaskets, unless the pump has one. But as mentioned, you know what you have, we don't.

What is a mechanical lift PTO?
 
A pto with a built in gear box activated
by a pedal that activated the cultivator
rock shaft on tractors without
hydraulics.
 
Does anything on the factory resovior/valve setup have to come apart to remove and reinstall or can it be switched as a unit?
 
if you don't have to remove the manifold, and I'm guessing your factory setup still has the manifold with metal tubes going to the rear of the tractor, I think the rest of the swap will just involve removing hoses from between the pump and the reservoir. I almost forgot some of them had a steel line on the suction side of the pump but its joined at the manifold with a short piece of 1" i.d. hose.

If you do have to remove that manifold, there are flat 0-rings in there. I was never able to get the new style OEM o-rings to work. What is working is regular round o-rings jammed in there that I got from an assortment at NAPA.
