Have you checked the pressure, and if not, why not.

Have you removed any hoses to check flow?

Have you checked the basics, fluid level in reservoir, filter, filter screen, etc.

Are you using the correct fluid?

What color is the fluid?

If you are losing fluid, where is it going?

Even a manual might not tell you the theory of operation.

For instance, just where does that 2000 psi of pressure come from?

I agree with the previous poster about basics. Trying the simple stuff first is always a good way to go.

HI, I don't have a pressure test device but I know the pressure is low or the 3 point would raise? The leak is going back into the torque tube from the breather since that is the way I plumbed it to go. It was going out the breather and onto the ground. I put the correct oil into it when I refurbished the tractor about 10 years ago and have since replaced it with regular Hydro oil when told to do so by a reputable tractor mechanic. The oil level is up to the overflow level when checked at the proper place. The tractor had no hydro oil filter nor screen when I got it and I assume did not have one at manufactoring in 1951? Another old Case mechanic said he figured I didn't need one if the oil is clean and if it had worked without it for 40 yrs. I guess I have checked all the simple things first as you all said but am open to more ideas.
