I don't have access to a flow-meter. I have a pressure gage. Is there a way to check flow with a pressure gage and a valve to close off flow? Does any of this make any sense? Can a flow rater be created without spending thousands of dollars? Can I just run the fluid into a bucket and use a stop watch? I don't want to just start changing pumps and valves without a reason. Wish I had good shop go to but there is none around here.
 
Well you could certainly make an educated WAG with a 5g bucket graduated into 1g increments and time it for a minute.. That will give you flow under no restriction. That and a pressure test to see what it can build will certainly tell you a few things. Easily a go/no go..

A timer and bucket is darn accurate. If you provide some detail on exactly what the problem is and what exactly you are working on it might elicit more helpful advice.

Yes sir, I have 504 International tractor with remotes and power steering. It has two pumps. The 3 point hitch is on one pump and the P/S and aux. valves are on the other pump. They work together thru a diverter valve(I think). The hitch pump will be either 4.5 gpm or 7 gpm. The P/S and aux.pump will be 12 gpm or 17 gpm. Right now I have 500 psi. on the remotes. Should be 1550 to 1600. I am trying to sort out the problem rather then just start buying pumps and valves. It seems a flow rating would tell me if it's a pump and if so which pump.

Based on that description I would expect the P/S and remotes are a totally separate system from the 3pt. The P/S subsystem is likely fed by a priority flow divider and the excess flow goes to the remotes.

A flow measurement isn't going to tell you anything useful. If you have any flow whatsoever at the remotes it should be at full pressure. Pressure has to be measured with all return paths blocked to get a meaningful number.

First step is to disconnect all down stream plumbing and measure pressure output right at the power steering/remotes pump. That will immediately tell you if the pump is producing pressure. If it is not producing 1500+ PSI that is your problem. If it is producing 1500+ PSI you have a problem somewhere in the down stream system.

(quoted from post at 13:51:02 08/03/17) Thank you sir, I will try to do that.

I did a little research on the IH 504 hydraulic system and it appears there are multiple versions. Do you know for a fact which one you have? Do you have OEM control valves mounted to the side of the tractor or just a pressure OUT port for the remotes? Can you post a picture of the hydraulic connections/fixtures/valves on the side of the tractor?
 
Good morning, It all looks original. The aux. valves look like the valves in the picture in the IT IH-201. Again, it's an International 504, not Farmall 504. All the components in the book look like mine. The valves are mounted on the transfer block and the transfer block on the cover as shown in the manual. It has two valves but only one was ever plumed with hoses. I understand basic fluid power like my 8N but this has more components. I've read the manual several times it always refers to flow ratings. That's why I started ask for advice. I'm going to haul the tractor home this weekend and I will take pictures. Again, it all looks original. I know this is the wrong forum but I've been reading this YT for five years and you seem to be the top hyd. man I've read. Thanks for your help.
