I have a 1070 with a case 70 loader. I was wondering if there was a way to plumb a joystick or something that would free up my remotes...has anyone ever done anything like this?

Sure there is. Did it on my 970. Plumb it into the line between the PTO valve and the original remote valve. The valve you install must have its own relief valve. I used a gresen loader valve with cable controls. I mounted the controls just to the right and above the 3 point controls. Looks factory from inside the cab. The valve itself is mounted to the side of the transmission just ahead of the right brake. I do not have a loader, but I needed 4 remote valves for several of the machines I pull. Its been on there for 25 years plus.

I would also like to do this on my 1070. My understanding is this valve needs to be a power beyond valve. I would need to take the flow from after the PTO valve routing it to the "in" port on the loader valve. Then take a line from the "power beyond" of the loader valve back to the tractor's remote valve. And lastly run a line from the "out" port on the loader valve to dump back into the sump. Would this be correct? Any recomendations on where to dump into the sump? Had been thinking of doing this but haven't really looked it over yet.

I stand corrected, where there's a will there's a way. The day you don"t learn something is the day you die.

will the valve give me both loader functions or just one? I see that prince makes a loader valve joystick. Would i have to plumb it into two supply lines or do they split one supply?

Make sure you get the valve for the application you need it for. Make sure it is for the open center hydraulic system, and runs 2 two way circuits with the one preferably having the float position. Do not get the valve with the joy stick control right on the valve or you will have to plumb all those hoses up into your cab. There is a joy stick cable control unit that only has the controls in the cab with all the oil and hoses and valve mounted under the cab. Do not forget the pressure relief in the valve. Any good hydraulic shop will be able to set you up with everything you need.

ok so one last question i put a t in one of the small lines going from the pass side of tractor to the back of the tractor to the manifold with the gray cover (there is like a 1 inch line on top and two smaller lines below it)

NO do not "T" into anything or nothing will work. Your valve must be hooked up in series in the pressure line that runs from the PTO control valve to the original remote valve under the fuel tank. It should be about a 1" steel line, or hose.

Sorry Karl, the 70 series remote valves had no provision for "power beyond" applications.There was a small gear pump offered to run a orbital motor that mounted in the engine under the alternator, but not suited for anything more.

I did the same thing Dkase did only on a 1070 to run a loader. Like he said, be sure to add in a relief valve or most likely you will split the aluminum pump housing (we won't get into how I know that). I used a 2000lb relief valve with my joystick. Going this route will also allow you to have float which you otherwise won't have. If I remember right the joystick was $300, relief valve was 40 and hoses were about 150.
