On the 91/92/9300 series steigers, when you pull the lever back, it pulls the spool out of the valve. Would that put fluid to the port nearest the spool?

We got a 9350 that has 3 blown lines where they come through the frame to the valve, and they're spraying bad enough one can't see which ones they are. All 3 on the pull back.
My next step is to take a line off the valve to see what happens. Didn't think to turn the flow down til after the oil bounced off the tank and soaked me from the belt up.

Maybe loosen the line just enough to see what does what.

Sorry not at all familiar with those machines. When you say ..pull back.. are you talking about the lever? Could you put two male ends on a hose and jump it around the outlets to the lines you suspect to be leaking? I have no idea if this is even close to helping do what you need. Would a parts diagram help? Does this model have a twin in the CaseIH line if so and you know what it is you could look it up online. In the link put the model in the search bar at the top. In the hydraulics the ..Control Valve and Coupler.. subsections in hydraulics looks like it may be of some help, but maybe not.
Edit to clarify: Assuming I have understood what you are doing correctly what I am suggesting is to pressurize the line from the coupler forward to find which one or where they are leaking. The pressure would be from coupler fed by a lever forward position. Hope this makes sense.

He doesn't have to match it up with a CIH tractor, the Steiger parts catalogs are available on the CIH site by Steiger model number.

In my experience it is most common that the port activation would be opposite of that, but no guarantees.

With the volume and pressure the newer models have I would think if idled and just crack the valve you would be able to see the leak or put some weight on the circuit if no leak switch hose position and weight should make it leak as it sags. Otherwise you'll have to take another shower or put a shield of some kind up.

It's a case 9350.
They're pretty much the same from the
cougar 1000 through the 91- 92- and 9350.
