Spool valve not working.

[jellybean]

I have a NH T5060 with 2 spools on the back, one is pumping oil ok and the other is not. Any ideas what could be the problem and how to fix it please?

Now Then..
I just love a 'My tractor is broken, what's wrong with it challenge' ..
So, 2 spools, that's 4 couplers at the back?? 2 per spool valve..
Now, the one that works, will it tip a trailer in both couplers?? And, I assume the spool lever works OK??
Now, the one that doesn't work, can you try the trailer tipping pipe in each coupler?? What happens?? Does the lever in the cab feel OK,,,,, or not??
I have no idea about blue tractors I'm afraid, however, this information will help someone who knows,, ⚙🛠

If it has electric spools the electronics on the spool will be at fault think red light flashes on spool to indicate fault

It is not electric spools. The one that doesn't work will not pump whichever of the two ports I plug it in. Lever feels ok, maybe a little bit free. The other works fine and is delivering enough pressure to work the post driver. Presumably both supplied by the same pump. I have no idea what to check.

Did it stop working suddenly?? Or get worse over time?? Are there any flow control valves on the actual spool valve??

Is it possible the cable has broken or maybe undone itself/ come out of adjustment

I've just looked on the CNH store,,,,,, but it's waaaaaay too complicated for parts. I guess you have to know the tractor..

Well I have absolutely no idea why this worked but it did. I plugged a hydraulic motor in the the 2 ports of the spool valve and it worked. it also works now on cylinders. Cheap but very random fix, maybe I should patent it.
