Hi all, trying to help my elderly neighbour with his case 190 hydraulic problem. Cannot seem to find a description as to what are the inputs and outputs to the top mounted control valve ?
The problem is there's pressure coming in on the right most of the three ports which comes from the pump but nothing on the left two one seems to go to the collet st the front and one to the control valve below the pump. The bottom ports on that control valve have pressure depending on which way the lever on the pump is set but there's never pressure to the ports next to the incoming from the pump I assume the control valve is faulty ?
Can I bypass it? I think the two connectors behind the seat seat are inputs and should get pressure from the connection going into the top control valve but I'm guessing of course , any help would be much appreciated !

What’s even more amazing is that all the principals of hydraulic theory can be wrapped up in such a small package. This same package applies to any hydraulic system from the largest bulldozer to the oldest and smallest tractor. This short series will take a look at the basic layout of a simple hydraul
