Glad you got it figured out and reported back. I know from experience that running the oil through these valves "backwards" can result in movement or action but not the desired result. This can make the situation very confusing and frustrating.
So which ports did you end up using?. I believe you had P,T, A and B.
Yes, you guys were correct that the valve had a second port for another application. Once I started running oil through the proper direction I was getting flow out of the B port. So, P was my input pressure from the tractor, A is the pressure going to the motor, B is another pressure port for another application, I'm not sure what T is for, I assume it stands for "tank", I believe a return of some sort, I put a cap in it and it seems to be functioning normally? Then the hydraulic motor is returned back to the tractor SCV. Clear as mud? Thanks for your help Ted!
