My tractor has a “divider block for the position control valve” for the loader. The loader position control valve inlet and outlet are piped into/from this divider block. The divider block is connected in line of the discharge of the hydraulic pump. My problem is that I pulled the hydraulic hoses off without marking them and do not know which house connects to the inlet and outlet of the control valve. The Divider block has one hose on the side and one on the bottom side. There is also another port for another hose on the bottom.
Any help with this would be appreciated.
Jerry

If I understand you (disclaimer), in this case it shouldn't matter which goes where. You find it doesn't work the way it was designed until you switch it back.

I have had situations like this and by trial and error put it back together with 80% success. On the "good side" left was right and right was left--it was easy to switch the lines back again.

On the "bad side", I blew a pump, okay 2. ....

Sometimes there are color-code plastic rings, especially with quick-connect installations. You can't see them when they get covered with guck. ....
