Can someone explain to me where I need to set my relief valves on an oliver 1850 diesel. There are 2 on the left and 2 on the right side of the hydraulic block. Most of the time I am running a 2 way cylinder or a hydraulic motor with 2 hoses. In the fall I do put it on a 13X71ft auger with only 1 hose for lift. What do I need to change to run the 1 hose? Do i need to adjust one relief valve? Or both? Also there is a interlock valve, where does this need to be set, in or out. Thanks in advance.

You adjust the one that is the hardest to get at( the upper one in your picture). IIRC - all the way in is for a 2 way cylinder, all the way out is for a one way cylinder.

The screws that you have the arrows pointing to adjust the raise and lower speeds. To use a one way cylinder adjust the hex head bolt near the floorboard on the right side. Turn it out for one way use, but you lose the 3 point hitch.

Thanks for the response. I thought the bolt by the floorboard had something to do with it but wasn't positive. Can the valves go bad that adjust the speed? One of the hydraulics work the one way but barely do anything going the other direction and I have both screws turned all the way in. New pump on the tractor as well.
