Case 570M XT power beyond

[EarthWorks88]

Hi guys,

First post but have lurked around before when researching tractors, got lots of good info from here. I would like to tie into the hydraulic system of my Case 570M XT loader landscaper to make it more useful around my property. It lacks a PTO but does have a 3pt. Looking at the schematic it shows flow from the pump to the priority valve, then to the loader valve and then through the power beyond port feeds a flow control valve which feeds the 3pt hitch. The pump puts out 28.5gpm at 3000psi to the loader valve, the 3pt hitch valve has 0-8gpm at around 2000psi fed from the flow control valve. Is it possible to tie into the EF port on the flow control valve and use the fluid before it reaches tank? Since I would be tying into the flow control valve which feeds the 3pt hitch would I only be limited to the 2000psi of its relief valve? Not sure if the relief valve on say a 3000psi valve would be limited to the 2000psi on the 3pt hitch valve when its under full load. I am trying to plumb in an Oliver 1615 backhoe, not sure on its specs as well as a hydraulic PTO motor and some lines up front for skid steer attachments. Any help would be appreciated.

Welcome. The correct way would be to go from the power beyond port on the loader to the power in of the new valve. The new valve needs power beyond to continue the flow back to the hose that is on the power beyond now. Then just use a tee fitting to tie the tank port from new valve with the tank line coming from the loader.

This will give you full pressure to the new valve and is the simplest way to safely feed another valve.

Hope that helps and good luck.
