rrlund,IF that is a two way valve??,then he will have to plumb the return(down) side of valve back to the sump or else he will be having pressure that can't get away.IF it is a one way valve then no problem as you say.

It is plumbed for the returning oil. Look at the pictures. The oil that comes back through the hoses going to the cylinders goes back to the tractor reservoir through the return hose coming from the "out" side of the valve. He has a hose coming from the "pressure" port of his power beyond and the return line from the other side of the valve going back in to the sump. He has that part correct. That's why I told him not to mess with the hoses going in and out of the sides of the valve.

You are maybe right,but unless that valve can be changed switched inside like pete23 said,that is a double acting valve with pressure to both ports and needs(should have)a pressure (return line)on that unused port because the pump is trying to put oil someplace it can't go.The loader will go down fine like you are saying,but if that other port is still powered,he still has a problem unless that valve has a float position,then forget what I said because your idea will work fine.

I can see what you and fixerupper are saying,but let's get the loader working before we totally confuse him. The relief valve will bypass the oil. Once it's working,let him post about the squeal when he lets it down,then we can get in to putting a T in the return line and running a hose from the other top port.
