I am trying to install a hydrostatic relief valve on my X720 so that I can use a front end loader. I have the fender deck removed and tried to remove the forward directional control valve on the transmission but it appears to be in two pieces. I saw a post regarding that the 2nd piece needs to be extracted but I don't know what that entails. I took some angled heavy wires and tried to pull it out but it won't budge and I'm not sure if I can just pull it out or what. My question is how do you extract the 2nd half of that valve. Do you need a special tool to get it out?? I'm stuck right now. I sure don't want to put it back together and have the dealer do it at this point. Any help is highly appreciated.
