Vic, I tried what you said to do and removed the bypass hose and plugged the ports. The lift arms do not move when the hose is removed and the block is plugged. This block takes the place of Part no. 35300-36720 which has a channel for the pressurized fluid to pass through into the relief valve. The block I have does not have a channel inside which leads me to believe that the ports must be connected either to each other or to a piece of equipment, FEL, which is what I am trying to do. I checked the relief valve poppet and seat and they looked ok and tried to order them but they are not available for the L295DT. I checked Messicks and Kubota. Hope you or someone can get me out of this bind and get this ole girl working again. Thank you for all your help. Stepdoctor.....
