Hi guys. I'm looking for some help with a direction I should go. I have been restoring a Case 310G dozer with six way blade. Hydraulics all worked when it was taken apart a few years ago. Now finishing it
up with new hoses, filters, and fittings etc. Same pump and controls. Appears to be low pressure, but I'm not sure. Lift cylinders work slowly when not connected to blade. When connected, will not lift, nor
pivot. Nothing. If I lift the blade with a hydraulic jack, it will hold it in place, but drop when control is moved in either direction. Have a Cessna pump but don't have a way to check pressure. Believe
it has to be either a pump or control valve issue. Think all check valves are located in the control valve assembly and not in the pump. Any suggestions would be appreciated. Thanks in advance.
