    Kubota KX71 dead man's relief valve

    I have a KX 71 with no servo control and have flow and return to the valve but nothing coming out of the servo pipes to the hand controls wondered if any one can advise on what's in the relief valve and pressures for the servo systems

    I think you are right I took pressure pipe off of servo pump and run engine with no oil coming out, I have checked suction line is clear and not delaminateing
    Do you have any idea where to get a pump as I go Quoted 1180.00 by a main dealer

    A few month ago I fitted a new engine in a kubota u10, I had no reponce on the hand control but they work before, I had to over fill the hydraulic tank to raise the level up to the servo pump, I run it for a few mins then let the oil back to the level and never had an other problem, could be a something like that.
