        Hello Keno tractors,

         

        that was the first think that we tought is the problem, but 2 new pumps later and 3 new seals the problem is all time present.

         

        We checked every detail in hydraulic system, there is nothing wrong. The pump is using its dedicated oil but also slowly pulls engine oil into it too. Dont even understand how is easier for pump to pull engine oil trough seal and not its dedicated oil…

        The new assumption is that pump mounting in block is not machined well and the pump axle is spun in wobbly motion and destroying the pump close tolerances.

          Hello,

           

          yes, the problem is the pump is sucking oil from engine slowly. The seal and pump are not a problem since we replaced both and installed new, we also replaced seal then checked whole hydraulic system, replaced oil, filter… My pump is not pushing the hydraulic fluid to the engine, but reverse

           

          Even experienced mechanics dont Know what to do anymore.

           

          Tinbender are you speaking about some internal pipe? Because there is no pipes between hydraulic sump and gearbox, the gearbox is the sump

            Hello,

             

            me and my brother buy one each. Mine is perfect but i spent probably 250 hours on it (replaced all Chinese screws with chrome allen screws, installed racing stainless steel exhaust pipe :), led ligts front and back, 10 BAR air compressor, air suspension seat, seat heating…. and many more)

             

            My brother does not spend somuch attention on his tractor but we cant seem to solve this problem

             

            Keno tractors, can you write me solution im from Croatia, quite different time zone and English is not my language, i would have hard time to speak to your mechanic?

             

            Tinbender, please let me Know if you remember, we are really desperate to solve this problem
