    Default Kubota L275 hydraulics

    Replaced pump - still no hydraulic for PS, lift, or Frt end loader. All fluid is returning to trans and flows out if plug is opened. Is this a relief valve problem or a priority flow valve problem - these parts are very expensive and don't want to replace both if not needed. Thanks

    Well today I removed and cleaned the priority and relief valves, changed the hydraulic fluid and still no hydraulics. pulled relief valve and got only a drip of fluid - same at power steering line and fe loader. Removed hydraulic filter and got sucking sound and little fluid in filter. There is no filter at return line. Anyone have any ideas? Thank you.

    Is your main filter in the transmision clean? Also follow the lines and make sure none are crimped off.

    Here is a pic out of my book. It is on the left side of the tractor right at the bottom of the trans case. #19

    Hydraulics quit after fluid becomes hot. Changed fluid & filter. Added shims to relief valve springs that helped somewhat. Cannot find new relief valve. kubota dealer inticates no longer available. How do I fix the relief valve? Is there another sorce for these? Is there another fix?
