Tractor has 1900 hrs. used for mowing, not configured to front loader or rear backhoe. Hydraulic arms will not lift at all, not even a quiver. Local Kubota dealer disassemled & inspected pump and declared it "worn but it should work". I removed and cleaned the screen. It was not dirty (see light through it) and the fluid looked good (amber color not milky). Increased the bypass valve shim, nothing. While the tractor was running I backed off the bolts from the high pressure side of the pump. Expecting to get a spray it eventually started oozing out. I haven't a gauge but I am suspicious of the pump. I am baffled that the arms don't even quiver. Is there something I have missed? Also any suggestions for parts contacts are appreciated.

I have had a similar thing happen. Nothing happens at the front end loader or 3pt hitch. Tractor otherwise seems fine. Suction strainer also looked clean and normal. Replaced the suction strainer and everything went back to normal. I have seen suction strainers that looked like new and still would not allow enough fluid to pass. If your pump is not hissing or making unusual noises, it may not be the strainer - just thought I'd pass along my experiences. ....
