Hi mpope03
Was the pump a genuine kubota or non oem pump. I received a GPO120L pump from another supplier , but it is not exactly the same . It does fit but the gasket sealing area is much smaller. I am just wondering if your pump issue was similar or was the pump exactly the same as the original pump I have another post open on this and just need to be sure before fitting it.
Was this the part you ordered in the end
I have a new hydraulic for my Kubota B8200D in from White House Products

After some work it mounts on the tractor. I added some fluid to the inlet but but it appears I get no hydraulic pressure out. Does anyone have any suggestions? Next trouble shooting item is to check the filter.
I see a right hand and left hand pump rotation in this forum. Which is the correct rotation?
Comments in general on replacing the pump. Kubota has this stupid stud with nut on the top back. So it is almost impossible to remove the old pump. Take a sawzall and cutoff the stud. Give your self some length on the stud to grap with a pair of vice grips and unscrew. If replacing with a Kubota $$$ pump go buy another bold to replace the stud.
For the after market pump you will need to cut the nut welded on the bellhousing. Again a sazall works well. I replaced it with a M8 nut. The after market pump is shaped different so I needed to buy 2 shorter M8 bolds. Since it is shaped different it interfers with the fuel filter and mount. So appears if I can get this pump working may have to modify the bracket and move the fuel filter higher on the motor.
