Kubota L345DT Hydraulic pump

[Jeff Poulson]

Here is a picture of the pump. I haven't taken anymore pictures but I will this weekend. My PS is Integral. I pulled the Relief valve and inspected it, I put a washer in the relief valve to see if that changed the psi but it didn't change it at all that's why I was thinking the pump was the problem. I bought this tractor a few years ago and have slowly been working on it. The FEL wouldn't move when I first bought it but found there no seals left in any of the cylinders. I also found the outlet was plugged with black sludge. I replaced all the seals and it worked but will not lift a bucket of dirt.

Looks like two pumps to me but more photos needed to be certain + a description on which hydraulic line goes from and to.

I haven't been able to take more pictures but these pictures are diagrams of my pumps.

You definitely have two independent pumps.

One would be for the power steering and the other for the 3 pt + FEL

I am sorry but without more photos and knowing where the lines go it is not possible to comment further

Pump 2 in the pic above is dedicated to power steering. It has a separate reservoir, separate reservoir, & all. On Pump 1, the inlet is on top, discharge on bottom.

I have a very similar setup on my L355SS & am having very similar issues.
