    Default Kubota M7040SUDH Hydraulic Pump

    Hi, does anybody know how to modify a kubota M7040SUDH tractor's hydraulic system, specifically the hydraulic pump? the existing 11 gpm pump if far from adequate! the 3pt lift and loader just does not cut it. Thanks!

    Subscribed. I don't think you can do anything to increase gpm. You can increase pressure though.

    Maybe JJ will see this and chime in. He could give you all the reasons why or why not to try that. He could also give you a technical idea of the gains you could possibly make.

    These are dangerous waters you are treading in. Misguided adjustments will surely lead to failures that might be very expensive.
