    Yes the 3pt has its own relief which is set about 200psi lower than the rest of the system.

    Finally got to check the pressure relief this afternoon. I took some pictures while doing it.
    First i warmed the tractor for about 15-20 minutes. Shut it off.
    Then i removed the right rear wheel.
    Disconnected the top coupler for the FEL. Installed the pressure gauge.
    Specs call for 2205psi pressure relief. I am reading about 2100psi @ about 2400rpm.
    Shut tractor off. I then removed the cap for the pressure relief in the FEL valve. Note: There are no shims.
    I added a .2mm shim for about an 80psi increase...as per instructions.
    Reinstalled the pressure relief.
    Started tractor up and increased rpm back to 2400.
    I read about 2200psi. (Picture come out blurry)
    Removed gauge and reconnected the top hose. Installed rear tire.
    I havent had a chance to try it...I will let you know if i see any change.

    So which one of the hex cap plugs is the pressure relief valve in your picture? Is it the rightmost one (only one with no pipe coming from it?)

    I see in the pic of the pressure relief valve you've got a shim pack - is that a Kubota part?

    Here is another picture with an arrow to the cap that is the pressure relief.
    I ordered the gauge kit from bxpanded...it came with the gauge(ready to hook up) color coded shims and instructions.
    Everything work out exactly as indicated in the instructions.
    I only needed the one .2mm shim to bring mine close to 2205psi.

    Awesome - thanks for the help. I already have a gauge - but I will go check bxpanded for that kit anyway.
