    Kevin, Since I'm only seeing this now, this give-and-take may be setting a record for most drawn-out thread !

    If your loader valve has a "power-beyond" port - usually marked PB on the valve, you can connect a hose from it to the back port on the block to supply the 3-pt hitch. (exhaust flow from the loader valve still goes to the trans).
    L345, L3250, L48, L5450, never enough attachments

    Blast from the past on this post! I managed to figure it out to work around the lack of a PB port in my loader valve. It isn't going to win any awards for streamlined design but it worked like a champ all summer so I'll take it! Thanks!

One hose powers an aux valve and the other is to bring pressurized oil back from the aux valve's power-beyond port to run the 3-point hitch.

    Now is where I brag about Ronnie Bowman at Tractorsmart.com - a VERY helpful guy. I happened to have one of these adapters - but a friend is also putting a loader on a L345 so I wondered if the adapter is still available from kubota. The original is discontinued but Ronnie kept digging until he found its functional equivalent - part No. 70050-00279 price $88.30. It is the key part for tapping into the internal hydraulics for these early '80s tractors - so it's worth it's weight in gold. So is Ronnie. Great job.
    IF YOU EVER DECIDE TO RETURN YOUR HYDRAULICS TO "THE WAY IT WAS" MAKE SURE YOU KEEP THAT "LITTLE BLOCK W/ 4 HOLES SO YOU TO CAN PUT IT BACK........A REPLACEMENT IS $200.00............SOUNDS CRAZY BUT I TURNED MY SHOP INSIDE AND OUT TO FIND THE ORIG. TO CAP THE SYSTEM..........

    How did you move your exhaust to avoid the loader?
