Some more info on my most current 3054 fix. According to Ben at Eton Tractor, Kioti's fix for this hydraulics problem includes the different pump, a hydraulic hose kit(which is supposed to improve performance), the entire valve unit for the BH, and a new panel for the BH's operating panel (new valve unit will not bolt up to original oper. panel).
Some reasons why for the pump and valve unit replacement, at least as it's been explained to me:
1. Pump for the XS TLB has more demand on it. Even though the 3054's pump was upgraded for this option, (TLB), it requires a pump that matches this machine's demands more correctly. I haven't been given any details about pump output or design differences as of yet.
2. Greater pressure or output of the new pump has caused leak on boom control. Again, as I understand it, the new unit is more compatible with the new pump.
This fix has been a work in progress as the pump was upgraded first at Kioti's direction. Then after I got the tractor back and developed the leak, Kioti told my dealer the hose kit and valve unit work was needed. Then, after I took it back, the dealer found the valve unit wouldn't bolt up, so then Kioti will send new panel.
Through all of this the guys at the dealership, have been great, even picking up and delivering tractor for latest pump replacement (round trip @ 150 miles!). They also have kept this under warranty work even after my year was up this past March, due to it being an identified ongoing fix.
I'm hoping Kioti has come up with everything I need to resolve this.
Although I don't use my tractor in my work or commercially, still looking forward to getting my TLB to do list whittled down when it comes home!
