Hello guys. I have a kubota U48-4 wich im going to put a tree processor on. It needs 90 liters per minute at 190 bar. Right now the excevator can put out about 50 liters at 190 bar on the aux 1 line. It puts out about 70 liters at 0 bar at that same line. According to the manual the pump can actually output 120 liters per minute. I cant find any information about how many liters it puts out at 190 bar but in certain it wont be 90 liters. My plan is to adjust the injection pump timing and turn up the fuel a bit so i get a few extra hp so that i can adjust this pump to output more liters per minute at a higher pressure. I know how to tune the engine but i have no idea how to adjust this pump. So that is what im going to ask, how do i adjust the pump so it puts out more liters per minute at a higher pressure? These pictures are of the two adjustment points.
