my 320 bl is very slow when the throttle position is at 10 and faster at 8 ??
When you mean slow do you mean engine wise or hydraulic wise, for the engine make sure when your going from 8 9 10 on throttle position that your rpms are moving with the changing of positions not by noise but by tach, many factors could be involved hours on machine, boost pressure, are you in heavy lift, pump pressure
Get the PRV calibrated, it puts out variable Power Shift pressure at speed dial 10 to use full HP, and a fixed pressure at lower speed settings to use less HP. Later Bob
Thanks ill check that out
Well i adjusted engine speed from 1634 (tach ) to 1925 but 10 acts like im building more pressure , engine works harder with no more quickness in the hyd system
620 pilot pressure 5200 main releif , calibrated the gov actuator , still almost 6 seconds in boom lift when it should be 3.5 ! But keep thinkin , thanks
