The implement valve detent kickout pressure testing and adjusting specifications have been changed.
Before checking the detent kickout pressure, make sure the oil temperature is near 49°C (120°F). When setting individual section detent kickouts, check the detent kickout pressure by using the signal (load sense) line rather than the work port pressure.
The actual detent kickout pressure setting and tolerance is changed from 15500 340 kPa (2250 50 psi) to 15850 1030 kPa (2300 150 psi). This allows additional flexibility in adjustment of detents for implements running at higher pressures, and accounts for the variations in kickout pressures due to temperature and pressure rise rates.
