Power Shift Pressure
(No Load) Speed Dial "10"
AEC switch OFF 4000 250 kPa (580 36 psi)
Power Shift Pressure
(Full Load) Speed Dial "10"
AEC switch OFF 1150 300 kPa (167 44 psi)

(2) Value from the pressure gaugeIntroduction
The power shift pressure check insures the commanded power shift pressure matches the actual power shift pressure during a two pump stall condition.Preliminary Tests
Testing and Adjusting, "Relief Valve (Pilot) - Test and Adjust"
Testing and Adjusting, "Relief Valve (Main) - Test and Adjust"
Testing and Adjusting, "Solenoid Valve (Proportional Reducing) - Calibrate (Power Shift Pressure)"Required Tools

Position the machine on level ground and stop the engine.
Release the pressure in the hydraulic system. Refer to Testing and Adjusting, "System Pressure - Release".
Illustration 2 g03712895
Pump compartment
(1) Pressure tap (delivery pressure for drive pump)
(2) Pressure tap (delivery pressure for idler pump)
(3) Pressure tap (power shift pressure)
Connect a 6000 kPa (870 psi) pressure gauge to pressure tap (3) to monitor power shift pressure.Test Procedure
Start the engine.
Increase the hydraulic oil temperature to 55° 5°C (131° 9°F).
Place the machine controls at the following settings: engine speed dial "10" and AEC switch OFF. Refer to Testing and Adjusting, "Engine Performance - Test (Engine Speed)" for engine rpm settings.
Check the commanded power shift pressure on the monitor. Check the actual power shift pressure at pressure tap (3). Refer to Table 1 for the specification.
Move the joystick for the boom until the boom is at the full BOOM RAISE position (full extension of boom cylinders). Hold the joystick for the boom in this position.
Check the commanded power shift pressure on the monitor. Check the actual power shift pressure at pressure tap (3). Refer to Table 1 for the specification.
Return the joystick to the NEUTRAL position.
If the power shift pressure is not within specification, proceed to Testing and Adjusting, "Main Pump (Flow) - Test (Hydraulic Power)".
