Test
Position the machine on level ground and stop the engine.
Release the pressure in the hydraulic system. Refer to Testing And Adjusting, "Hydraulic System Pressure - Release".
Illustration 1 g00451300
Pump compartment (1) Pressure tap (front pump delivery pressure) (2) Pressure tap (rear pump delivery pressure) (3) Pressure tap (power shift pressure)
Attach a 60000 kPa (8700 psi) pressure gauge to pressure tap (1) .
Start the engine.
Place the machine controls at the following settings: Power Mode, engine speed dial "10" and AEC switch OFF.
Increase the hydraulic oil temperature to 55° 5°C (131° 9°F).
Open the bucket until the bucket cylinder rod is at the full retraction.
Check the main relief valve pressure setting at pressure tap (1) .Adjust

(4) Locknut (5) Adjustment screw (6) Main relief valve
Return the control lever to the NEUTRAL position. Adjust the main relief valve pressure to 34300 490 kPa (4950 72 psi).
To adjust the main relief valve pressure, loosen locknut (4) and turn adjustment screw (5) until the pressure gauge reading at pressure tap (1) is 34300 490 kPa (4950 72 psi).
Tighten locknut (4) to a torque of 29 2 N m (21 1 lb ft).Note: Turning adjustment screw (5) clockwise increases the pressure. Turning adjustment screw (5) counterclockwise decreases the pressure.Note: Always make final pressure adjustments on pressure rise.
