8T-0856 Pressure Gauge (0 to 6,000 kPa (0 to 870 psi)) 1
Place the machine on level ground.
Stop the engine.
Release the pressure in the hydraulic system. Refer to Testing and Adjusting, "Hydraulic System Pressure - Release".

Pilot Oil Manifold Compartment (1) Pressure tap (2) Locknut (3) Adjustment screw
Connect a 6000 kPa (870 psi) pressure gauge to pressure tap (1) .Note: Pressure tap (1) may need installed on your machine.
Start the engine.
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.
Increase the hydraulic oil temperature to 55° 5°C (131° 9°F).
Check the pilot relief valve setting at pressure tap (1) .
The pilot relief valve setting should be 4100 200 kPa (595 30 psi). If the pilot relief valve setting is not within the specification, adjust the pilot relief valve.
In order to adjust the pilot relief valve, loosen locknut (2) .
Turn adjustment screw (3) until the pressure gauge reading at pressure tap (1) is 4100 200 kPa (595 30 psi).Note: Turning adjustment screw (3) clockwise increases the pressure. Turning adjustment screw (3) counterclockwise decreases the pressure.Note: Always make final pressure adjustments on pressure rise.
Tighten locknut (2) to a torque of 49 4.9 N m (36 4 lb ft).Note: Normal operation of the engine and pilot pump are necessary for the pressure adjustment. If the results of the pressure adjustments are not correct, then the engine and the pump characteristic curve needs checked.
