(1) Tap for the system pressure.
Install one 8T-0852 Gauge with a range of 0 to 40000 kPa (0 to 5800 psi) to the hose. Install the hose to the tap for the system pressure (1) .
Start the engine. Keep the machine in NEUTRAL. Keep the parking brake engaged.
Increase the engine speed to high idle.
Turn the steering wheel in both directions until the relief valve opens. Note the indication on the gauge. The correct relief pressure setting is 17250 350 kPa (2500 50 psi).Note: There may be air in the signal network, if there is a hesitation before reaching the relief pressure. Purge the signal lines of the air.Note: The inlet check valve for the metering pump prevents steering kickback. Steering kickback requires replacing the inlet check valve.
If the relief pressure is correct, then go to Step 7. If the relief pressure is not correct, then the steering relief valve needs adjusting.
Decrease the engine speed to low idle.
