You should test the relief valve by using a hydraulic flow bench. The relief valve should be set to 17300 ± 700 kPa (2509 ± 100 psi).

Adjust relief valve (1) if the pressure is not correct.

Loosen the locknut (2). Turn adjusting screw (3) clockwise to increase the pressure. Turn the adjustment screw counterclockwise to decrease the pressure.

When the correct pressure is reached, install the relief valve into the steering control valve. The proper installation torque is 50 ± 7 N·m (37 ± 5 lb ft).
