(2) Discharge the air and turn the steering wheel for several times to raise the fluid temperature to
50-60 .℃
(3) Start the engine and keep it rotating at a speed of 1000±100r/min.
(4) Close the cut-off valve of the pressure gauge completely and check if the safety pressure of the
oil pump is within the standard value. Standard value: 8MPa.
(5) Replace the oil pump in case of a deflection from the standard value.
(6) Open the cut-off valve of the pressure gauge completely and check if the oil pressure is within
the standard value without load.
Standard value: 0.2-0.7MPa.
(7) Any deflection from the standard value can be considered to be caused by a poor fuel line or
steering gear. Repair it and measure the pressure again.
(8) Check if the oil pressure is within the standard value in a state of turning the steering wheel
from lock to lock. Standard value: 7.9MPa.
(9) In case of an oil pressure lower than the standard value, remove and install the steering gear;
in case of a higher one, replace the oil pump.
(10) Tighten the high pressure hose with specified tightening torque after removing the special tool.
Tightening torque: 55±5N·m.
