[1] CHECKING
Relief Valve Operating Pressure
1. Disconnect the power steering hose L (or R) from steering
controller, and set a pressure gauge and hose.
(Reference)
• Hose and adaptor size : 9/16-18UNF, 37 0 flare
2. Start the engine and set at maximum speed.
3. Fully turn the steering wheel to the left (or right) to check the
feeling which the steering wheel lightly locks. Read the relief
valve operating pressure when the steering wheel to the above-
mentioned lock position
by operation force at approximately 9.8
N
(1 kgf, 2.2 Ibs) of outer .
• NOTE
•
After set a pressure gauge, be sure to bleed air.
• Note
that the pressure value changes by the pump action of
the power steering controller when the steering operation is
continued after the steering wheel is lightly locked and
accurate relief valve pressure cannot be measured.
