Power Steering Relief Valve Setting Pressure
1. Disconnect the power steering hose from pump port (5) on the
steering controller (6) and set a pressure gauge (3) (Code No.
07916-50321) between them using power steering adaptor (1)
(Code No. 07916-50331), joint (Code No. 07916-50401) and
cable (2) (Code No. 07916-50331).
2. Start the engine and fully turn the steering wheel to the left or
right and read the pressure when the relief valve operates both
idling and maximum engine speed.
3. If the measurement is not within the factory specifications, adjust
the relief pressure by the adjusting plug (4).
IMPORTANT
• (Air Bleeding)
Start the engine, then turn the steering wheel slowly in both
directions all the way alternately a few times, and stop the
engine.
(Reference)
• One full turn of the adjusting screw changes the relief setting
pressure by approx. 2.9 MPa (30 kgf/cm
