Relief Valve Setting Pressure
1. Disconnect the delivery hose 1 (or 2) from steering cylinder and
set a pressure gauge (3) (Code No. 07916-50321) between them
using power steering adaptor (1) (Code No. 07916-54021), joint
(Code No. 07916-50401) and cable (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 adjust plug (4).
Q
IMPORTANT

•
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 set screw changes the relief setting pressure
by approx. 2.9 MPa (30 kgf/cm
2
, 427 psi).
