Relief Valve Setting Pressure Test

1. Disconnect the power steering hose L.H..

2. Install  the  power  steering  tee  fitting  adaptor  to  the  steering

cylinder and connect the power steering hose L.H..

3. Install the adaptor 

D

 to the power steering tee fitting adaptor and

set the cable and pressure gauge.

4. Start the engine and set the engine speed at maximum speed.

5. Fully turn the steering wheel to the left and read the pressure

when the relief valve functions.

6. Stop the engine.

7. If the pressure is not within the factory specifications, check the

pump delivery line or replace the steering controller assembly.
