Control Valve & Pinion

  1. Connect a 100 psi (7 kg/cm2 ) pressure gauge into pump return line, start engine and allow to idle. Pressure reading should be approximately 40 psi (2.8 kg/cm2 ). Turn steering gear left and right a small amount.
    CAUTION: Excessive turning of steering gear will cause damage to pressure gauge.
  2. Pressure should increase equal amounts as wheel is turned in either direction. A slight fall in pressure occurring before rise in pressure indicates a defective control valve. Stop and restart engine. Check that steering does not kick to one side.
