must show 200-400 psi (1,379-2,785 kPa) pressure drop.
4.
With steel spacer block (1) in place between axle (2) and axle stop (3), rotate steering wheel (4) to
full right direction.
5.
Observe that pitman arm (5) rotates counterclockwise.
NOTE
Turning plungers IN decreases power-assisted turning angle;
turning plungers OUT increases power-assisted turning angle.
6.
Turn front plunger (6) of steering gear (7) counterclockwise until high-pressure hiss is heard.
Pressure gauge must show 200-400 psi (1,379-2,758 kPa) pressure drop.
