Power Steering Schematics
FROM
PUMP
When the steering wheel is turned to the right (Fig. 3),
the control valve within the steering valve shifts to close
the “AUX” port. This directs oil supplied by the steering
pump to the metering section of the steering valve. As
the steering wheel is turned, system oil is metered out
port “RT” to the steering cylinder. Oil displaced by the
other end of the steering cylinder returns to the steering
valve through port “LT” and is directed out port “OUT”
back to reservoir.
STEERING VALVE
Right Turn
NOTE: On 2WD units right turn pressure is supplied
to the rod end of the steering cylinder and left turn
pressure to the barrel end as shown. On 4WD units
these hydraulic lines are reversed (right turn pres
sure to barrel end and left turn pressure to rod end).

PUMP
When the steering wheel is stationary, the control valve
within the steering valve shifts back to neutral (Fig. 4),
allowing system oil to flow through the steering valve
and out the “AUX” port back to reservoir. Oil in the rest
of the steering circuit is then trapped.
