Aux.
Oil flows from the priority pressure port of the gear type auxiliary pump to
the power steering valve, then through the oil cooler, filter, and back to
reservoir. Turning the steering wheel to the right (clockwise) moves the
control spool in the steering valve to meter oil to the steering cylinder for
a right turn. Turning the steering wheel to the left (counterclockwise) has
the opposite effect. Cylinder movement forces oil out the other end of the
cylinder, back to the steering valve which directs it back to reservoir.
