Power Steering Schematics
Right Turn
With the engine running, and the steering wheel turned
to the right, the flow travels through the top of the steer-
ing control spool. Flow enters the steering control valve
at the IN port and is divided into two paths. Most of the
flow through the valve is directed out the AUX port back
to the lift manifold, and on to the hydraulic reservoir. The
remainder of the flow is sent through the rotary meter
(V1) and out the (LH) port to the rod end of the steering
cylinder. The rotary meter ensures that the oil flow to the
cylinder is proportional to the amount of steering wheel
rotation. The steering cylinder retracts, pivoting the rear
wheels to the left. This results in a turn to the operator’s
right when the vehicle is moving forward. Fluid leaving
the steering cylinder flows back through the steering
control valve, exits through the OUT port, travels to the
lift manifold, and returns to the hydraulic reservoir.

Neutral (Straight Ahead)
With the the engine running and the steering wheel in
the neutral position (rear wheels positioned straight
ahead), the spool of the steering control valve is in the
center position. Hydraulic flow enters the steering con-
trol valve at the IN port, by-passes the rotary meter (V1)
and steering cylinder, and exits through the control valve
through the AUX port. The flow continues on to the lift
manifold and returns to the hydraulic reservoir.

Left Turn
With the engine running, and the steering wheel turned
to the left, the flow travels through the bottom of the
steering control spool. Flow enters the steering control
valve at the IN port and is divided into two paths. Most
of the flow through the valve is directed out the AUX port
back to the lift manifold, and on to the hydraulic reser-
voir. The remainder of the flow is sent through the rotary
meter (V1) and out the (RH) port to the piston end of the
steering cylinder. The rotary meter ensures that the oil
flow to the cylinder is proportional to the amount of steer-
ing wheel rotation. The steering cylinder extends, pivot-
ing the rear wheels to the right. This results in a turn to
the operator’s left when the vehicle is moving forward.
Fluid leaving the steering cylinder flows back through
the steering control valve, exits through the OUT port,
travels to the lift manifold, and returns to the hydraulic
reservoir.
