Right Turn
Hydraulic System: Hydraulic Flow Diagrams
When a right turn is made with the engine running, the turning of the steering
wheel positions the steering control spool valve so that flow goes through the
top of the spool. Flow entering the steering control valve at the P port passes
through the rotary meter and is directed out port R. Pressure extends the
steering cylinder for a right turn. The rotary meter ensures that the fluid flow to
the cylinder is proportional to the amount of the turning on the steering wheel.
Fluid leaving the cylinder flows back through the spool valve, then out the T port
and to the hydraulic reservoir (front axle).
