INSTALLING THE STEERING CONTROL VALVE HOSES
See the diagram on pages 20 and 21 for hydraulic system layout.
Left Steer Hose
1. Identify the left steer port on the tractor steering orbital. Hoses may need to be traced to the hydraulic
cylinders for proper identification. Once the port has been identified, remove the hose from the tractor
steering orbital and install an appropriate tee fitting, found in the Raven adapter kit, to the steering
orbital. Once the tee fitting is installed reattach the original hose.
2. Construct a new hose to run from the A-Port on the Raven steering control valve to the open branch
on the installed tee fitting. (For more details, see the installers worksheet)
3. An additional 45 or 90 degree elbow may be installed on the Raven valve to help hose routing. These
elbows will be found in the hydraulic fitting kit.
Right Steer Hose
1. Identify the right steer port on the tractor steering orbital. Hoses may need to be traced to the hydraulic
cylinders for proper indentification. Once the port has been identified, remove the hose from the
tractor steering orbital and install an appropriate tee fitting, found in the Raven adapter kit, to the
steering orbital. Once the tee fitting is installed, reattach the original hose.
2. Construct a new hose to run from the B-Port on the Raven steering control valve to the open branch
on the installed tee fitting. (For more details, see the installers worksheet)
3. An additional 45 or 90 degree elbow may be installed on the Raven valve to help hose routing. These
elbows will be found in the hydraulic fitting kit.
Pressure Hose
1. Identify the pressure port on the tractor steering orbital. Hose may need to be traced to the hydraulic
pump for proper identification. Once the port has been identified, remove the hose from the tractor
steering orbital and install an appropriate tee fitting, found in the Raven adapter kit, to the steering
orbital. Once the tee fitting is installed, reattach the original hose.
2. Construct a new hose to run from the P-Port on the Raven steering control valve to the open branch
on the installed tee fitting. (For more details, see the installers worksheet)
3. It is extremely important that the pressure line running to the Raven steering control valve goes to the
port designated “P”. Failure to do so will result in internal o-ring failure on the valve.
4. An additional 45 or 90 degree elbow may be installed on the Raven valve to help hose routing. These
elbows will be found in the hydraulic fitting kit.
Tank Hose
1. Identify the tank port on the tractor steering orbital. Hose may need to be traced to the hydraulic
reservoir for proper identification. Once the port has been identified, remove the hose from the tractor
steering orbital and install an appropriate tee fitting, found in the Raven adapter kit, to the steering
orbital. Once the tee fitting is installed, reattach the original hose.
2. Construct a new hose to run from the T-Port on the Raven steering control valve to the open branch on
the installed tee fitting. (For more details, see the installers worksheet)
3. It is extremely important that the tank line running to the Raven steering control valve goes to the port
designated “T”. Failure to do so will result in internal o-ring failure on the valve.
4. An additional 45 or 90 degree elbow may be installed on the Raven valve to help hose routing. These
elbows will be found in the hydraulic fitting kit.
LS-PV Hose
1. Remove the load sense hose from the tractors steering orbital and connect the hose directly to the
port labeled “LS-PV” on the Raven steering control valve. To identify the load sense port on the valve,
a general rule of thumb is that the smallest hose on the orbital is the load sense hose. Once the hose
is identified, follow the hose to its origin and verify that the hose is running from the tractors priority
valve.
