Steering Valve Installation
8 GeoSteer System
Steering Valve Installation
The installation of a Steering Valve requires a trained AutoSteer installation specialist that is familiar with hydraulics. Failure
to properly connect the Steering Valve and adjust the Load Sense Pressure Relief Valve can cause costly damage to the
vehicle’s hydraulic system. For many vehicle makes and models, specific hydraulic installation kits are available to make this
process easier and safer. These kits come with the required, Steering Valve, hoses, hose adapters, and instructions on how to
properly connect the system.
The GeoSteer system does support “Custom” installations on vehicles that are not currently supported with vehicle-specific
kits. This requires that the installer be trained in the hydraulics systems of the vehicle as well as trained with the advanced
configurations of the Steering Valve.
Note: If the installer is not familiar with the following terms and hydraulic options, they SHOULD NOT attempt a custom
installation or damage to the vehicle could occur.
• Power Beyond – Does the vehicle have one and is this a viable way to connect to the Steering Valve?
• Steering Orbitrol – Where is this located, is this a viable way to connect to the Steering Valve, and what type of hydraulic
system does the Orbitrol use?
• Open Center
• Closed Center
• Pressure Compensated
• Circuit Relief Valve – How is the vehicle’s hydraulic system protected from over pressurization?
• Load Sense – Does the system use a Load Sense circuit? What type of Load Sense is installed?
• Standard
• Dynamic
• Reactive Steering – Does the vehicle have Reactive Steering?
• Steering Valve Configuration – How should the Steering Valve be configured for each of the possible installation
scenarios?
Note: Installing the Steering Valve incorrectly can cause damage to the vehicle and/or Steering Valve. Only trained hydraulic
specialists should attempt to install a Steering Valve kit on a vehicle. If any of the terms and questions listed above are not
understood, an installation, especially a “Custom” installation, should not be attempted.
Refer to the Steering Valve Installation chapter in the vehicle-specific AutoSteer Installation
Manual provided with the installation kit for the instructions for preparing the Steering Valve,
installing the Steering Valve, and connecting the hoses between the vehicle and the Steering
Valve.
After the installation is complete, refer to the Post-Installation Procedures and Information
chapter for additional information on checking for hydraulic leaks and, if necessary, setting the
Load Sense Pressure Relief Valve.
Note: If the Steering Valve has a Load Sense Pressure Relief Valve, it is important to set this properly after the complete
installation of the system or system damage or poor performance may occur.
