TANK PORT TO ORBITAL HOSE
Disconnect the existing line from the orbital to the tank. On the orbital, attach a tee fitting and a 9/16”
JIC fitting end of the Tank Port to Orbital hose. Re-connect the existing tank line. Attach a new Tank
Port to Orbital line to the open port on the tee fitting. On the hydraulic valve, attach a 90-degree 9/16”
JIC fitting and connect the remaining loose end of the Tank to Orbital hose to the elbow fitting.
A-PORT TO LEFT STEER HOSE
Remove the hose attached to the left steer port of the orbital. Install a 9/16” JIC tee fitting on the
orbital and re-attach the original left steer hose. On the open port of the tee fitting, attach a 90-degree
9/16” JIC elbow. Connect one end of the “A-Port to Left Steer” hose to the elbow. Attach another 90-
degree 9/16” JIC elbow to the B-Port on the Steering Control Valve. Connect the remaining loose end
of the “A-Port to Left Steer” hose to the elbow fitting. (Shown in Figure 6)
B-PORT TO RIGHT STEER HOSE
Remove the hose attached to the right steer port of the orbital. Install a 9/16” JIC tee fitting on the
orbital and re-attach the right steer hose. On the open port of the tee fitting, attach a 90-degree 9/16”
JIC elbow. Connect one end of the B-Port to Right Steer to the elbow. Attach another 90-degree 9/16”
JIC elbow to the B-Port on the Steering Control Valve. Connect the remaining loose end of the B-Port
to Right Steer hose to the elbow fitting.
NOTE: It is important to trace the hoses so that the pressure and tank hoses are not accidentally
swapped for each other. This will cause valve failure. If the Left and Right Steer hoses are swapped,
the machine will steer in opposite direction. If the machine does steer in opposite directions, the DIN
connectors on the left/right coil stack can be switched to correct the steering.
