5. MODIFYING THE POWER BEYOND INSTALLATION
It is necessary to install a shuttle tee valve (M) in the power beyond load sense port to allow either the
installed power beyond function or the FieldPilot valve (D) to trigger the load sense to the pump. Prepare the
shuttle tee valve by installing adapter (R) into the common port on the shuttle tee valve (M) . Install two of
the adapters (P) into the other two ports of the shuttle tee value (M) .

Remove the run tee with the power beyond load sense and the tank return hose, from the adapter in the load
sense port on the tractor valve block. Connect adapter (R) previously installed on the common port of the
shuttle tee (M) on this adapter, in its place. Install the run tee that was removed to one port of the shuttle tee
valve (M) as shown. Remove the other end of the tank return hose from the elbow adapter in the tank return
port on the tractor valve block. Install a run tee (N) on the elbow adapter and install the power beyond tank
return hose to the end of the run tee.
NOTE: The “Power Beyond” tank return line has an orifice plate in it. Be sure this is still in place.
Remove the plug from the pressure port on top of the valve block and install adapter
(S) in this opening.
