10.3 Hydraulic Plumbing
From this point on in the installation the booms will be inoperative until the
hydraulics are fully installed.
1. After the NORAC valve is mounted, the hydraulic hoses and fittings can be plumbed. The
plumbing for the hydraulic circuit is shown schematically in Figure 3.
2. The “raise” lines must be connected to the “B” ports of the NORAC valve block. Insert the
tee fittings (F05) to the GVM valve block on the “raise” lines.
3. Connect the hoses H03 to the open ports on F05. Connect the 90° fitting on hoses H03 to
the “B” ports of the NORAC block.
4. Connect hoses H01 and H02 to the pressure and tank ports on the NORAC valve block.
5. Route the ends of hoses H01 and H02 along the left side of the sprayer to the pressure and
tank quick couplers.
6. Connect hose H01 to the Tank quick connect coupler. Connect hose H02 to the Pressure
quick connect coupler (Figure 26).
7. Disconnect the accumulators on both wing cylinders and insert the orifice (F07) between
the tee and the accumulator.
8. Ensure there are no other orifices present in the circuit between the NORAC valve block
and the boom cylinders.
