8.3 Hydraulic Plumbing
From this point on in the installation the booms will be inoperative until the
hydraulics are fully installed.
1. After the NORAC valves are mounted, the hydraulic hoses and fittings can be plumbed. The
plumbing for the hydraulic circuit is shown schematically in Figure 4.
2. Install tee fittings (EVRARD01) between the pressure and tank ports on the existing valve
block and the respective lines.
3. Connect hoses EVRARD02 from the tee fittings to the pressure (P) and tank (T) ports on
the NORAC block.
4. Remove the EVRARD hoses from the tilt cylinder “raise” lines. Ensure pressure has been
bled from the system before opening circuit.
5. Install tee fittings EVRARD04 onto the tilt cylinder. Connect the wing tilt “raise” lines to
the tee fittings using fittings EVRARD03.
6. Connect hoses EVRARD02 to the tee fitting using fittings EVRARD03. Connect the other
end of EVRARD02 to the “B” ports on the NORAC valve block.
7. The “A” ports on the NORAC block are plugged. The “lower” lines of the cylinders are to
remain attached to the EVRARD sprayer valve block.
8. Fit restricted fitting (EVRARD05) between the tilt circuit and the tilt circuit accumulator.
