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 3.
2. Connect the NORAC supplied hoses (H02) to the pressure (“P”) and tank (“T”) ports on
the NORAC valve block (V01).
3. Tee hoses H02 (“P” and “T” lines) into the ports on the sprayer valve block using either the
6FORXR-6MORT fittings (F03) or 8FORXR-8MORT fittings (F07).
If F07 is used, the 6MOR-8FORX coupling (F06) is necessary to connect to H02
(Figure 3).
4. The existing hoses that run to the boom tilt cylinders should be disconnected from the
sprayer valve block and reconnected to the NORAC valve block.
5. The “raise” lines must be connected to the "B" ports of the NORAC valve block. The ports
on the sprayer block must then be capped with 6MBP plugs (F02).
6. The "A" ports of the NORAC block must be connected to the “lower” lines of the
cylinders. The ports on the sprayer block must then be capped with F02.
7. Connect H06 to the Load Sense (“S”) port on the valve block. Tee the Load Sense line
(H06) directly in to the “S” port of the shuttle valve manifold using the 6FORXR-6MORT
fitting (F03) or the 4FORXR-4MORT FITTING (F04) as shown in Figure 3 and Figure 28.
If F03 is used, the 4MOR-6FORX (F08) coupling is necessary to connect to H06
(Figure 3).
Most John Deere Sprayers have orifices in the "A" and "B" lines of the boom tilt
cylinders. Remove the fitting from the cylinder to remove the orifices. The
orifice is directly beneath the fitting.
