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 with the
6FORXR-6MORT fittings (F03). The elbow fittings currently on the JD valve block must be
replaced by the 6MB-6MOR fitting (F05).
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 4MBP plugs (F09).
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 F09.
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 fittings F03 and F04 as
shown in Figure 24, Figure 25, Figure 26 and Figure 27.
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.
There are multiple versions of JD load sense blocks on sprayers. Choose the
picture that most closely resembles the sprayer valve block and tee in
accordingly.
On some installs the Load sense hose (H06) may be too long and the excess
hose must be coiled and secured where it will not interfere with other
components.
