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. Connect the NORAC supplied hoses (H03) to the pressure and tank ports on the NORAC
valve block (V01).
3. Tee the hoses (H03) into the ports on the sprayer valve block with 6FORXR-6MORT
fittings (F03) and 6MB-6MOR fittings (F05). The elbow fittings currently in place must be
replaced by the 6MB-6MOR fitting (F05).
4. Disconnect the existing hoses from the tilt cylinders. Remove the existing 90 degree fitting
on the rod end of each cylinder as well. Install a 6FORXR-6MORT fitting (F03) onto the
ports of each tilt cylinder. Reconnect the cylinder hoses and 90 degree fittings to the newly
installed tees.
5. Connect one end of hoses H02 to the F03 fittings on the LEFT tilt cylinder. Connect the
other end of hoses H02 to the NORAC valve block “A” and “B” ports.
6. Connect one end of hoses H04 to the F03 fittings on the RIGHT tilt cylinder. Connect the
other end of hoses H04 to the NORAC valve block “A” and “B” ports.
7. The “raise” lines must be connected to the "B" ports of the NORAC valve block.
8. The “lower” lines must be connected to the "A" ports of the NORAC valve block.
9. Connect H01 to the load sense port on the valve block.
10. Route the load sense line (H01) to the shuttle valve manifold located underneath the
sprayer.
11. Tee the load sense line (H01) directly in to the “S” port of the shuttle valve manifold using
F03 and F04.
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 (H01) may be too long and the excess
hose must be coiled and secured where it will not interfere with other
components.
