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). Tee the hoses, H02 (“P” and “T” lines), 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).
3. Disconnect the existing hoses from the tilt cylinders. Remove the existing 90 degree fitting
on the rod end of each cylinder. 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.
4. Connect one end of hoses H01 to the F03 fittings on the LEFT tilt cylinder. Connect the
other end of hoses H01 to the NORAC valve block “A” and “B” ports.
5. Connect one end of hoses H03 to the F03 fittings on the RIGHT tilt cylinder. Connect the
other end of hoses H03 to the NORAC valve block “A” and “B” ports.
6. The “raise” lines must be connected to the "B" ports of the NORAC valve block. The
“lower” lines must be connected to the "A" ports of the NORAC valve block.
7. Connect H06 to the Load Sense (“S”) port on the NORAC valve block. Route the Load
Sense Line (H06) to the shuttle valve manifold located underneath the sprayer. Tee the
Load Sense line (H06) into the “S” port of the shuttle valve manifold using fittings F03 and
F04 (Figure 26).
