4.6.3 Hydraulic Plumbing
WARNING!
From this point in the installation the
booms will be inoperative until the
electronics are fully installed.
You must ensure there are no
other orifices present in the
circuit between the NORAC
valve block and the boom
cylinders.
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). Also connect H06 to the Load
Sense (“S”) port on the valve block.
3. Route these hoses to the sprayer valve
block.
4. Tee the hoses, H02 (“P” and “T” lines),
in to the ports on the sprayer valve
block with 6FORXR-6MORT fittings
(F03) or 8FORXR-8MORT fittings
(F07).
When F07 is used, the 6MOR-
8FORX coupling (F06) is
necessary to connect to the
hoses, H02 (Figure 3).
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 plugged 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 plugged with
F02.
7. Tee the Load Sense line (H06) directly
into the sprayer pump as shown in
Figure 27 and Figure 28. To tee in,
use the “T” fitting (F03 or F04).
Most John Deere Sprayers have
orifices in the "A" and "B" lines
of the boom lift cylinders. To
remove the orifices you must
remove the fitting from the
cylinder. The orifice is directly
beneath the fitting.
When the 6FORXR-6MORT
(F03) fitting is used, the 4MOR-
6FORX (F08) coupling is
necessary to connect to the Load
Sense line, H06 (Figure 3).
