4.6.3 Hydraulic Plumbing
WARNING!
From this point in the installation the
booms will be inoperative until the
electronics 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). Also connect H06 to the Load
Sense (“S”) port on the valve block.
3. Tee the 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. Tee the Load Sense line (H06) directly
in to the S port of the shuttle valve
manifold using fitting F03 as shown in
Figure 25, Figure 26, Figure 27 and
Figure 28.
