4.6.2 Hydraulic Plumbing
WARNING!
From this point in the installation the
booms will be inoperative until the
electronics are fully installed.
When changing the boom
hydraulic hoses, leave the booms in
the TRANSPORT POSITION.
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.
Do NOT remove the fittings
installed in the NORAC valve
block in Section 4.6.1. Any
adapting required must be done
after these components.
2. Remove the sprayer’s boom raise lines
from the cylinders and valve block.
The raise lines are located on
the rod end of the cylinder.
3. Use the 8MBP plug (F09) to cap the
sprayer’s valve block where the two
hoses were removed.
4. Use hoses H08 and H06 to connect
the raise side of the cylinders to the
NORAC valve block “B” ports.
5. Insert the two 8MB 6MOR fittings (F04)
into the spare pressure (“P”) and tank
(“T”) ports on the Nitro valve block.
6. Connect the two remaining hoses
(H04) to the pressure (“P”) and tank
(“T”) ports on the NORAC valve block
(V01). Connect the other end of hoses
H04 to the fittings on the “P” and “T”
ports (F04).
If the sprayer does not have wing
accumulators then steps 7 to 9
can be ignored.
7. Remove the 8MB 8MOR fitting from the
bottom of the wing accumulators.
8. Insert the 8FORX 6MOR adapter (F05)
into the accumulators.
9. Connect the 8MOR 6FOR adapters
(F07) to the bottom of fitting F05, with
the inline orifice (F06) between the two
fittings. The inline orifice is the disc
orifice with an o-ring groove on one
side and an o-ring (F13) on the other
side.
