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
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. Route the Load Sense Line (H06) to the
shuttle valve manifold located underneath
the sprayer.
10. Tee the Load Sense line (H06) into the S
port of the shuttle valve manifold using
fittings F03 and F04 (Figure 27).
11. Attach hose H02 to port B on the 3 rd
station of the block. Route the free end of
the hose (H02) to the John Deere main lift
tee, which is located on the right hand end
of the John Deere valve block (Figure 25).
Figure 25: Main Lift Tee Location
12. Disconnect the John Deere main lift tee and
insert the supplied 6FORXR 6MORT tee
fitting (*F03). Attach the hose (H02) to the
6FORXR 6MORT tee fitting (*F03). See
Figure 26.
You must ensure no hydraulic
components will interfere with any
sprayer parts or be pulled tight at
any time.
