4.6.3 Hydraulic Plumbing – All Models
WARNING!
From this point in the installation the
booms will be inoperative until the
electronics are fully installed.
You must also 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 and
Figure 4.
2. Disconnect the existing “raise” lines from
the valve block. Connect the “raise” lines to
the “B” ports leading from the NORAC
valve block.
3. Install the 6FJCN fittings (F03) onto the
disconnected ports of the valve block.
4. Disconnect the accumulators from the tee
fittings on the left and right tilt boom
cylinders. Remove the fittings attached to
the accumulators.
5. Insert the 8MB-8MJ with orifice adapters
(F08) and the 8FJX unions between the
accumulators and the tee fittings on the
cylinders (F04) (Figure 25).
6. Tee the pressure (H04) and tank (H03)
lines for the NORAC block in to the existing
lines from the existing valve block, using the
“T” fitting (F02).
Figure 25: Accumulator Fittings
7. Disconnect the tank line from the sprayer
valve block and insert a 6FJXR 6MJT tee
(F02) between the hose and the valve block.
8. Connect hose H03 from the free end of the
tee (F02) at the tank port on the sprayer
valve block to the tank port on the NORAC
valve block.

2012 and Newer
1. Disconnect the pressure line from the
sprayer valve block. Connect a 6FJXR 6MJT
tee (F02) to the valve block using the 6MJ
8MB fitting (F09). (Figure 3)
2. Connect hose H05 to the existing pressure
line using the 8MB 8MB fitting (F10).
Connect the other end of hose H04 to the
tee (F02).
3. Connect hose H04 from the free end of the
tee (F02) at the pressure port on the
sprayer valve block to the pressure port on
the NORAC valve block.
