10.3 Hydraulic Plumbing – All Models
From this point on in the installation the booms will be inoperative until the
hydraulics are fully installed.
1. After the NORAC valve is 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 tilt raise lines from the wing cylinders and insert the 6FJXR 6MJT tees (F02)
between the hoses and the existing fitting.
3. Connect two hydraulic hoses (H03) from the free ends of the tees (F02) to the “B” ports
on the NORAC valve block. Secure any extra hose so that it will not impede operation.
4. Remove the existing coupling from between the accumulator and tee fittings on both
cylinders. Reconnect the accumulators using the 8JFX union (F04) and the 8MB-8MJ orifice
(F08).
5. There must be no other orifices in the hydraulic circuit between the NORAC valve block
and the tilt cylinders.
6. Disconnect the tank line from the sprayer valve block and insert a 6FJXR 6MJT tee (F02)
between the hose and the valve block.
7. Connect hose H02 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.
10.4 Pressure Line Plumbing – Model Year 2012 and Newer
1. Disconnect the pressure line from the sprayer valve block. (Figure 3) Connect a 6FJXR
6MJT tee (F02) to the valve block using the 6MJ 8MB fitting (F09).
2. Connect hose H04 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 H01 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.
10.5 Pressure Line Plumbing – Model Year 2011 and Older
1. Disconnect the pressure line from the sprayer valve block. (Figure 4)
2. Insert a 6FJXR 6MJT tee (F02) between the hose and the valve block. Connect hose H01
from the free end of the tee (F02) at the tank port on the sprayer valve block to the
pressure port on the NORAC valve block.
