10.3 Hydraulic Plumbing
If the sprayer valve block has a serial number 21.12732 and lower, refer to
Appendix A: Hydraulics for Older Sprayers for additional fittings that may be
necessary.
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.
2. The “raise” lines must be connected to the “B” ports of the NORAC valve block. Insert
the 8FORXR 8MORT tee fittings (F11) between the Nitro valve block and the existing
“raise” lines.
3. Install an 8MOR 8FORX90 fitting (F14) onto the open ports on F11. Connect the straight
end of hoses (H01) to F14. Connect the 45 end of hoses H01 to the “B” ports of the
NORAC block.
4. Remove the existing plugs on the end of the Nitro valve block for both the pressure and
tank lines. Insert the 8MB 8MOR fittings (F04) into both ports.
5. Install an 8MOR 8FORX90 fitting (F14) onto F04. Connect the straight end of hoses H01
to F14. Connect the 45 end of H01 to the pressure and tank ports on the NORAC valve
block.
6. Ensure there are no other orifices present in the circuit between the NORAC valve block
and the boom cylinders.
The following steps are only for sprayers with accumulators on the tilt cylinders.
1. Remove the 8MB 8MOR fitting from the wing accumulators.
2. Install a 6MOR 8FORX fitting (F05) into the wing accumulator.
3. Attach an 8MOR 6FOR fitting (F07) onto fitting F05 with the inline orifice (F06) between
the two fittings. The inline orifice is the orifice with a groove on one side and an o-ring on
the other side. Ensure that F06 has the o-ring (F13) installed.
