10.3 Hydraulic Plumbing
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. Install the 6MOR 6FORX90 fittings (F02) onto the previously installed fittings F03 on the
“P”, “T” and “B” ports of the NORAC block.
3. Disconnect the “raise” lines from the Miller valve block. Install the tee fittings (F04)
between the valve block and the disconnected lines.
4. Connect the hoses (H02) to the open ports on F04. Connect the other end of hoses H02
to fittings F02 installed on the “B” ports of the NORAC block. The “raise” lines must be
connected to the “B” ports on the NORAC block.
5. Remove the existing plugs on the end of the Miller valve block for both the pressure and
tank lines. Insert the 8MB 8MOR fittings (F01) into both ports.
6. Connect one end of hoses H01 to F01. Connect the other end of H01 to fittings F02
installed on the pressure (“P”) and tank (“T”) ports on the NORAC valve block.
7. 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.
8. Remove the 8MB 8MOR fitting from the wing accumulators.
9. Install an 8MOR 6MOR fitting (F07) into the wing accumulator.
10. Attach a 6FOR 8MOR fitting (F06) onto fitting F07 with the inline orifice (F08) 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 F08 has the o-ring (F09) installed.
