10.5 Hydraulic Plumbing: Double Acting
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 5.
2. Disconnect the tilt raise and lower lines from the sprayer valve block and insert the four
tees (F02) between the hoses and the valve block.
3. Connect four hydraulic hoses (H02) from the free ends of the tees to the NORAC valve
block. The raise lines must be connected to the “B” ports and the lower lines must be
connected to the “A” ports.
4. If there are any accumulators on the tilt hydraulic circuits, ensure there is a 2-way orifice in
the accumulator fitting.
5. There must be no other orifices in the hydraulic circuit between the NORAC valve block
and the tilt cylinders.
6. Disconnect the pressure and tank lines from the sprayer valve block and insert the two tees
(F01) between the hoses and the valve block.
7. Connect two hydraulic hoses (H01) from the free ends of the tees to the pressure and tank
port on the NORAC valve block.
