8.3 Hydraulic Plumbing
From this point on in the installation the booms will be inoperative until the
hydraulics are fully installed.
1. After the NORAC valves are mounted, the hydraulic hoses and fittings can be plumbed. The
plumbing for the hydraulic circuit is shown schematically in Figure 3.
2. Connect the NORAC supplied hoses (H04) to the pressure (P) and tank (T) ports on the
NORAC valve block (V01). Route both of these lines to the sprayer valve block.
3. Disconnect the existing pressure (P) and tank (T) lines from the sprayer valve block. Install
the 6MB-8FB (F05) fittings into the “P” and “T” ports.
4. Connect the tee fittings (F04) to the fittings (F05) on the “P” and “T” ports of the sprayer
valve block.
5. Connect H04 from the “P” port on the NORAC block to the tee fitting (F04) on the “P”
port of the sprayer block.
6. Connect H04 from the “T” port on the NORAC block to the tee fitting (F04) on the “T”
port of the sprayer block.
7. Connect the existing pressure and tank hoses to the tee fitting (F04) on the appropriate
port using F03.
8. The existing hoses that run to the boom tilt cylinders should be disconnected from the
sprayer valve block and reconnected to the NORAC valve block.
a) The “raise” lines from the side of the boom tilt cylinders, which raise the booms, must
be connected to the "B" ports of the NORAC valve block. The ports on the sprayer
block must then be plugged with the 6MBP plugs (F02).
b) The "A" ports of the NORAC block must be connected to the “lower” lines of the
cylinders. The ports on the sprayer block must then be plugged with the 6MBP plugs
(F02).
