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. Remove the 90-degree fittings from the sprayer valve block and plug the ports with the

6MB plugs (F02).

3. Connect the 6FORXR 6MORT (F07) fittings to the 6MOR 6FORX90 (F06) fittings on the

“A” ports of the NORAC block.

4. Connect the “lower” line hoses from the cylinders to one end of the 6FORXR 6MORT

(F07) fitting. Connect the supplied hoses (H04) to other end of the 6FORXR 6MORT (F07)

fitting.

5. Connect the free ends of H04 to the “A” ports (wing lower) of the sprayer valve block with

F05.

Use the supplied hoses (H07 and H08) if the existing lines are too short to

reach the block.

6. The “raise” lines from the side of the cylinders, which raise the booms, must be connected

to the “B” ports of the NORAC valve block.

7. Connect hoses H06 to the pressure and tank ports on the NORAC valve block.

8. Tee the pressure and tank lines (H06) into the existing lines from the existing valve block

using the 8FORXR 8MORT (F04) fittings and 8MOR 8MB (F03) fittings.
