8.3 Hydraulic Plumbing
From this point on in the installation the booms will be inoperative until the
hydraulics are fully installed.
Ensure there are no other orifices present in the circuit between the NORAC
valve block and the boom cylinders.
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. Disconnect the “raise” lines from the sprayer valve block and connect to the “B” ports of
the NORAC valve block.
3. The open ports on the sprayer block must then be plugged with 6MBP plugs (F02).
4. Connect the NORAC supplied hoses (H04) to the pressure (P) and tank (T) ports on the
NORAC valve block. Route both of these lines to the sprayer’s valve block and tee in to
the existing “P” and “T” lines, respectively, using the 8FJXR-8MJT fittings (F03).
5. Remove existing couplings from between the existing accumulator and tee fitting on both
cylinders.
6. Insert the 6MB-6MJ orifice fittings (F07) and 6FJX union fittings (F04) between the tee and
accumulator as shown in Figure 3.
