4.6.3 Hydraulic Plumbing
WARNING!
From this point in the installation
the booms will be inoperative until
the electronics are fully installed.
You must ensure no hydraulic
components will interfere with
any sprayer parts or be pulled
tight at any time.
You must also 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. The “raise” lines from the side of the
boom tilt cylinders, which raise the
booms, should be disconnected from
the sprayer valve block. Then, they must
be reconnected to the “B” ports of the
NORAC valve block.
3. The opened 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.
