4.6.3 Hydraulic Plumbing
WARNING!
From this point in the installation the
booms will be inoperative until the
electronics 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. Install the 6MB-6MJ fittings (F05) into
the “P” and “T” ports on the NORAC
valve block and tighten to 18 ft-lbs.
3. Connect a 6FJX90 hose end on the
NORAC supplied hose (H02) to the
Pressure port on the NORAC valve
block.
4. Tee the “P” line to the pressure port on
the sprayer valve block using the 6FJXR-
6MJT fitting (F04).
5. Connect the 6FJX90 fitting on hose
H04 to the Tank port on the NORAC
valve block.
6. Tee in the “T” line to the tank port on
the sprayer valve block using the 8FJXR-
8MJT fitting (F07).
7. The “raise” lines must be connected to
the "B" ports of the NORAC valve
block. Connect the 6FJX90 hose ends
on the NORAC supplied hoses (H02)
to the “B” ports of the NORAC valve
block.
8. Tee the other ends of H02 into the
ports of the sprayer valve block,
connecting to the boom raise cylinders
with the 6FJXR-6MJT fittings (F04).
The “T” fittings are inserted into
the Apache hydraulic circuit to
allow the NORAC Valve block to
control the cylinders in parallel
with the existing system.
