4.6.2 Valve Mounting
1. Mount the NORAC valve (V01) on the
sprayer using the valve mounting
bracket.
2. Screw short side of the threaded rods
into the bottom of the valve block at
least 3/8". The valve mounting holes are
drilled and tapped 3/8 NC-1" deep.
3. Tighten the Hex nuts to hold the rods.
4. Put the mounting bracket on the other
side of the tube and tighten with the
spring washers and the Hex nuts.
5. Cut excess off of the studs, if necessary.
If using bolts, the bolts should
thread into the valve block at
least 3/8". The valve mounting
holes are drilled and tapped 3/8
NC-1" deep. The rule of thumb
for bolt length is 1-1/2" longer
than the tube size.
You must ensure no hydraulic
components will interfere with
any sprayer parts or be pulled
tight at any time.

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. Connect the 6FORX hose end on the
NORAC supplied hoses (H01) to the
Pressure port and the Tank port on the
NORAC valve block.
3. Tee the “P” line to the pressure port
and the “T” line to the tank port on the
sprayer valve block using the 8MB
8MOR fittings (F01).
4. Disconnect the “raise” lines from the
sprayer valve block and connect them
to the "B" ports of the NORAC valve
block. Plug the sprayer ports with the
8MBP plugs (F12).
The following steps are only for
sprayers with accumulators on the tilt
cylinders.
5. Remove the 8MB 8MOR fitting from the
wing accumulators.
6. Install an 8MOR 6MOR fitting (F07)
into the wing accumulator.
7. Attach a 6FOR 8MOR fitting (F06) onto
fitting F07 with the inline orifice (F08)
between the two fittings. The inline
orifice is the orifice with a groove on
one side and an o-ring (F09) installed
on the other side.
