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 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.
Disconnect the existing “raise” lines from the
valve block. Install the 6FJCN fittings (
F03
)
to the disconnected ports of the valve block.
3.
Connect the “raise” lines to the “B” ports
leading from the NORAC valve block.
4.
Disconnect the accumulators from the “T”
fittings on the Left and Right Tilt boom
cylinders. Remove the fittings attached to the
accumulators.
5.
Between the accumulators and the “T”
fittings on the cylinders, insert the 8MB-8MJ
with orifice adapters (
F08
), 8FJX unions
(
F04
) (
Figure 23
).
6.
Tee the pressure (
H04
) and tank (
H03
) lines
for the NORAC block in to the existing lines
from the existing valve block, using the “T”
fitting (
F02
).
