4.3.3 Hydraulic Plumbing
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 must be connected to
the “B” ports of the NORAC valve
block. Insert the “T” fittings (F02)
between the sprayer block and the
“raise” lines. Connect hoses to the open
ports on F02 and the “B” ports of the
NORAC block.
The “T” fittings are inserted into
the hydraulic circuit to allow the
NORAC valve block to control
the cylinders in parallel with the
existing system.
3. Tee the pressure (“P”) and tank (“T”)
lines for the NORAC block into the
existing lines from the valve block, using
the “T” fitting (F03).
4. Connect the “A” and “B” ports on the
expansion block to the linear roll
cylinder, as shown in Figure 3.
Ensure that there are no other
orifices present in the circuit
between the NORAC valve block
and the boom cylinders.
Ensure that no hydraulic
components will interfere with
any sprayer parts or be pulled
tight at any time.
Ensure all air is bled from the roll
cylinder hydraulic lines before
proceeding.
