9.5 Hydraulic Plumbing
From this point on in the installation the booms will be inoperative until the
hydraulics 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 NORAC supplied hoses (H02) to the Pressure (“P”) and Tank (“T”) ports on
the NORAC valve block (V01). Tee hoses H02 (“P” and “T” lines) into the ports on the
sprayer valve block with 6FORXR-6MORT fittings (F03) and 6MB-6MOR fittings (F05). The
elbow fittings currently in place must be replaced by the 6MB-6MOR fitting (F05).
3. Disconnect the existing hoses from the tilt cylinders. Remove the existing 90 degree fitting
on the rod end of each cylinder. Install a 6FORXR-6MORT fitting (F03) onto the ports of
each tilt cylinder. Reconnect the cylinder hoses and 90 degree fittings to the newly installed
tees.
4. Connect one end of hoses H01 to the F03 fittings on the LEFT tilt cylinder. Connect the
other end of hoses H01 to the NORAC valve block “A” and “B” ports.
5. Connect one end of hoses H03 to the F03 fittings on the RIGHT tilt cylinder. Connect the
other end of hoses H03 to the NORAC valve block “A” and “B” ports.
6. The “raise” lines must be connected to the "B" ports of the NORAC valve block. The
“lower” lines must be connected to the "A" ports of the NORAC valve block.
7. Connect one end of the hydraulic hoses (H72) to the NORAC expansion valve block’s “A”
and “B” ports. Route the other end of the hoses to the roll cylinder previously installed.
Attach the hose connected to the “B” port of the expansion block to the rod end of the
cylinder. Connect the hose connected to the “A” port of the expansion block to the cap
end of the cylinder.
8. Attach hose H02 to the “B” port on the 3 rd station of the block. Route the free end of the
hose (H02) to the John Deere main lift tee, which is located on the right hand end of the
John Deere valve block (Figure 37).
