10.3 Hydraulic Plumbing
From this point on in the installation the booms will be inoperative until the
hydraulics are fully installed.
The factory CASE main lift accumulators must be charged to their recommended
setting for proper operation of the UC5 Spray Height Control system. Even on
new sprayers, the charge pressure should be checked before proceeding with the
installation
1. After the NORAC valve is mounted, the hydraulic hoses and fittings can be plumbed. The
plumbing for the hydraulic circuit is shown schematically in Figure 3.
2. Connect the four 90 degree fittings (F07) to the “A” and “B” ports on the NORAC valve
block. Attach the four 6FORXR-6MOR tee fittings (F03) to the 90 degree fittings on the
NORAC block.
3. Connect the “lower” line (the “A” line) hoses from the cylinders to one end of the
6FORXR-6MORT tee fitting on the NORAC “A” ports.
4. Connect the “raise” line (the “B” line) hoses from the cylinders to one end of the 6FORXR-
6MORT tee fitting on the NORAC “B” ports.
5. Install the four supplied hoses (H01) between the tee fitting and the Case valve block. Use
the 6MB-6MOR adapter (F05) to connect the hose to the Case valve block.
6. Tee the pressure and tank lines for the NORAC valve block into the existing “P” and “T”
lines on the Case sprayer block. Use the 8FORXR-8MORT (F06) fittings and the 8MOR-
8MB (F04) adapters.
