10.3 Hydraulic Plumbing
From this point on in the installation the booms will be inoperative until the
hydraulics are fully installed.
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. Disconnect the junction of the steel hydraulic line and the hose of the Spra-Coupe circuit.
Connect a 6FJXR 6MJT tee fitting (F04) between the steel line and the hose.
3. Connect one end of the hoses H03 to the 90 degree fittings (F03) installed on the “A” and
“B” ports of the NORAC block. Route hoses H03 from the NORAC valve block to the tee
fittings (F04).
4. The “B” ports leading from the NORAC valve block are the “raise” lines, and must be
connected to the boom raise cylinders via the existing lines and the tee fittings.
5. The “A” ports leading from the NORAC valve block are the “lower” lines, and must be
connected to the boom lower cylinders via the existing lines and the tee fittings.
6. Remove the existing Spra-Coupe Pressure and Tank lines from the Spra-Coupe valve block
and fit them to the NORAC Pressure (P) and Tank (T) ports using the tee fitting (F02).
Attach the two hoses (H02) to F02.
7. Use the 90 degree 6MJ 6FJX90 fittings (F03) to attach the other end of H02 to the Spra-
Coupe Pressure and Tank ports.
