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 valves are mounted, the hydraulic hoses and fittings can be plumbed.
The plumbing for the hydraulic circuit is shown schematically in Figure 3.
2. Remove the hoses that run between the cap end of the hydraulic tilt cylinder and the steel
line from the valve block.
3. Where the hoses were disconnected from the steel lines, install a 6MJP fitting (F10) onto
the steel line.
4. Connect hose H04 to each of the cap ends of the hydraulic tilt cylinders. Route the hoses
towards the center of the boom, near the valve block.
5. Install the 6MJT fitting (F05) between the two hoses (H04). Attach hose H05 to the
remaining connection of the tee (F05).
6. Install 6FJXR 6MJT fittings (F04) onto the “P” and “T” ports on the NORAC valve block.
7. Install a second 6FJXR 6MJT fitting (F04) onto the tee previously installed into the “T” port
on the NORAC valve block.
8. Connect hose H05 to one of the tee fittings (F04) on the NORAC “T” port.
9. Remove the tank line from the Spra Coupe valve block and attach to one of the tee fittings
installed at the NORAC “T” port using the 6FJ 8MJ fitting (F12). Fitting F12 may not be
needed for all installations.
10. Install hose H02 onto one of the tee fittings (F04) installed at the NORAC “T” port. Route
the free end of hose H02 to the Spra Coupe valve block.
11. Install a 6MJ 6FJX90 fitting (F03) onto the Spra Coupe tank port and attach hose H02 to the
6MJ 6FJX90 fitting (F03) using the 6MJ 8FJX fitting (F11). Fitting F11 may not be needed for
all installations.
12. Remove the Pressure hose from the Spra Coupe valve block and attach to the tee fitting
(F04) installed at the NORAC “P” port.
13. Install hose H02 onto one of the tee fittings (F04) installed at the NORAC “P” port. Route
the free end of hose H02 to the Spra Coupe valve block.
14. Install a 6MJ 6FJX90 fitting (F03) onto the Spra Coupe pressure port and attach hose H02
to the 6MJ 6FJX90 fitting (F03).
15. Install a 6MJ 6FJX90 fitting (F03) onto each of the “B” ports on the NORAC valve block.
16. Attach hose H03 to the “B” ports and route the free end of the hoses to the end of the
Spray Coupe steel lines. These are located towards the outer portion of the center section
frame.
