4.6.3 Hydraulic Plumbing
WARNING!
From this point in the installation the
booms will be inoperative until the
electronics 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) into
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).
6. Attach hose H05 to the remaining
connection of the tee (F05).
7. Install 6FJXR 6MJT fittings (F04) onto the
“P” and “T” ports on the NORAC valve
block.
8. Install a second 6FJXR 6MJT fitting (F04)
onto the tee previously installed into the “T”
port on the NORAC valve block.
9. Connect hose H05 to one of the tee fittings
on the NORAC T port.
10. Remove the Pressure hose from the Spra-
Coupe valve block.
11. Install the Spra-Coupe pressure hose onto
the tee fitting, installed at the NORAC “P”
port.
12. Install a 6MJ 6FJX90 fitting (F03) onto the
Pressure connection at the Spra-Coupe
valve block.
13. Connect hose H02 to the Spra-Coupe
Pressure port and route the other end to
the NORAC valve block. Install the hose
onto the tee installed in the “P” port on the
NORAC valve block.
14. Remove the tank line from the Spra-Coupe
valve block.
15. Attach the tank line to one of the tee fittings
installed at the NORAC “T” port.
16. Install hose H02 onto one of the tee fittings
installed at the NORAC “T” port.
17. Route the free end of hose H02 to the Spra-
Coupe valve block.
18. Install a 6MJ 6FJX90 fitting (F03) onto the
Spra-Coupe Tank port.
19. Install hose H02 onto the 6MJ 6FJX90 fitting
on the Spra-Coupe tank port.
20. Install a 6MJ 6FJX90 fitting onto each of the
“B” ports on the NORAC valve block.
21. 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.
22. Disconnect the connection where the flex
line and steel line meet. Be sure this is the
line that connects to the gold accumulator
block at the tilt cylinder.
23. Install a 6FJXR 6MJT fitting (F04) onto the
steel line and then attach the flex line to the
tee fitting.
