Hydraulic Plumbing
From this point on in the installation the booms will be inoperative until the
hydraulics are fully installed.
After the NORAC valve is mounted, the hydraulic hoses and fittings can be plumbed.
1.
The plumbing for the hydraulic circuit is shown schematically in Figure 2.
2.
Insert two (2) 6FORXR-6MORT tees (F13) between the NORAC valve block and the
existing tee fittings on the “B” ports of the NORAC valve block.
3.
Connect hoses H06 to the tees (F13).
4.
Install four (4) 6MB-6MJ fittings (F12) onto the ports on the wing roll cylinder (H20).
5.
Install four (4) 6MOR-6FORX90 fittings (F14) onto the F12 fittings.
6.
Install two (2) 6FORXR-6MORT tees (F13) onto the F14 fittings on the “1” and “2” ports
of the wing roll cylinder (H20).
7.
Connect hose H06 from the F13 tee on the right “raise” line to the “2” port on the wing
roll cylinder (H20).
8.
Connect hose H06 from the F13 tee on the left “raise” line to the “1” port on the wing roll
cylinder (H20).
9.
Connect hose H06 between the “3” port on the wing roll cylinder (H20) and the “B” port
on the NORAC expansion valve block.
10.
Connect hose H06 between the “4” port on the wing roll cylinder (H20) and “A” port on
the NORAC expansion valve block.
11.
Connect hoses H13 to the free ends of the F13 tees on the “1” and “2” ports of the wing
roll cylinder.
12.
Connect the other end of hoses H13 to the accumulators (H12) using 6MB-6MOR fittings
(H14).
