SECTION 2 – HYDRAULIC SET-UP OF WING LIFT CIRCUIT
6. Extension of part 2 wing lift cylinders is controlled with a sequencing valve. This step will show
proper plumbing for this part of the wing lift circuit.
– Connect an 18” hose from the right hand end of the manifold block to port #1 on the right hand
sequencing valve.
– Connect another 18” hose from the middle port on the left hand side of the manifold block to
port #3 on the sequencing valve. This hose will allow draining of the valve.
– Connect a 204” and a 228” (228” and 252” on 56’-60’) hose to the T on port #2 of the sequenc-
ing valve. The longer hose will go to left side of the machine.
– Route these hoses to front 4-1/2 x 16” cylinders on wings along second rank.
– Connect a 6 JIC(M) T to the end of each of these hoses.
– Connect a 96” hose to each T. Be sure that 1/16” restrictors are installed with fittings shown.
– Connect 96” hoses to the base end of each rear 4-1/2 x 16” cylinder as shown.
7. Connect two 330” hoses to front side of manifold block.
– Route these hoses to front of hitch along same path as depth control hoses. Leave slack by
the hitch pivot.
– Install 3/4” ORB x 6 JIC(M) adapters and ISO tips onto ends of 330” hoses.
– Install yellow nylon ties by tips and closest cylinder to identify Wing Lift circuit.
– Use nylon ties to hold hoses away from pinch points.
NOTE: Hydraulic hoses will expand and shorten when pressurized. Do not overtighten hose
clamps. Leave some slack between all clamps.
