SECTION 2 – HYDRAULIC SET-UP OF WING LIFT CIRCUIT
4. Retraction of part 1 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 left hand end of the manifold block to port #1 on the left hand
sequencing valve.
– Connect another 18” hose from the middle port on the right hand side of the manifold block to
port #3 on the left sequencing valve. This hose will allow draining of the valve.
– Connect a 60” and an 84” hose to the T on port #2 of the left sequencing valve. The 84” hose
will go to right side of the machine. Route hoses to rod end of the front 5 x 36” cylinders.
– Install fitting shown and a 6 JIC(F) x 6 JIC(M) 1/16” restrictor to rod end of each 5 x 36” cylin-
der.
– Connect rod end of rear 5 x 36” cylinders to front cylinders with 70” hoses.
5. Plumbing rod ends of part 2 wing lift cylinders.
– Connect a 228” (252” on 56’-60’) hose to two rear ports on the left hand side of the manifold
block.
– Route these hoses to front 4-1/2 x 16” cylinders on wings along second rank.
– Install a 6 JIC(M) T at the end of these hoses.
– Connect 124” hose on one side of each T. Be sure that 1/16” restrictors are installed with fit-
tings shown.
– Connect 124” hoses to rod end of rear 4-1/2 x 16” cylinders as shown.
