SECTION 2 – HYDRAULIC SET-UP OF WING LIFT CIRCUIT

Note: The Summers Superchisel uses in-line restrictors to control hydraulic flow of the part 2 wing lift

cylinders and extension (lowering) of the part 1 wing lift cylinders. It is important that restric-

tors are installed in the wing lift circuit. This chisel plow uses sequencing valves to insure

the wings fold properly. After installation, it may be necessary to change the pressure level

of these valves for the wings to fold properly. See page 2-23 or 2-24 for Wing Lift layout.

1. Install fittings into manifold block (8W1360) as shown in drawing.

– Install eight 8J5500 - 9/16” ORB x 6 JIC(M) and two 8J6000 - 9/16” ORB x 6 JIC 90°(M) fittings

into manifold block (8W1360). Install fittings as shown.

– Attach manifold block onto the front center of chisel plow. There are two bolts on the top of

the cross member for the cylinder support that hold the block. Secure with lock nuts.

2. Install fittings into sequencing valves (8T8100) as shown in drawing.

– Install 8J6010 - 3/4” ORB x 6 JIC(M) x 90 adapters into port #1 on the valve bodies. This is

the main supply port for each valve.

– Install 8J5500 - 9/16” ORB x 6 JIC(M) fittings into port #3 on the valve bodies. This is the drain

port for each valve.

– Install 8J5620 - 3/4” ORB x 6 JIC(F-SW) fittings into port #2 and then attach one 8J5300 - 6

JIC(M) T and two 8J5700 - 6 JIC(F-SW) x 6 JIC(M) x 90 adapters to each of these fittings.

This is the supply to the cylinders that are being sequenced.

– Place the sequencing valves behind the cross member the manifold block is attached to. Posi-

tion so both port #3’s are toward the center of the machine.

3. Install hoses that supply base end of part 1 wing lift cylinders.

– Install 35” hose from one right hand port of the manifold block to the base end of both front 5

x 36” cylinders.

– Connect base end of rear 5 x 36” cylinders to front cylinders with 70” hoses.
