SECTION 2 - ASSEMBLY
2-58
HYDRAULIC SYSTEM
Install cylinder hydraulic fittings and hydraulic hoses between cylinders.
HITCH TUBES
Position hitch tubes on top of center section. Attach hitch tubes to center section with ¾” u-bolts,
lockwashers and nuts. Connect hitch tubes with hitch extension, hitch channel (8C5050) and hitch
piece (8D0720) at front of machine using hardware provided.
46’ to 50’ ONLY
Install front cross brace below hitch tubes with ½” and ¾” u-bolts. Locate 20” (center to center)
ahead of main frame front pivot. IMPORTANT: All three wing hinge points must be in line. If hinge
points are not in line, loosen u-bolts, position braces correctly and retighten.
WING BRACES
Install wing braces to front center pivots with 1-1/4” pins. Secure to wing with ¾” u-bolts.
HYDRAULIC HOSES TO TRACTOR AND TIRES
Install hydraulic hoses and fittings to front of machine. Secure hoses with clamps provided. Do
not over tighten, hydraulic hoses expand and shorten when pressurized. Install wheels and tires.
Tighten wheel bolts to 122 ft-lb torque.
CHARGE HYDRAULIC SYSTEM
Block Wing Lift Hydraulic Cylinders so rods can fully extend without contacting anything. Connect
hydraulic tips to tractor hydraulic couplers. Extend and retract cylinders until air is purged from
hydraulic system. Attach rod end of part 1 wing lift cylinders to wing lift slots with 1” X 7” bolt, flat
washer, bushings and lock nut. Attach rod end of part 2 wing lift cylinders to lift linkage. Do not
overtighten lock nuts as rod end of wing lift cylinders must slide freely in lift slot and bolts must rotate
freely. Raise and lower machine. Watch so hydraulic hoses do not tighten or get pinched, adjust
hoses if necessary. Adjust part 1 wing lift cylinder eye bolts so wings rest on center frame Wing
Stops (8C5140) during transport. Adjust part 2 wing lift cylinders so part 2 wings rest on support
pipe. Tighten all Eye Bolts. Insure that cylinder attach holes are aligned when eyebolts are tight-
ened.
C-SHANKS
Mark frame with coil locations shown in layout drawing. Position C-Shank clamps (8C5820) 9-1/2”
center to center at these locations. Install C-Shanks (8K4392) and secure with hardware provided.
COIL/CHOPPER ASSEMBLIES
Pre-assemble Pull Frames. Secure pillow block to adjustment arm with 1/2” u-bolt and hardware.
Secure bearing to coil shaft with set screws and snap ring. Attach Coil and Pull Frame assemblies
to C-Shanks using ¾” U-bolts (8C1720) and hardware. Note: Left and Right hand wound coils can
be identified by comparing to Left and Right hand bolt threads.
SMV sign, Wing Transport Locks, Main Transport Lock, ID & Safety Decals and Safety Lighting
Install SMV sign at rear center of machine. Install Wing and Main transport locks. Install decals.
Install Safety Lighting components. Where possible, run wiring harnesses next to hydraulic hoses.
