ASSEMBLY INSTRUCTIONS FOR 38.5 FT., 44.5 FT. & 47 FT.
Refer to illustrations and follow these steps when assembling.
The machine should be placed in an area that allows ample room for assembly in the field position.
CAUTION: For safety purposes, always block equipment while working on it.
MAIN FRAME:
Refer to pages 4-2 and 4-7 or 4-8 when assembling main frame.
Place left and right center frames on stable supports approximately 3 feet off floor. Bolt center frames together using front and rear
splice tubes and secure with (12) 3/4” x 3” bolts, lockwashers and nuts (finger tight only). Use (4) 7/8” bolts on front. Attach cross
tubes (8K1090, 8K1093) as shown. Plates on middle cross tube for attaching lift arm assemblies must face rear of machine. Attach
middle cross tube using REAR set of holes if equipped with multiple hole attachment. Secure each cross tube with (4) 3/4” x 2-1/4”
bolts, (4) 3/4” U-bolts, SAE flat washers, lockwashers and locknuts. Tighten all nuts. Next attach left and right wing frames using 1-1/2”
x 15-1/2” pins. Secure pin through collar with 7/16” x 3-1/2” bolt and locknut.
LIFT ARMS
Install lift arm assemblies on center and wings using 1-1/2” dia. x 15-1/2” pins and secure with 7/16” x 3-1/2” bolts and locknuts.
NOTE: The front center lift arm (8K1186) has (2) 5” long axle tubes and double cylinder attach.
WHEELS
Insert axle and hub assemblies. Apply good quality anti-seize to axles before inserting into receiver tubes. Retain with 1/2” x 4-1/2”
bolts and locknuts in outside position. Install wheel and tire assemblies, retain with wheel nuts (torque required: 240 ft-lbs).
A-FRAMES
Mount A-Frame assemblies above lift arm assemblies as shown. The center of the A-Frame assemblies (8K1224, 8K1242) on the rear
sections should be 16” from the center of pin hole.
On the wing A-Frame assemblies (8K1242), the side with the hose clamps should face the center of the machine.
Mount front center A-Frame (8K1212) using (4) 3/4” bolts, (2) 3/4” U-bolts and hardware. Install the adjustable cylinder bolts next. Set
the nuts so the bolts are in the middle of the adjustment. Insure that cylinder attach holes are aligned when eye bolts are tightened.
These will be readjusted later, see Field Operation section.
MAIN LIFT HYDRAULIC SYSTEM
Refer to page 4-9 when assembling the main lift hydraulic system.
The front center lift arm (8K1186) has two cylinder attach locations. Use rear cylinder attach hole. Cylinder attach location can be
changed based on field adjustments. Connecting front center cylinder to rear hole will lower front end of disk in transport position.
Attach cylinders to the adjustment bolts and lift arms as shown. Note the different sized cylinders. Cylinders must be in their proper
location. Install all fittings into cylinders. Route hoses as shown. Use clamps provided to secure hoses to frame. Tighten hose hold-
down clamps enough to retain hoses but loose enough that clamps can be turned by hand. Hydraulic hoses will expand and shorten
when pressurized. Tighten all fittings.
IMPORTANT: Allow enough hose at hinge points to avoid pinching or stretching the hose.
WING LIFT HYDRAULIC SYSTEM
Refer to page 4-10 or 4-11 when assembling the wing lift system. 38-1/2’ - 47’ disks use two hydraulic cylinders per wing. Mount wing
lift cylinders on the front and rear cross tubes. Mount lift cylinders to adjustment bolts and route hoses as shown. Fill lift cylinders with
oil before attaching lift linkage. Position adjustment bolts by starting end nuts so they are flush with bolt. Once lift cylinders have been
filled with oil and cycle smoothly, connect wing lift linkage. Raise wings by fully retracting lift cylinders.
CAUTION: Stand clear whenever raising or lowering wings.
With Part 1 lift cylinders fully retracted, tighten the end (inside) adjustment nut until the holes for the transport pin lock align. Then tighten
outside nut to lock in place. Adjust Part 2 wing lift cylinders and stop bolts on 47’ so wings are level when cylinders are fully extended.
Insure that cylinder attach holes are aligned when eye bolts are tightened. Lower wings back to field position for gang mounting.
