ASSEMBLY INSTRUCTIONS FOR 18.5 FT. THRU 32.5 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 4-3 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 front and
rear cross tubes (8K1081, 8K1082) as shown. Plates on front cross tube for attaching lift arm assemblies must face rear of machine.
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 pins through collar with 7/16” x 3-1/2” bolts and locknuts.
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: Wing lift arm assemblies (8K1134) are 14-1/2” shorter than rear center lift arm assemblies (8K1152). The
front center lift arm (8K1146) has (2) 5” long axle tubes and double cylinder attach.
WALKING TANDEM ASSEMBLIES (Rear Center Only)
Check inside surface of walking tandem assemblies (8T4132). A 3-3/4” diameter surface around the 1-1/2” dia. pivot hole must be
smooth and burr-free. Remove any welding spatter or roughness prior to further assembly. Install snap rings (8K1920) past grooves
of lower pivot tube on the rear center lift arm assemblies. Install V-seal over lower pivot tubes until solid side is against snap ring.
Protect lip of V-seal during assembly.
Install walking tandem assemblies to the bottom of rear center liftarms. Mount so axle closest to the center of machine is towards rear.
Insert pivot pin (8T3620) through walking tandem assembly and lift arm. Retain with 7/16” x 3-1/2” bolts and locknuts. Push V-seal
against walking tandem assembly and secure by placing snap ring into groove.
WHEELS
Insert axle and hub assemblies. Apply good quality anti-seize to axles before inserting into receiver tubes. Retain with 1/2 x 3-3/4”
bolts and locknuts in outside position. Install wheel and tire assemblies, retain with 9/16” wheel bolts (torque required: 170 ft-lbs) or
5/8” 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 (8K1221) on the rear center
section should be 22-1/2” from the center of pin hole. On the wings, this measurement is 15-1/2”.
NOTE: On the center A-Frame assembly (8K1221), the longer arm must face the center of the disk frame.
On the wing A-Frame assemblies (8K1232 or 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 nuts
so 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 pages 4-4 and 4-5 when assembling the main lift hydraulic system. The front center lift arm (8K1146) 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 adjustment bolts and lift arms as shown. Note the different sized cylinders. Cylinders must be in their proper loca-
tion. 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.
