GENERAL ASSEMBLY SAFETY PRACTICES

SECTION 2 - ASSEMBLY
2-2
ASSEMBLY INSTRUCTIONS FOR 16 FT. - 28.5 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 eld position.
CAUTION: For safety purposes, always block equipment while working on it.
MAIN FRAME:
Refer to pages 2-4 thru 2-28 and Parts Section when assembling main frame.
Place left and right center frames on stable supports approximately 3 feet off oor. Bolt center frames together using
front splice tube and rear cross tube.
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.
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 5/8” wheel nuts (torque
required: 240 ft-lbs).
A-FRAMES
Mount A-Frame assemblies above lift arm assemblies as shown.
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.
WING LOCKS
Install Locks on rear cross tube, slide as far away from center as possible, tighten hardware.
MAIN LIFT HYDRAULIC SYSTEM
Refer to page 4-1 or 4-2 when assembling the main lift hydraulic system.
Attach cylinders to adjustment bolts and lift arms as shown. Note the different sized cylinders. Cylinders must be in their
proper location. Install all ttings 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 ttings.
IMPORTANT: Allow enough hose at hinge points to avoid pinching or stretching the hose.

SECTION 2 - ASSEMBLY
2-3
WING LIFT HYDRAULIC SYSTEM
Refer to page 4-5 or 4-6 when assembling the wing lift system. Mount lift cylinders to adjustment bolts and route hoses
as shown. NOTE: CYLINDER PORTS MUST BE FACING DOWN. Fill lift cylinders with oil before attaching lift linkage.
Position adjustment bolts by starting end nuts so they are ush with bolt. Once lift cylinders have been lled with oil and
cycle smoothly, connect wing lift linkage. Adjust eye bolts after gangs have been mounted.
CAUTION: Stand clear whenever raising or lowering wings.
HITCH
Attach hitch using (2) 1-1/2” dia. x 10-5/8” pins and secure with 7/16” x 3-1/2” bolts and locknuts.
GANG MOUNTING
Refer to gang layout on page 4-8 through 4-11.
On Diamond Disk position gangs so notched blades are located at rear center of disk.
Start from the center and work towards the outside when hanging gangs. Lift gang up to the frame close to the correct
location.Secure with 7/8” x 3” bolts, lock washers and locknuts.
MOUNTING WEIGHT PACKAGE
Mount weight packages on outside of wings in location that will not interfere with disk gang or tire travel. Install 1/2 weight
packages (6 suitcase weights with mounting angles and hardware) by positioning mounting angles 8-1/2” apart. Secure
with 3/4” U-bolts, lockwashers and nuts. Fully tighten hardware on one mounting angle. Hand tighten mounting hardware
on second mounting angle, this must be free to slide. Insert one 1” x 10-1/2” bolt through both mounting angles, turn 1”
nut onto this bolt until threads are ush with outside of nut. Spread mounting angles as much as 1” bolt and nut will allow.
Lift suitcase weights (8K9230) into position, slide slotted hole of weight over 1” bolt. Continue to slide weight past corner
of slot until it reaches the end of the slot, at this location the hole without slot will line up with the second hole in the
mounting angles. Repeat procedure with remaining suitcase weights. Insert second 1” x 10-1/2” bolt through angles
and weights. Secure second 1” bolt with lockwasher and nut, fully tighten. When second 1” bolt is tight, remove the nut
from rst bolt and add the lockwasher. Fully tighten all remaining nuts.
Caution: Each suitcase weight (8K9230) weighs 70#, use extreme care when handling them.
SAFETY
Install SMV mounting bracket at machine center. Install remaining decals at locations shown on page 1-6. Install Safety
Light Kit, refer to breakdown on page 4-24.
MOUNT REAR ATTACHMENT (OPTIONAL)
See Page 4-15 or 4-22.
