ASSEMBLY INSTRUCTIONS
Center Disc Gangs
There are several ways to install the gangs on the 7550.
It is recommend to install the front gangs first to keep the
front end of machine from coming up uncontrolled. If a
hoist is available, installing the center frame gangs before
installing the wings or the hitch is one way of assembling
the disc gangs on the center frame. The more common
method is to install the hitch, wings, leveler, and route the
hoses for the lift system so the machine can be raised
and lowered to allow getting the gangs under the frame.
For ease of installation, do not mount the fold
cylinder brackets to the center frame until the center
gangs and the gang adjust links are assembled.
Again with this method install the left front gang first, right
front , right rear, and then the left rear center. This will
keep the most clearance to allow getting them installed.

DANGER
1. Install the left front disc gang assembly by moving
disc gang assembly to proper frame position
( See
Figures 3-5 .) Install gang pivot pin through gang
pivot tube of gangbar, there are notches that will
need to be aligned so the pin will not rotate in the
gang bar. Install the 3” stainless steel thrust washer
over the gang pivot pin, and pin will go on through the
gang pivot mount welded to the center frame inside
the hinges. Install the 1-13/16 diameter thrust
stainless steel washer to the threaded end of the
gang pivot pin along with the gang pivot nut. If the top
bushing in the center frame pivot comes out a little
while the pin is going through, just put the gang pivot
nut on and hand tighten down to press it back into
place. Next loosly install the gangbar slide and blue
washer with a 1-13/16” diameter hole and 1-3/4”
slotted nut in the middle of the center frame to keep
the end of the gang from falling.
2. Proceed to install the remaining three gangs-right
front, right rear, and left rear in the same way.
3. With all the center frame gangs installed, set the
center frame or the whole machine down so the
gangs are setting on the floor. Remove the four
gangbar slide that are in the center of the frame so
the gang connector links can be installed.
4. The front gangs have a distance of 26” from center to
center of the gangbar pivot shafts sticking up, move
gangs to where this is close and the gangs are close
to the front of the machine as shown in
( See
Figures 3-4 .) Assemble the front bearing halves and
insert the 3/4-10 x 9” bolts through the front
connector. Assemble the rear bearing halves and
insert the 3/4-10 x 10” bolts through the connector
and into front link weldment. Tighten these four bolts
alternating sides to tighten the cast bearings up
evenly. With both bearings tight, install a stainless
steel washer on top of the bearing inserts and
reinstall the gang bar slides, blue washers with
1-13/16” diameter hole and slotted nuts.
5. The rear gangs have a distance of 12” from center to
center of the gangbar pivot shafts sticking up, move
gangs to where this is close and the gangs are close
to the rear mount that is assembled with the frame.
Assemble the front and rear bearing halves with
clamp plates and insert the ¾-10 x 9 bolts through
the connector with the nuts being on the inside.
Tighten these four bolts alternating sides to tighten
the cast bearings up evenly. With both bearings tight
install a stainless steel washer on top of the bearing
inserts and reinstall the gang bar slide weldments,
blue washer with 1-13/16” diameter hole and slotted
nuts.
6. Tighten down all eight of the slotted nuts on the
center frame using the disc gang wrench provided
on the center frame. Tighten to 200 ft-lbs and then
back off to the nearest slot in nut.
IMPORTANT
Grease the zerk down inside of four gang pivot
pins until grease is purged from the pivot joint.
7. Install a 3/8 x 3 clevis pin and 1/8 hairpin to prevent
gang pivot nut from loosening
( See Figures 3-5 )
.
Disc blades are extremely sharp. Exercise
extreme care when working on or near disc
blades. Do not allow discs to roll over or fall onto
any bodily part. Do not allow wrenches to slip
when working near disc blades. Never push
wrenches toward disc blades. Do not climb over
machine above disc blades. Failure to stay clear
of disc blade edges can cause serious personal
injury or death.
