Disc Gang Assembly Procedure
A disc gang consists of an axle on which disc blades, spacer spools
and bearings are mounted. The axle is threaded at each end. End
washers are then placed on both ends of the axle. Heavy axle nuts
are then threaded onto each end and tighted to a recommended
torque of 2000-2200 ft/lbs. The axle nuts are locked into place by
bolting a nut lock plate around the nut and to the end washers with
bolts and lock nuts. The disc blades, spacer spools and bearings
have both concave and convex surfaces. Care must be taken to
match convex with concave surfaces during assembly. End washers
are either concave or convex and the appropriate washer should be
placed at each end of the axle.
CAUTION: Gang components are heavy. Two-person
assembly is recommended. Follow Safety Guidelines.
To assemble, install the convex end washer and nut on one end of
the axle. Slide one blade concave side down the axle against the
convex end washer. Next slide a bearing onto the axle, concave end
first, against the disk blade. The axle can now be raised to the
vertical position and it will stand without being held. In the upright
position, the convex end washer should be snug against the
underside of the disk blade. If necessary, tilt the axle and disc blade
and place a spacer (eg. a length of 1” X 4” wood) between the nut
and the floor or ground. This ensures the top threaded end of the
axle will be exposed when the gang is completely stacked and the nut
can be installed.
With the axle in the upright position, the remaining components can
be stacked. Keep all the spacer spools between the bearings with the bearings in the outermost
positions on the axle. While stacking the components, make sure all mating surfaces are free of dirt,
rust, grease, grit or any other material that interferes with the mating surfaces. After the last disc is in
place, drop the concave end washer into place. Apply an anti-seize
compound to the axle threads and install the axle nut. Tighten the nut to
remove as much slack as possible. Lower the entire assembly to the
ground using hoist or forklift and chock both sides of the assembly to
prevent it from rolling. Using the gang wrenches provided with the disc,
tighten both axle nuts as tight as possible. It may be necessary to use a
length of 2” pipe on the wrenches for extra leverage. A sledge hammer
may be used to strike the wrench handle for the final adjustment to fit the
nut lock plates. Install the nut lock plates over the axle nuts and attach to
the end washer with the four bolts and lock nuts provided.
