Adjusting the Lower Flighting and Hanger Bushing Assembly
WARNING
MAKE SURE THAT ALL POWER IS SHUT OFF BEFORE ADJUSTING THE FLIGHTING ASSEMBLY.
If the drive-dog and hanger assembly are becoming excessively hot during unloading, the lower flighting and/or hanger may
need adjusting. The hanger bushing assembly has elongated holes where it attaches to the outer tube assembly. Loosen
the two 3/8” bolts on the hanger bushing assembly. Adjust the hanger either up or down and vertically center it between the
flighting and drive dog. Re-tighten the bolts. Make certain that the flighting center and drive-dogs do not rub the hanger
bushing assembly, causing them to become hot.
If the hanger can no longer be adjusted by moving it up or down on the elongated holes, both the hanger bushing assembly
and the lower flighting will have to be removed. See instructions on pg. 36 for flighting removal. After removing them from
the tube assembly, place a shim [between 1/8” (0,32cm) to 3/16” (0,48cm) thick] where the gearbox and the spline coupler
(welded to the lower flighting). Replace the lower flighting and reattach the hanger to the tube assembly. Readjust the
hanger assembly. NOTE: The bottom of the lower flighting is not attached to the gearbox with any bolts or set screws
but may be ‘frozen’ fast. Be careful when removing the lower flighting from the gearbox. For easier removal of the lower
flighting, keep the gearbox at the bottom intact, remove the 2 3/8” bolts from the hanger bushing assembly and pull the
lower flighting off of the gearbox.
After adjusting the lower flighting, move the upper auger to the unload position and check the upper flighting for readjustment.
WARNING
MAKE SURE ALL POWER IS SHUT OFF BEFORE ADJUSTING THE FLIGHTING ASSEMBLY
If the upper and lower augers to do not properly separate during the unfolding sequence, the upper flighting may need
adjusting. Before making adjustment to the upper flighting, check to see if the lugs and drive dogs on the auger assemblies
are locking together. If they are not locked together, check to see if dirt is in the restrictor or if a faulty check valve on the
hydraulic cylinder used to raise and lower the upper auger assembly may be causing the problem. If dirt is in the restrictor,
see “Removing Dirt From Restrictors On Hydraulic Cylinders” below.
Fold the upper tube assembly into the upright position. Position the upper flighting in the engaged position with the lower
flighting. Locate the four-hole flange bearing on the top of the upper auger tube housing. With the upper flighting in the
engaged position, check the spacing between the upper bearing and the upper tube housing. There must be an 1/8”
(0,32cm) space between the base of the four-hole flange bearing and the upper tube housing. If there is NOT a space
between the bearing and the upper tube housing, or if there is more than 1/8” (0,32cm) space, the upper flighting will need
to be adjusted. To adjust the upper flighting, loosen the 1 1/4” hex nuts both above and below the four-hole flange bearing.
Move the 1 1/4” hex nuts up or down the threaded shaft on the top of the auger flighting shaft until the bearing moves to
approximately 1/8” (0,32cm) above the base of the upper tube housing. When the four-hole flange bearing is properly
located, tighten both 1 1/4” hex nuts together to secure the bearing position.
If the upper and lower flighting still does not separate properly during the folding sequence, a small bevel may need to be
removed from the inside of the lugs where they engage the drive dogs on the auger assemblies. Grind approximately 1/8”
(0,32cm) from the corner of the lugs where they touch against the drive dogs.
