ADJUSTING THE SLIP CLUTCH
ADJUSTING THE LOWER FLIGHTING AND HANGER BUSHING ASSEMBLY
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 locate in center between flighting center and drive-dog. Retighten the bolts. (Make certain that the flighting
center and drive-dog does 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. After removing them from the tube assembly, place a
shim (between 1/8” - 3/16” thick) where the gearbox output shaft and the spline coupler (welded to lower flighting)
meet. 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
“froze” 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.
IMPORTANT: If the machine has never been used or has not been operated for (1) season, the following
is recommended.
After the first hour of operation, the slip-disc clutch should be checked for overheating. After this first check, the
slip-disc clutch should be checked weekly or anytime there is excessive slippage of the friction discs. The slip-
disc clutch should be checked for moisture, which could cause corrosion on the drive plates. If the grain cart has
been idle for an extended period of time, or in wet weather, check to make sure that the friction lining plates are
not rusted or corroded together. The friction lining plates are 1/8” thick new. They should be replaced after 1/32”
of wear to ensure proper operation.
When the grain cart has been idle for an extended period of time, it is important to check the slip-disc clutch to make
sure that it will slip when an obstacle or load heavier than the torque setting is encountered. Use the following
procedure to make certain that the slip-disc clutch will slip and give the overload protection required.

Loosen nut on springs until the springs can rotate freely, yet remain secure on the bolts.
Place a mark on the outer plates of the slip-disc clutch.
Securely attach the PTO and the grain cart to the tractor and start the tractor.
Engage the PTO for several seconds then quickly disengage it.
Turn the tractor off.
The friction lining plates should have been broken loose or “slipped”. Check the marks placed on the outer
plates of the slip-disc clutch. If the marks are aligned, the friction plates are not working properly.
Adjust the nuts on the springs to set the spring compression height to 1.27”
ADJUSTING THE UPPER FLIGHTING
If the upper and lower flighting still does not separate properly during the folding sequence, a small bevel may
need to be ground out of the inside of the lugs where they meet the drive-dog. Grind approximately 1/8” off of
the corner of the lugs where they touch against the drive-dog.
If the upper and lower flightings do not properly separate during the unfolding sequence, the upper flighting may
need adjusting. Before making adjustment to upper flighting, check to see if the lugs and drive-dog are locking
together (If not, dirt in the restricter or a faulty check valve on the hydraulic cylinder that is used to raise the upper
tube may be the cause of the problem. *See instruction for removing dirt from the restricter).
Fold the upper tube assembly into the upright position. Position upper flighting in engaged position with lower
flighting. Locate 4-hole flange bearing on top of the upper 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 a 1/8” space
between the base of the 4-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” space, the upper flighting will need adjusting. To
adjust the upper flighting, loosen the 1 1/4” hex nuts both below and above the 4-hole flange bearing. Move the
1 1/4” hex nuts up or down the threaded shaft on top of the upper flighting until a 1/8” gap is between the base
of the bearing and the upper tube housing. Tighten the 1 1/4” hex nuts.
MAKE SURE THAT ALL POWER IS SHUT OFF BEFORE ADJUSTING THE FLIGHTING ASSEMBLY.
