or until the friction clutch visibly smokes.
6) Disengage the tractor PTO and shut the tractor off.
7) Disconnect the driveline from the tractor.
8) Tighten the (6) bolts (Item 8) on the O.D. of the clutch pack

Adjusting the Slip Clutch
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 THAT ALL POWER IS SHUT OFF AND THE UPPER AUGER TUBE IS IN THE DOWN POSITION BEFORE
REMOVING THE RESTRICTORS
Remove restrictors from the 90 degree street elbow on the hydraulic cylinder. Remove dirt from the fitting to allow hydraulic
oil to flow through the restrictor. Reattach the restrictor to the street elbow. Use teflon sealant tape or equivalent on the
threads of the restrictor before reattaching.
If the restrictor continues to plug with dirt, replace the restrictor or filter the hydraulic oil in your system.
