5.13. Removing the Underfloor Auger Flighting
In certain circumstances (such as general maintenance or troubleshooting), it may be required to remove the
underfloor auger flighting
To Remove the Flighting:
1. Shut down and lock out power to the powersweep system.
2. Release the belt tensioner from the motor plate to disengage the belts. Remove the belts and pulley.
3. Remove the motor plate with attached motor from the head drive unit by releasing the lock from the mount-
ing pin and then lifting the motor plate with motor off the drive unit.
4. Release the 8 bolts that attach the head unit to the underfloor unit.
5. Release the 2 bolts that attach the drive shaft to the underfloor auger.
6. Pull out the auger flighting from the underfloor unit.
To Reinstall the Flighting:
1. Push the flighting back into the underfloor auger
2. Attach the drive shaft from the head unit back onto the underfloor auger with the 2 bolts. Make sure the
insert bearing is loosened on the drive unit for adjustment of the underfloor flighting
3. Push the underfloor auger into the unload unit, rotating the auger slightly to ensure the splined coupler lines
up with the splined shaft on the lower gearbox by the center sump.
4. Attach the head drive unit to the underfloor unit and tighten the 8 bolts
5. Make sure the underfloor flighing is adjusted and set properly onto the lower gearbox spline. To do this,
measure the lower geabox spline shaft from the gearbox plate to the end of the coupler on the underfloor au
-
ger. There should be approximetely 7/8” to 1” of the spline shaft exposed. Adjust if needed.
6. Tighten the insert bearing on the head drive unit. Re-attach the motor plate with motor onto the drive unit.
Install the pulley and belts and adjust the tension as described in Section 5.8.
7. Ensure belt guard is installed.
