PNEG-1429 Horizontal Drive Units 13
Inserting Discharge Flight
1. Once the discharge tube has been bolted to the unload tube, slide the discharge flight into the tube
and align the connecting shaft holes with the holes on the unload flight. (See Figure 4B.)
2. Align the drive unit discharge flight to the unload flight, making sure that the Dura-Edge® on both
are as continuous as possible, the angle between both faces being less than 90° wherever
possible, but not greater than 180°, and without overlapping.
NOTE: Overlapping the flights, or having an angle between the ribbon faces be greater than 180°,
will result in reduced unload capacity.
3. With holes aligned, secure with grade 8 bolts and stover nuts.
