A. Begin by removing the Unload Tube Assembly
End Cap if you have not done so already.
10. ASSEMBLING AND INSTALLING THE UNLOAD FLIGHT
D. Attach the Discharge Unload Flight to the
Connecting Shaft using two (2) ½” x 3-½” Grade 8
bolts and Stover nuts.
B. Locate the Inner Unload Flight. One end of this
Flight should have a Square bushing; the other
end has a Round bushing with two (2) cross-
drilled holes. Attach the 1-½” OD x 9-½”
Connecting Shaft to the Inner Unload Flight using
two (2) ½” x 3-½” Grade 8 Hex bolts and Stover
nuts.
C. Align the Outer Unload Flight to the Inner Unload
Flight, making sure that the Dura-Edge on both
Flights are as continuous as possible, the angle
between both faces being less than 90°
wherever possible, but not greater than 180° and
without overlapping.
Overlapping the Flights, or having an angle between the ribbon faces be
greater than 180°, will result in reduced unload cap acity.
On 36’ and 42’ diameter bins, the Unload Flight is one piece. Skip Steps B – D.
