Top drive inadequately
lubricated.
Fill to appropriate level with grease. Top
drive is not designed to be filled with oil.
Bent flighting sections.
Support auger and remove all flighting
sections. Check for straightness of flight
stubs by rolling across flat concrete
section. Straighten stub or replace as
necessary. Take care not to bend flighting
when reinstalling.
Obstruction in auger tube.
Visually inspect for cloth or trash wrapped
around flighting, or buildup of gum from
oily crops such as flax or canola.
Premature wear on
auger tubes.
Auger being run at low
capacity or empty for
extended period of time.
Frequently occurs on farms using grain
wagons. Auger should not be left
unattended when filling bins. Depending
on application, a belt conveyor may be
more appropriate.
Bent flighting.
Flighting allowed to wear
beyond normal point of
replacement.
When flighting becomes razor thin at
intake, replacement is critical. Since flight
material is double thickness at welded lap
joints, high spots on flight occur and can
accelerate spot tube wear.
The flighting does not
turn.

obstructed.
