10.3.8 Metering Auger Care
It is important to empty the metering augers of
any residual material at the end of the season.
If material is allowed to adhere to the augers
metering accuracy can be adversely affected.
1.
Remove the metering auger flighting from the
housing. Refer to
Section 10.3.8.1 - Metering
Auger Removal
.
2.
Ensure the flighting and housing are free from
buildup (i.e.: fertilizer and seed treatments). If
there is buildup in the liner or orifice, they can
be removed from the auger housing, refer to
Section 10.3.8.2 - Liner & Orifice Removal
.
a.
To clean off any residual material, soak the
auger flighting, liner, or orifice in water
until the buildup has softened and can be
removed.
3. Check auger diameter. If the auger diameter
is less than the minimum specified below, the
auger should be replaced.
4.
Inspect the liner and orifice. If their inside
diameter is more than the maximum inside
diameter specified below or if there are gouges
greater than 1/16” they should be replaced.
5. Inspect the bearings and change any that are
rough.
6. Reinstall the metering augers.
Important
This maintenance should be completed
Seasonally or after material has been left in the
auger for any period of time.
Note
A characteristic of UHMW Metering augers is the
development of flare at the outer edges due to
friction with the product. Note that this has no
significant effect on the auger's output.
