Maintenance
14. ENCLOSED DRIVE
LUBRICATION
A. The enclosed drive is located at the discharge
end of the auger housing and is shipped without
oil. Oil is to be added to the unit during field
assembly of the auger. Oil will dissipate under
normal operating conditions, therefore the oil
level should be checked regularly. Add 90 EP
(non-foaming) oil until the oil level reaches the
check point.
B. For lubrication in normal operating temperature
between 40º F to 120º F, we recommend the
use of non-foaming, multi purpose gear oil. Use
SAE 90 weight for normal operating tempera-
tures. For temperatures below 40º F, use SAE
80 weight oil. Use a grade of oil commercially
available for automotive differentials. Extra
pressure additives may be of value in severe
applications.
FIG. 30
DO NOT add more oil than recommended.
Additional oil may damage the seals or be forced
out through the vented plug.

15. REDUCTION SWEEP WHEEL
A. Add two ounces of multi purpose gun grease to the
sweep wheel drive enclosure during assembly and
each time the bin has been emptied. Use the grease
zerk on the drive housing.
13. BELT TENSION
A. Check the belt tension on electric drive. To tighten
belts, use the adjusting rod on the motor mount
assembly. DO NOT over tighten belts.
A. LOW CAPACITY
Sweep capacity may vary as the angle of sloping grain
varies. Check the horsepower requirements on pages 34,
to determine correct operating speed and the motor pulley
size recommended for that speed. If a greater or lower
capacity is desired it may be possible to change the
motor pulley which will change the sweep flight speed. Do
not attempt operation at speeds greater than 50 to 100
RPM above standard recommended speed. Do not operate
a sweep that is overfeeding the unloading auger unit. The
slide gate in the center well should be left full open during
sweep operation.
B. SWEEP FLIGHT & BACK SHIELD NOT MOVING
DO NOT STORE SWEEPS IN THE BIN!
Sweeps are NOT designed to remain in a bin during filling,
storage, or bottom (gravity) unloading. A sweep left in a bin
during these operations may be serverly damaged. The
GSI Group, Inc. will not be responsible for such damages.
The following action may reduce damages to a sweep
remaining in a bin: Lifting the sweep off the center pivot,
positioning it parallel to the intermediate wells (along side
of - not on top of) and fully supporting the sweep to the bin
floor. However, even with this procedure, The GSI group,
Inc. will not be responsible for any damges to the sweep.
Check clearance between back shield and the bin floor for
excessive drag. It may be possible to adjust the back
shield up by working the slotted connections between
back shields at bearing brackets.
The grain may have gone out of condition due to moisture
or insect activity and has become hard or caked. Stop the
sweep auger and lockout power before entering the bin to
correct this or any other difficulty. Make sure the grain
hasn’t flowed abnormally or bridged over. See page 30 for
illustrations.
