3. Installation
Your Grain Saver™ Power Sweep System is completely assembled and is ready for in-
stallation in your new concrete foundation, or in your new existing conventional drying,
natural air drying or other style aeration / drying system.
To install Power Sweep System in a concrete foundation:
A. The Splined Gearbox Sweep output shaft is to be the center of the concrete foundation.
B. Set the concrete forms, “stake” the tube in place using the leveling brackets provided on
the Center Hopper to prevent “slip” and “float”.
C. Check control rod sleeves to be certain that they were not bent in shipping or handling.
This could cause difficulty in opening the wells. Straighten if necessary with a pry bar.
D. The discharge end of the tube must be installed at least 1” lower than the intake end to
prevent water build-up in the tube.
E. Pour the concrete foundations to the bin manufacturer’s specifications and let “cure”.
F. Install the sweep assembly with the one bolt “keeper” over the splined shaft.
G. Adjust the sweep backboard to the length by loosening the 4 bolts and rotating the wheel
so the sweep telescopes in or out to the desired location. Tighten the bolts. Sweep should
also be adjusted on both the center and wheel end to ensure proper movement and opera-
tion. Make sure the sweep is not touching the bin floor at any point around the bin.
H. Install Powerhead drive by inserting powerhead drive screw into unload screw and fasten
them with the 2 provided bolts and tighten them. Then tighten the flange clamps on pow
-
erhead drive to flange on unload tube or u-trough. Adjust the unload screw on the spline of
the center gearbox by loosening the insert bearing on the powerhead and sliding the unload
screw and connected powerhead screw in or out so it is connected securely on the spline of
the center gearbox. When properly set, There should be approximitely 7/8” to 1” of spline
showing from the gearbox plate to the unload screw spine.
I. Install sweep safety stop on the inside of the bin wall right behind where the sweep will be
parked when filling the bin, the sweep should be parked right over the sumps.
