Sheave Installation
NOTE: Owners and installers of 7000 bushel per hour Series II Sweeps using 230/460/575 Volt,
60 Hertz power should note that the belt drive for a 7000 bushel per hour sweep uses a special
“Speed Up” style belt and sheave arrangement. The drive sheave is larger than the driven sheave.
In almost all cases the drive sheave is a 7.15" outside diameter (6.8" P.D.) with the driven sheave
a 6.3" outside diameter (6" P.D.)

WARNING
To ensure that the drive is not unexpectedly started, turn OFF and lock out the
power source before proceeding. Failure to observe these precautions could
result in bodily injury.
CAUTION
Wedging forces in the bushing saw slot, such as that exerted by a narrow edged
regular screw driver, may damage or break the bushing. This damage would not
be covered under the GSI warranty.
