Drive Belt Tensioning
1) Check the tension on the Belt. There should be about 1/8” of flex. See
diagram. If the tension is not properly set, proceed.
2) Unplug power to the Conveyor.
3) Loosen the four motor mounting screws.
4) Let the Motor settle to the bottom.
5) Hold the Motor square to the Motor Mount with one hand; tighten the screws
until snug with the other hand.
6) Check the tension on the Belt. There should be about 1/8” of flex.
7) Repeat procedure, if necessary, until proper tension is achieved.
8) Fully tighten the screws using an 11/32” wrench to hold the nuts while
tightening the screws.
9) Hand power the Conveyor.
10) Turn on the Conveyor.
Important: Operating a conveyor that has a Drive belt that is too tight will greatly reduce the
life of the Drive Belt. Operating a conveyor that has a Drive Belt that is too loose will cause
the Drive Belt to skip which will also greatly reduce the life of the Drive Belt and generate
noise.
