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.

Direct Drive Motor Replacement
Procedure For Direct Drive Models:
1) Unplug power to the Conveyor.
2) Remove the Motor Cover.
3) Unplug the Motor Cable from the Motor.
4) Remove the four 8-32 Screws that secure the Motor to the Motor Bracket.
5) Remove the Motor. The Motor separates from the Conveyor at the Coupling.
6) Loosen the setscrew and remove the part of the Coupling still attached to
the Motor shaft. Also, keep the plastic segment (center part of Coupling) with
it if it came off too.
7) Slide the part of the Coupling from Step 6, above, onto the new Motor shaft.
Line up the setscrew with the flat on the Motor shaft. Turn the setscrew down
until it just contacts the flat and then slide the Coupling part until it is .025”
away from the end face of the flat (use a feeler guage). Tighten it here. This
sets the Coupling to the factory position on the Motor Shaft.
8) Align the Coupling parts by rotating either the Motor or the Conveyor. Install
the new Motor with the four 8-32 Screws.
9) Plug the Motor Cable into the Motor.
10) Reattach the Motor Cover.
11) Hand power the Conveyor (See Page 8).
12) Turn on the Conveyor.
