Motor Pulley Gauging
Important: This procedure is for Belt Drive models.
Many problems can occur if the Motor Pulley and the Drive Side Pulley are not properly
aligned. Problems created by running a Conveyor with a poorly aligned Drive Belt include:
1) Worn Drive Components
2) Debris accumulation from pulley wear.
3) Drive Belt breakage
4) Belt noise
5) High current draws
The importance of proper Drive Belt alignment cannot be overstated. Therefore, Motor
Pulleys should be gauged every time that the Drive Belt is removed or whenever it can easily
be gauged as part of another maintenance procedure.
Please Note: Make sure that the proper Gauge is being used.
Procedure:
1) Unplug power to the Conveyor.
2) Remove the Drive Belt (See Page 13).
3) Slide the Gauge (*Not Provided) between the Motor Pulley and the Motor
Mount. If the gauge* slides in and fits snugly, the Motor Pulley is positioned
correctly, skip to procedure number 7. If not, continue to procedure number 4.
4) Loosen the set screw(s) on the Motor Pulley.
5) Slide the Gauge* between the Motor Pulley and the Motor Mount.
6) With the Motor tightly held to the Motor Mount, press the Motor Pulley and
Gauge* to the Motor Mount, tighten the set screw(s).
7) Slide the Gauge* out.
8) Attach the Drive Belt (See Page 13).
9) Visually confirm that the Drive Belt is aligned vertically on the Motor Pulley and
Drive Side Pulley.

Drive Belt Removal
Procedure:
1) Unplug Power to the Conveyor
2) Remove the Collar Clamp, Drive Side Cover, and Drive Side Product Guide.
3) Remove the Motor Cover.
4) Loosen the four upper Motor mounting screws.
5) Slide the Motor up and remove the Drive Belt from the Motor Pulley.
6) Pull the Drive Side Pulley away from the Rail and off of the Drive Post.
7) Lift the Drive Belt off of the Drive Side Pulley.
Drive Belt Attachment
Procedure:
1) Place the Drive Belt on the Drive Side Pulley.
2) Put the Timing Belt onto the teeth of the Drive Side Pulley.
3) Slide the Drive Side Pulley onto the Drive Post. Turn the Drive Side Pulley with
your fingers to ensure that the Timing Belt is properly seated.
4) Slide the Motor up and put the Drive Belt around the Motor Pulley. Spin the
Pulley until the Belt is properly seated.
5) Gauge the Motor Pulley (See Page 12).
6) To set the Drive Belt tension, see Page 14.
7) Tighten securely using a 9/64”hex wrench and an 11/32” combination wrench.
8) Visually check the Drive Belt alignment.
9) Reassemble the Collar Clamp (See Page 11).
10) Replace the Product Guide.
11) Hand power the Conveyor (See Page 8).
12) Reattach the Cover.
13) Hand power the Conveyor.
14) Reattach the Motor Cover.
15) Turn on the Conveyor.

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.
