Chain Adjustment
Standard Conveyor
Chain tension can be adjusted by moving the sprocket near the drive motor. Moving closer
to the motor will increase the tension. Moving away will the loosen the tension.
33BFigure 36: Adjusting Chain Tension
Chain tension should have slack at room temperature to allow the conveyor to expand
when it is hot and in use. The chain should sag to the bottom of conveyor extrusion. Proper
tension of the chain is shown below at room temperature.

Pin Conveyor
The pin conveyor has an adjustment screw and tensioner. To increase the tension, turn the
adjustment screw clockwise. To loosen, turn counterclockwise. After adjusting, gently pull
on the chain and release to make sure chain slack is distributed.
