Conveyor Tension Adjustment
Adjustment of conveyor tension is made by tightening or loosening the conveyor tension
adjustment screws. There is a tension adjustment screw on each side of the conveyor
at the right and left ends of the idler shaft. Jam nuts secure the tension adjustment.
Ideally the conveyor shaft should be adjusted so that when correct tension is achieved,
the shaft is near the center of the adjustment slot. Before beginning adjustment,
measure these distances to position the conveyor shaft near the center of the
adjustment slot when proper tension is achieved.
Note: It is necessary to run the conveyor to verify that it is tracking
correctly and not pulling to either side and wearing against
the side frame. Make small adjustments, one at a time on
each side, until proper belt tension is achieved and belt is
tracking properly.
1. Loosen the jam nuts on the adjustment screws away from the conveyor shaft.
2. Use a wrench on the screw head to adjust tension.
•
Turn the adjustment screw counterclockwise to loosen tension.
•
Turn the adjustment screw clockwise to increase tension.
3. Ensure tracking of belt is centered between frames so the belt does not wear on
either side frame. The belt will pull to the side where tension is tighter.
4. When the conveyor tension is correctly adjusted, re-tighten the jam nuts against
the drive shaft to lock-in tension setting.
