Conveyor Belt Adjustments Instructions - JackRabbit 30 Manual

CONVEYOR BELT ADJUSTMENTS INSTRUCTIONS

The tension of the belts should be tight enough to prevent slipping when under maximum
load. Belt alignment and tension are maintained by adjusting bolts that slide the pulley
shaft bearings forward and reverse. All adjustments should be made in small increments
with the belt run 1 – 2 minutes between adjustments.
1. Change alignment of the belt: To loosen bearing hold-down bolts. Turn the
adjustment bolt to tighten the belt on the side where the belt is too close or rubbing. Re-
tighten bearing hold-down bolts.
A. Run belt at low speed for 1 – 2 minutes allowing belt to center on pulley.
Re-adjust if necessary.
B. Run belt at fast speed for 2 – 3 minutes while checking alignment.
2. Increase belt tension: To loosen bearing hold-down bolts on idler pulley shaft. Turn
adjustment bolts on each side of the belt an equal amount increasing belt tension.
Re-tighten bearing hold-down bolts.
A. Run belt at low- speed checking for correct tension and alignment. Re-adjust
if necessary.
B. Run belt at fast speed for 2 – 3 minutes while checking tension and alignment.
3.. WoodChuck roller chain is tightened in the same manner as the conveyor belts.
