BELT TRACKING
With the belts tensioned, "bump" the motor to be sure rotation is correct, the belts are running smoothly and
maintaining their position. Most NBS conveyors do not require belt tracking. However, each conveyor should be
checked at the charge and discharge ends to be sure the belts are floating in a neutral position not crowding the
sides of the UHMW guide tracks. If the belts are out of their grooves or riding hard to one side adjustment can be
made on the driven pulley jackscrew, at the discharge end, or the snubber roller in the end pulley assembly at the
charge end, to realign them.
Reinstall the bottom pan on the end pulley assembly and
access covers on the drive bed, NBS 30 diverter and charge
end pulley.
