Belt drives must be carefully aligned. Motor and blower pulleys must be parallel to each other and in the

same plane within 1/16 inch. Belt tension should be carefully adjusted and belts tightened only enough to

prevent slippage and per the belt manufacturer’s recommendations.

NOTICE

The sheave should be positioned as close as possible to the drive cover. This will reduce the

overhung load and extend the bearing life.

On direct connected units, alignment and lubrication of the couplings to specifications of the coupling

manufacturer are very important. When mounted drives are supplied from the factory, proper alignment

has been established before shipment. However, during shipping, handling and installation, it is likely

that the alignment has been disturbed and final adjustment must be made before startup.
