NOTICE
When changing mounting configuration, it may be necessary to reposition breather/oil fill (B), oil
level gauge (H) and drain plug (A). Refer to Figure 3-1, for correct location.
DRIVE INSTALLATION
When selecting a V-belt drive, check to be sure the shaft overhung load limitation is not exceeded. Refer to
FIGURE 2-2
, for overhung load calculations and limitations.
Belt drives must be carefully aligned. Motor and blower pulleys must be parallel to each other and in the same
plane within 1/32 inch. Belt tension should be carefully adjusted to the belt manufacturer’s recommendation using
a belt tension gauge. Check tension frequently during the first day of operation.
Over tightening belts leads to heavy bearing loads and premature failure.
On the direct connected units, alignment and lubrication of couplings to specifications of the coupling
manufacturer is 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.
