SECTION 7
BELT DRIVE
Proper drive belt tension and alignment are provided at the factory. However, good practice dictates
checking the drive alignment and tension after shipment and before initial start-up.
Sheaves should align straight across the front with a straight edge. The best tension is just enough
tension to keep belts from “squealing” on start-up.
WARNING
The motor is held up to prevent belt damage during shipment. Remove the
shipping hardware to lower the motor to its operating position prior to starting
the package. Loosen locking nut and unthread the long set screw the majority
of the way (this lowers the motor) and tighten the locking nut. Then remove the
screws clamping the vibration isolators on the airend sub-base.
CAUTION
Excessive belt tension can damage the equipment. Tension the belts as shown
on Figure 7-1. See Replacing the Compressor Belts, page 59.
