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.
CAUTION
Excessive belt tension can damage the equipment. Tension the belts as shown
in Figure 7-2, Page 37.
REPLACING THE COMPRESSOR BELTS
1.
Disconnect, lockout and tagout the power supply to the starter.
2.
Remove the belt guards.
3.
Using adjusting screws, jack the motor base up to loosen the belt tension. Remove the belts.
4.
Install new belts, tighten belts using the adjust screws. Check for correct belt tension.
5.
Check sheave alignment. (See “SHEAVE ALIGNMENT”, Page 36.
6.
Assemble the guards.
CAUTION
Interference between the fan and the orifice can damage equipment. Be certain
the orifice has even clearance around the fan before starting the unit.
