6.4.3 V-belt Tension Adjustment
1. Slightly loosen the bolts holding the prime mover onto the base plate (1).
1. Adjust motor position until the V-belt tension is correct (2).
2. Tighten the prime mover mounting bolts.
3. Operate the unit for approximately five minutes. Stop the prime mover, check V-belt tension and
readjust if necessary.
4. After the V-belt tension is correct and the prime mover mounting bolts are tight, check to verify that
both pulleys are aligned. This is necessary to avoid excessive wear on the V-belt and pulleys.
5. Hold a straight edge against the compressor and prime mover pulleys as shown in Figure 6-4. The
straight edge must touch the pulleys at the four points indicated by the arrows. If it does not, adjust
the prime mover position until it does.
