Off-centered pulleys generate the noise and vibration, and accelerate the process of wearing the belt and

pulley to cause the damage to the belt. Align the center of the pulley during the replacement of a belt and

the adjustment of the belt tension. With the compressor fixed, loose the anchor bolt on the motor, and

place an iron rule between the pulleys as shown in the following fig. Gradually tighten the anchor bolt on

the motor and check the center is aligned between the pulleys. Completely tighten the bolt, recheck the

alignment, and then rotate the pulley to check if the belt moves smoothly.
