What is a common symptom of belt misalignment?

A common symptom of belt misalignment is the generation of noise during operation. When a belt is not aligned properly, it can create friction and vibration as it runs against surrounding components or the pulley itself. This misalignment can lead to a rattling, squeaking, or slapping noise, indicating that the belt is not tracking correctly. Identifying noise as a symptom is crucial because it alerts operators to potential issues that could lead to further mechanical problems or failure if not addressed promptly.

The other choices do not align with the symptoms of belt misalignment. Increased cooling is unlikely since misalignment usually leads to additional friction, which can result in excess heat rather than cooling. Consistent operation speed is also not characteristic of misaligned belts, as misalignment often causes variations in speed due to slipping or uneven tension. Improved torque transfer would not occur with misalignment; in fact, it often leads to a loss of efficiency, as the belt may not effectively transmit the power it is designed for. Understanding the implications of belt alignment is essential for maintaining equipment efficiency and longevity.
