What is an effective method for troubleshooting a drive belt that is squeaking?

Using chalk to remove glaze is an effective method for addressing a squeaking drive belt. Over time, drive belts can develop a smooth, glossy surface known as glaze, which can hinder their ability to grasp pulleys properly, leading to slipping and audible squeaking noises. By applying chalk to the belt, you can enhance friction, allowing for better grip on the pulleys, thereby potentially alleviating the squeaking issue.

This approach is particularly beneficial because it is non-invasive and can be accomplished quickly, making it an ideal first step in troubleshooting. It targets the surface of the belt directly and can yield immediate feedback regarding the effectiveness of the treatment.

In contrast, other methods such as replacing the entire belt may not be necessary if the problem can be resolved through simpler means. Inspecting for wear on pulleys, while a good maintenance practice, might not immediately address the specific issue of squeaking unless wear is conclusively determined to be the root cause. Applying oil to the belt is generally not a recommended solution, as lubricants can actually make the problem worse by further reducing the belt's ability to grip the pulleys.
