What is the recommended action if one of the outer belts of a matched set of 3 V-belts becomes badly frayed?

• A. Replace only the frayed belt
• B. Replace the whole set of belts even if the other two belts show no signs of wear
• C. Inspect the other belts for potential issues
• D. Adjust the tension of the remaining belts

Answer: (B)

If one of the outer belts in a matched set of three V-belts becomes badly frayed, the recommended action is to replace the whole set of belts, even if the other two belts show no signs of wear. This approach ensures a balanced performance across all three belts. When belts are used in a matched set, they should ideally have similar wear characteristics, ensuring that they share the load equally. If one belt is frayed, it indicates that it has experienced uneven wear, which could potentially compromise the performance and lifespan of the other belts in the set. Replacing only the frayed belt could lead to imbalances in the system, causing the new belt to wear out more rapidly or even become damaged when paired with older belts that might have subtle differences in wear or tension. This is crucial because mismatched belts can lead to increased vibration, noise, and inefficiency in the machinery. Furthermore, using a new belt with older belts can increase the risk of premature failure, leading to additional maintenance costs and downtime. Therefore, the most prudent course of action is to replace the entire set to maintain optimal performance and reliability.
