Question 74Refrigeration/AC - 1st Asst/Chief70% to pass
When one belt of a multiple V-belt drive requires replacing, what will be required?
AI Explanation
The correct answer is C) replace the entire belt set.
When one belt in a multiple V-belt drive requires replacing, the entire set of belts should be replaced. This is because the belts are designed to work together as a system, and replacing just one belt can cause an imbalance in the drive and lead to premature wear or failure of the other belts. The new belts need to be matched to ensure consistent tension and load distribution across the entire drive system.
The other options are incorrect because: A) seasoning a new belt is unnecessary, B) belt dressing is not required when replacing the entire set, and D) the proper sequence does not need to be maintained when replacing the full set of belts.
