70% to passWhen one belt of a multiple V-belt drive requires replacing, what will be required?
Aensure the seasoned belts are reinstalled in their proper sequence
Bseason the new belt prior to installation
Creplace the entire belt set
Densure the proper belt dressing is applied
AI Explanation
The correct answer is C) replace the entire belt set. When one belt of a multiple V-belt drive requires replacing, the entire belt set should be replaced. This is because the belts in a V-belt drive are matched and wear together over time. Replacing just one belt would create an imbalance in the drive system, leading to premature wear and potential failure. The entire set of belts should be replaced to ensure even wear and proper power transmission. The other options, while potentially helpful in some situations, are not the correct solution for a single worn belt in a multiple V-belt drive.
