In addition to the drive belt itself, a V-belt that is tensioned too tight will cause excessive wear to what other drive component?

Correct Answer: Option C — motor shaft and compressor main bearings

Excessive V-belt tension creates severe radial loads perpendicular to rotating shafts. This abnormal mechanical stress accelerates friction and fatigue, leading to premature wear and failure of both the prime mover motor shaft bearings and the compressor main bearings.
