Question 103Refrigeration & AC - QMED

The correct answer is C) motor shaft and compressor main bearings. When a V-belt is tensioned too tightly, it can cause excessive wear and stress on the motor shaft and the main bearings of the compressor. This is because the excessive tension places additional loads on these components, leading to premature wear and potential failure. The other answer choices are incorrect because they do not directly address the components that are affected by excessive V-belt tension. The compressor drive pulley (A) and the prime mover drive pulley (B) may also experience wear, but the primary issue is with the motor shaft and compressor bearings. The shaft of the prime mover (D) is not the component that is directly affected by the tight V-belt tension.
