If a fan belt is adjusted too tightly, what could this result in?

• A. A generator bearing being worn excessively
• B. A decrease in engine power
• C. An increase in fuel consumption
• D. Overheating of the engine

Answer: (A)

When a fan belt is adjusted too tightly, it can lead to excessive wear on the generator bearing. This occurs because the increased tension on the belt puts more load on the bearings of the driven components, such as the generator. As the generator operates under this additional stress, the bearings are subjected to greater friction and heat, which can ultimately lead to premature failure or damage. In contrast, excessive tightness in the fan belt may also potentially affect other parts, such as causing misalignment or undue strain on the components it drives. However, the primary and most immediate consequence of a belt being too tight directly affects the bearings, leading to their excessive wear.
