Which condition of a belt is NOT acceptable during an inspection?

A cracked condition of a belt is not acceptable during an inspection because it indicates that the belt is damaged and could potentially fail during operation. Cracks in the belt can lead to further deterioration, resulting in loss of tension and eventual breakage, which can compromise vehicle performance and safety. In contrast, a new belt is in optimal condition and suitable for use; a worn belt may still be acceptable as long as it meets the specified tolerances for wear; and an untouched belt, while seemingly appropriate, does not provide information about its actual integrity or performance under stress. Ensuring that belts are in good condition is crucial for the proper functioning of the engine and other systems they drive.
