While it's important to check for play in the belts, particularly for excessive slack that could affect their performance, the most critical condition to examine involves the integrity of the belts themselves. A vital condition to look for in the belts is whether there are cracks and frays. These defects can significantly compromise the strength and usability of the belts, potentially leading to failure during operation.

Inspecting the belts for cracks and frays ensures that they are not worn or damaged, which is crucial for the safe and efficient operation of the vehicle. Belts with signs of deterioration can snap, leading to mechanical failures. Therefore, focusing on the condition of the belts, including their surface integrity, is essential for a thorough pre-trip inspection.
