During the daily inspection, drive chains are checked for what?

• A. Tension and alignment
• B. Cleanliness and lubrication
• C. Wear
• D. Noise

Answer: (B)

The key idea is that a drive chain depends on being clean and properly lubricated to perform well and last longer. During a daily check, looking for cleanliness and lubrication ensures contaminants don’t damage the chain and that a protective lubricant film is present. Dirt and grit act like abrasives, quickly wearing pins and rollers, while lubrication reduces friction, carries away heat, and resists corrosion. If the chain is dirty or under-lubricated, wear accelerates, links can become stiff or noisy, and the risk of failure rises. Other aspects like tension, alignment, wear, or noise matter, but they’re much more likely to cause problems if the chain isn’t kept clean and well-lubricated.
