What problem can uneven belt wear, belt snags, and lacing separation indicate?

• A. Excessive belt tension
• B. Worn rollers
• C. Misaligned motor
• D. Belt slippage

Answer: (A)

When a belt is over-tensioned, all of the forces are amplified along its length and at its contacts with pulleys and guides. That extra load makes the belt wear unevenly, often eating into one edge or particular zones rather than across the full width. The higher tension also stresses the belt’s lacing or joints, so you can see lacing separating from the belt fabric over time. The belt becomes less forgiving of small misalignments or obstacles, so it tends to snag on guides, corners, or frame features rather than running smoothly.

If tension is set correctly to the manufacturer’s specification, the belt should wear more evenly, track reliably, and lacing should remain intact. Other issues tend to produce different symptoms: slipping usually indicates too little tension or worn drive surfaces; worn rollers or misaligned motors cause tracking or edge wear but not the characteristic lacing separation seen with excessive tension.
