• Idler pulley vibrates during use.

• Pulley develops surface damage.

Belt Tracking Problem

Quick Check: Watch the belt path and determine whether it remains centered as it passes over the idler pulley.

Fix Suggestion: Examine the pulley position and belt alignment for signs of shifting or component wear.

Prevention Tip: Keep the drive assembly clean and review pulley alignment during routine maintenance.
