Common Tensioning Roller Issues and Why Replacement is Necessary. Over time, a tensioning roller can wear down due to constant exposure to engine heat and mechanical stress. Typical problems include:
- Bearing Wear: The internal bearing may deteriorate, causing noise and reducing performance.
- Seized Pulley: Rust or corrosion can lock the pulley, disrupting proper belt tension.
- Cracked or Damaged Pulley: Physical damage can misalign the belt and hinder the roller’s function.
- Replacing a worn tensioning roller is crucial to maintain proper belt operation, prevent squealing noises, and avoid potential damage to other engine components.
