Dayco’s automatic belt tensioner maintains proper belt tension throughout the belt drive by incorporating an automatic, spring-loaded tensioner into the drive system geometry. It features a patented “flat spring” design that’s engineered to provide less operating range variations in tension. This reduces the risk of premature accessory bearing failure due to high tension when a new belt is installed. It also lessens the risk of belt squeal and slippage, or poor accessory performance caused by low tension after the belt begins to stretch and wear. A Teflon strip wound within the spring resists abrasion. The flat spring itself is coated to resist rust.

 

Other superior design features include:

  • A heavy-duty cast aluminium spring case resists cracking and fatigue.
  • A heavy-duty cast aluminium arm offers additional strength and less distortion.
  • An aluminium retainer ring locks the spring case and arm together, and seals against corrosion.
  • A thermoplastic rubber “spring slot plug” keeps out harmful contaminants.
  • The lubricated nylon “pivot tube bushing” and “spring bushing” promote quieter performance.
  • A rubber “O” ring seals against dust and grime.
  • The zinc coated mounting bolt resists rust, and is concentric for a more even degree of constant tension.


In order to meet OEM performance standards, this Dayco automatic tensioner comes with a steel pulley that features a dust cover to protect against contaminants.
