DAYCO AUTOMATIC BELT TENSIONER TO SUIT HOLDEN CAPRICE VS WH ECOTEC L36 L67 SUPERCHARGED 3.8L V6

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.
