Dayco 'No Slack' Idler/Tensioner Pulleys
Designed to maintain constant tension on serpentine belt drives Serpentine belt drives consist of a single belt that powers most, if not all, of the engine's accessories.To maintain the proper tension throughout the drive, an automatic, spring-loaded tensioner is incorporated into the drive system geometry. Dayco's Automatic Belt Tensioner 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 steel locator pin (where the application demands). A heavy-duty cast aluminum spring case resists cracking and fatigue. The heavy-duty cast aluminum arm offers additional strength and less distortion . An aluminum retainer ring locks the spring case and arm together, and seals against corrosion.A steel pivot tube (where the application demands) provides additional strength for critical torque requirements. 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, Dayco Automatic Tensioners come with either a glass-filled polymer (plastic) or steel pulley, that features a dust cover to protect against contaminants.
