- Designed for heavy duty diesel engine accessory drive applications
- Handles the higher torque and power pulses exerted by diesel engines
- Ensures proper belt tensioning
- Heavy duty cast aluminum body and pulley arms for exceptional durability and strength
- Rugged pulleys with dual permanently lubricated bearings for lasting service life
Accessory drive belts wind their way around such components as the power steering pump, water pump, air conditioning compressor, and alternator propelling them when the engine is running. Heavy duty diesel engine accessory drive applications require highly durable belts that are developed to handle high torque and power pulses exerted by today's demanding diesel engines. When you replace your worn belt, it's also recommended that its tensioners and idler pulleys be replaced along with it.
This product features multiple patented components engineered to handle the higher torque and power pulses exerted by today’s diesel engines. Built with heavy duty cast aluminum body and pulley arms along with rugged pulleys with dual permanently lubricated bearings, this tensioner assembly by Dayco provides exceptional durability and strength as well as long-lasting service life. This makes it perfect for use in heavy duty diesel engine accessory drive applications. Moreover, many of Dayco Gold Label heavy duty tensioners have a highly damped design that includes a wave spring and a metal ring with a bonded polymeric surface to act as a radial shock absorber for the tensioner arm while reducing contamination.
