2012 Freightliner XB Line Belts and Hoses

For heavy duty diesel engine accessory drive applications, Dayco’s HD automatic belt tensioner is designed to handle higher torque and power pulses. The heavy-duty cast aluminum body and pulley arms translate into extra strength and durability and the patented flat spring design prevents fluctuations to the tensioner body as its footprint doesn’t change when it’s under tension. This reduces the risk of belt noise and also helps avoid separation of the housing a key failure seen from competitive products. Dayco automatic belt tensioner H.D. also includes rugged pulleys with dual lifetime lubricated bearings to deliver long lasting, dependable service. Feature highly damped designs using a wave spring and a metal ring with a bonded polymeric surface that acts as a radial shock absorber for the tensioner arm while reducing contamination.

Product Features:

• Designed to prevent fluctuations to the tensioner body for longer service life.
• Reduces the risk of noise and helps avoid housing separation
• Includes pulleys with lubricated bearings for longer lasting performance
• Heavy-duty cast aluminum body and pulley arms translate into extra strength and durability
