1999 Mack RB Belts and Hoses

This Heavy Duty Truck and Bus tensioner is designed, engineered and manufactured by Litens – the world’s largest supplier of original equipment (O.E.) belt tensioners in the world. The Litens replacement part meets all form, fit, and performance characteristics of the original equipment part (with the exception of not having the car manufacturer’s logo or part number applied to the part). This part is manufactured to meet or exceed the performance and life specifications of the O.E. part. The part features a premium chrome-silicon steel spring, internal damping, a “lift-lug” feature for ease of installation, Tandem 6303 ball bearings, a molded locator pin for precise installation, and a forged steel pulley. Specifically designed for a wide variety of Mack Trucks and Buses with E6/E7 (12.0L) engines. Litens is the world’s largest supplier of original equipment (O.E.) power transmission products. At Litens, we design systems that are more efficient, resulting in tangible fuel economy/emissions benefits. Litens holds over 2000 patents and continues to respond to the ever-changing automotive industry by investing heavily in new technology, facilities, and people. 90% of our line is made of products coming from the OE manufacturer, which makes the Litens Tensioning Products portfolio the purest OE tensioning line in the North American aftermarket.

Product Features:

• Manufactured by the world’s largest Original Equipment supplier of accessory drive tensioners and pulleys.
• Internal “round spring” technology to provide constant belt tension and alignment throughout its service life. The internal damping design provides quiet, smooth, system performance.
• Installation instructions included.
• Heavy Duty Electro-deposited coated (e-coat) Steel Pulley for superior corrosion resistance.
• Professional Mechanics will change this tensioner in approx. 1/2 hour
• Accessory drive belts and tensioners are manufactured with similar design life targets. Since belt removal is required to change the tensioner, replacing both will extend the system service life and lower labor costs versus individual replacement.

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
