ContiTech Kit Ensures That Things Run Smoothly

Torsional vibration dampers (TVD) are essential in modern, fuel-saving engine generations. Belt pulleys perform a key function in the drive system, absorbing vibrations from the crankshaft. As well as conserving the drive belts and assemblies, torsional vibration dampers ensure that the engine runs more quietly, thus contributing to a reduction in noise emissions. For the drive belt, the torsional vibration damper is a particularly important partner, since both components together ensure that things run smoothly. The ContiTech Power Transmission Group, a leading manufacturer and development partner for drive belts, is now offering its V-ribbed belts in a kit with torsional vibration dampers and torsional vibration damper isolators (TVDi).

If the TVD fails, this can have serious consequences for the drive system: the torsional vibrations of the crankshaft are no longer absorbed, thereby damaging both the belt and the driven accessories. "Mechanics should therefore check belt pulleys for cracks, deformation or traces of corrosion each time the belt is replaced," recommends Markus Pirsch, marketing service manager at the ContiTech Power Transmission Group. "Since damage is not always evident, although it very much impairs the proper functioning of the engine nonetheless, replacement is advisable every 120,000 km."

The CONTI-V MULTIRIB® KIT from ContiTech minimizes the work required for installation and maintenance and provides optimal support for automotive mechanics in their day-to-day workshop practice. When replacing a belt, all required components are right at hand and optimally matched. Besides the belt pulley and the belt, the kits also include the required retaining bolts and sealing rings. The screws used are special OE screws which must be replaced when changing the TSD. The TVD kit is also listed in TecDoc, the digital information system which provides comprehensive purchasing data to independent spare parts dealers and workshops.
