Vehicle Repairs. We've Got What It Takes. Belt drives have the task of transmitting and driving the rotary motion of the crankshaft to the engine control system or to the auxiliary units. Belt drive components are therefore required to deliver maximum performance in every vehicle. In order for the belt drive to run optimally, the belt tension specified by the manufacturer must be maintained. febi offers a comprehensive range of tensioner assemblies for auxiliary belts in OE matching quality. Quality by Conviction. The tensioner assembly not only keeps the auxiliary belt tensioned, it also compensates for the elongation of the belt over time. It also absorbs vibrations so they do not have a negative effect on the functioning of the auxiliary belt. The quality of the tensioner assembly must be perfect for these tasks. Tensioner assemblies from febi are therefore intensively tested. Our quality management tests the tensioner assemblies on offer for various requirements and loads, e.g. fitting accuracy, dimensional accuracy, material quality, and tensile strength. Complete Repair Kits. When replacing the auxiliary belt, the surrounding components should also be checked for wear. For all parts to work together perfectly, it is extremely important that they are precise and made of high-quality materials. febi offers complete auxiliary belt kits for certain vehicle types which contain all the individual parts required for professional replacement.
