Replacement is necessary in the event of visible cracks in the rubber element, unusual squeaking or rattling noises from the belt drive or in the event of strong vibration. Experts recommend an inspection at least every 60,000 kilometers.

A simple method is to put a continuous mark on the shock. After starting and a short load change, the marking should continue to be congruent, otherwise there is a defect.

Yes, the V-ribbed belt should be replaced every time the pulley is replaced. An old belt, which may already be slightly elongated, can damage the new pulley at an early stage due to uneven loading.

These pulleys have an integrated rubber element or spring mechanism that absorbs the torsional vibrations of the crankshaft. This protects the bearings of the auxiliary units and ensures smoother engine running.

A breakage of the pulley can lead to the loss of the drive for the servo pump and alternator. In addition, parts of the pulley can get into the timing belt drive, which can result in major engine damage.

New parts are manufactured according to current technical standards and have intact damping properties. Overhauled or repaired components often do not meet the required strength, which is why only the use of new parts is recommended.
