Torsional Vibration Dampers

Design and function

A TVD consists essentially of:

A) Flywheel
B) Belt pulley
C) Damping elastomer track
D) Sliding bearing
E) Coupling elastomer track (only in case of TVDi)

Torsional Vibration Dampers

The rotating flywheel stabilizes the belt drive. Vibrations in the crankshaft are absorbed by the elastomer track (C). The inner elastomer track (E) damps the cyclic irregularities in the crankshaft.


Replacement interval:

Torsional vibration dampers (TVD) are subject to aging and wear and therefore have to be regularly checked and replaced. Continental recommends inspecting the TVD every 60,000 km and, if in doubt, changing it every 120,000 km.


  • Store in a dry, dust-free and cool place (ideally 15-25°C)
  • Avoid contact with all liquids (oil, water etc.)


  • Faulty torsional vibration dampers are often the cause of noise or damage in the belt drive (e.g. tensioner)
  • Check the TVD for damage every time the belt is changed
