ABSTRACT:
The invention teaches a method of manufacturing a torsional vibration damper in which a metal hub ring and a metal inertia ring surrounding the hub ring are radially spaced apart by a gap. A spring body of rubber-elastic material is fired into the gap with the aid of a lubricant, the spring body and/or the surfaces of hub and/or inertia ring facing the gap being wetted with a lubricant composed of a water-salt solution prior to insertion of the spring body.
