Abstract

A crankshaft damper includes a hub and a rim. The rim has an outer diameter greater than an outer diameter of the hub. A plurality of spokes connects the rim to the hub. An axial inner surface is formed on the rim and projects forwardly of the spokes. A damper support includes a band and a collar. The band is retained to the axial inner surface of the rim and the collar projects radially outwardly beyond the outer diameter of the rim. An elastomeric member is mounted on the collar and faces the rim. A damper is mounted on the elastomeric member and faces the rim. The elastomeric member and damper are positioned radially beyond the rim to dampen torsional and axial vibrations.
