In an aspect, an isolator is provided for isolating torsional vibration between a crankshaft of an engine and an endless drive member. The isolator includes a driver drivable by the crankshaft, a pulley that is engageable with an endless drive member, at least one isolation spring that is positioned to transfer forces between the driver and the pulley and to isolate torsional vibrations in the driver and the pulley from one another, and a damping structure configured to frictionally resist relative movement between the driver and the pulley beyond a selected relative threshold angle, and to permit relative movement between the driver and the pulley within the selected relative threshold angle without frictional resistance from the damping structure.
