It is provided a method for executing a movement between a hub (22) and a pulley (28) of an isolator (20), wherein the hub (22) defines an axis, the pulley (28) is rotatably mounted to the hub (22) through an isolation spring (24) and a transmission spring (26) connected together via a rotatable intermediate member (25), wherein the isolation spring (24) has a first spring rate and the transition spring (26) has a second spring rate. The method comprising: executing a relative movement in a first rotational direction between the hub (22) and the pulley (24) away from a home position throughout a first range, and executing a relative movement beyond the first range and between the hub (22) and the pulley (24) away from the home position throughout a second range, wherein during the relative movement throughout the first range the effective spring rate of the isolator (20) is the series sum of the first and second spring rates, and wherein during the relative movement throughout the second range the effective spring rate of the isolator (120) is the first spring rate; and executing a relative movement in a second, opposite, rotational direction between the hub (22) and the pulley (24) away from a home position throughout a third range, wherein during the relative movement throughout the third range the effective spring rate of the isolator (120) is the first spring rate.
