A compression spring has a first end and a second end, with the first end being positioned to engage the axially movable sheave. A dual stage spring compression mechanism has a spring retainer that engages the second end of the compression spring. The dual stage spring compression mechanism is connected to the axially fixed sheave. The dual stage spring compression mechanism has a first stage compression device that compresses the compression spring by a first preload amount and a second stage compression device that compresses the compression spring by a second preload amount.2/5 00 cn00 2 / 54
