Abstract
A clutch is provided that includes a fixed sheave portion, a movable sheave portion, a movable sheave assembly, an idler bearing and a torque drag member. The movable sheave assembly is configured to axially move the movable sheave portion in relation to the fixed sheave portion in response to a change in a rotational speed of the clutch. The idler bearing is rotationally mounted on a central post of the fixed sheave portion. The idler bearing is positioned to engage an inside face of a belt when the fixed sheave portion and the movable sheave portion are located a select distance away from each other. The torque drag member is operationally coupled to exert a select amount of torque drag on the idler bearing.
