Abstract
A turbocharger assembly is disclosed with a connected lever. An actuator may be spaced away from the lever. An arm may extend from the actuator and may be connected to the lever by a preloaded joint. The joint may include a pin fixed to the lever or the arm. An opening may be provided in the lever or the arm to which the pin is not fixed. The pin may have a shaped section that matches the shape of the opening to provide selected degrees of freedom. A spring element may be engaged in the groove and may apply a force to the pin compensating for wear between the pin and the mating surface by pulling the pin into the opening under the force.
