Claim Text:
1. A turbocharger wheel balance-test jig, comprising: a base defining an axis of rotation, the base having a base clamping face forming at least a portion of a base conical feature that is normal to and rotationally symmetric around the axis of rotation; a clamp mechanism rigidly connected to the base; and an arm extending along the axis of rotation from the clamp mechanism toward the base clamping face, the arm having an arm clamping face forming at least a portion of an arm conical feature that is normal to and rotationally symmetric around the axis of rotation; wherein the base conical feature and the arm conical feature face one another; wherein the clamp mechanism includes an actuator that is actuatable between a locked position and an unlocked position, the locked position rigidly holding the arm with respect to the base, and the unlocked position providing for the arm to be axially moved along the axis of rotation; and wherein the clamp mechanism includes a stop configured to restrict rotation of the arm around the axis of rotation in both the unlocked and the locked positions.
