A gear and a method for combining a first gear with a second gear including the steps of moving the first gear relative to the second gear such that a first tooth of the first gear contacts a second tooth of the second gear, pressing the first tooth of the first gear against the second tooth of the second gear such that a resultant force is not directed to a center of at least one of the first gear or the second gear, wherein a torque is created by the resultant force, and rotating at least one of the first gear or the second gear based on the created torque until first teeth of the first gear mesh with second teeth of the second gear.
