Abstract
A method for adjusting the valve stroke or a closing duration of a solenoid valve for actuating a fuel injector includes first screwing a magnet adapter nut in a first screwing course on an injector body until a target stroke for the valve stroke is attained at a first torque. Upon attainment of the target stroke at the first torque, a further rotation takes place, at a differential torque. Next, the magnet adapter nut is unscrewed until a torque is reliably undershot. After that, rescrewing of the magnet adapter nut takes place in a second screwing course until the target stroke is attained at a second torque.
