Abstract
A fuel injector including an injection control device valve spring preload adjustment device is disclosed. The fuel injector includes a transverse access passage extending at an acute angle to a longitudinal axis of the fuel injector. The preload adjustment device includes at least one transverse slot that creates a cantilevered thread portion. The cantilevered thread portion is deformed at a deformation angle to a plane perpendicular to the longitudinal axis to form a locking feature.
