Abstract
An internally splined rotary anti-backlash component is adapted to engage an externally splined injection-pump shaft end. Fixing pins extend radially through the component and have wedge-shaped ends which protrude into gaps between the splines of the shaft end. This inhibits backlash between the component and the shaft end for a predetermined sense of rotation of the component relative to itself. The component can be disengaged from the shaft end, turned around back-to-front, and re-engaged, to allow the sense of drive to be reversed.
