Abstract

An apparatus is proposed for positionally fixing a drive shaft disposed in a fuel injection pump for internal combustion engines in a predetermined rotary position, in particular one associated with the onset of fuel supply, and for measuring and testing this rotary position. The apparatus is provided with an apparatus into the reception bore of which either a holder element or an electric pulse transducer can be inserted. An element firmly connected with the drive shaft is provided with an angle-indicator marking, which is equipped both as a coupling element for the position-fixing apparatus and as a pulse trigger for the pulse transducer. The apparatus can thus be used both as a locking apparatus for mounting the injection pump on the engine and, with the pulse transducer inserted, as a measurement and testing apparatus.
