  • Patent number: 4845818
    Abstract: A specially designed holding device for holding a fuel pump push rod in place during the installation of a fuel pump on an internal combustion engine is threaded into an existing threaded bore which intersects the passage containing the push rod. The holding device comprises an elongated threaded member of relatively soft metallic material compared to that of the block, e.g. aluminum, and having safety means for preventing damage to the push rod comprising an undersized forward inner thread portion, i.e. the first 21/2 to 3 threads, which will strip more readily than the threads of the engine block in the bore when over tightened. Alternatively, the safety means comprises a relatively soft metallic inner end portion or tip on the holding device.

  • Patent number: 4720900
    Abstract: An existing bolt on certain V-8 engines near and laterally inwardly of the engine fuel pump is aligned with the fuel pump push rod driven by the engine cam shaft. When installing a new fuel pump, the existing bolt is removed and a push rod holding screw of sufficient length to engage and hold the fuel pump push rod is temporarily installed in the threaded opening previously accommodating the removed bolt. The holding screw is turned manually until it engages the fuel pump push rod to hold the push rod elevated while the fuel pump is being installed. The procedure assures that the push rod will be in proper operative engagement with the fuel pump arm when the fuel pump installation is completed, following which the push rod holding screw is removed and the bolt is reinstalled in the threaded opening of the engine block. Haphazard and unreliable methods of holding the push rod up during the fuel pump installation with table knives, screwdrivers and a variety of crude tools are fully avoided.
