  • Reduced shank external flow passage bolt with integral pilot
    Patent number: 6503038
    Abstract: A specially designed bolt fastens together two parts of an engine and in particular can fasten together two components of a rocker arm assembly. The bolt is in a bore passing through the two components. The bolt has a full-diameter pilot that closely fits with the bore at a location where the components mate, and thereby locates the components relative to each other. On opposing axial sides of the pilot are reduced-diameter shank portions of the bolt, which form cylindrical gaps with the bore. The pilot has groove communicating the cylindrical gaps, whereby the gaps and grooves form an oil flow path along the bolt. A duct in each component communicates with a respective one of the cylindrical gaps, so that oil flows through one component, along the bolt and then into the other component.
