Abstract
An apparatus is provided having two mating components. The mating components include an engine and an engine front cover. A fastening boss is formed on at least one of the two mating components and configured to receive a threaded fastener to join the two mating components. A compression boss extends from a first of the two mating components to contact a second of the two mating components. The compression boss is dimensioned relative to the fastening boss to create compressive loading in the compression boss when the threaded fastener is tightened to join the mating components.
Claims15
An apparatus comprising:
- two mating components including a front cover and an engine block defining a receiving surface disposed at a depth below a primary surface of the engine block and a front cover;
- a fastening boss formed on at least one of the two mating components and configured to receive a threaded fastener to join the two mating components;
- and
- a compression boss defining a receiving aperture extending partially therein at an upper portion thereof and the compression boss extending from the front cover to contact the receiving surface and sized relative to the fastening boss to create compressive loading in the compression boss when the fastener is tightened to join the two mating components.
An apparatus comprising:
- a front cover including a compression boss without a fastener element and a fastening boss;
- and
- an engine defining a receiving surface at a depth below a primary engine surface which does not facilitate mechanical fastening and including a threaded aperture to receive a fastener through the fastening boss to join the front cover and engine, the compression boss contacting the receiving surface when the front cover and engine are joined, the compression boss dimensioned to create compressive loading therein when the fastener is tightened, and the compression boss defining a receiving aperture extending partially therein at an upper portion of the compression boss to receive an engine accessory.
A method comprising:
- securing a fastener through a fastening boss formed on at least one of two mating components including a front cover and an engine to join the components and positioning a compression boss defining a receiving aperture extending partially therein at an upper portion and the compression boss formed on one of the components into compressive contact with a receiving surface at a depth below a primary surface of the other component.
