20140165396 | SELF-CENTERING SEAL - A self-centering seal for a counterbore with an inner passageway and a counterbore diameter defining a recessed area is described. The self-centering seal includes an annular shape including an aperture defined by an inner diameter matched to the diameter of the inner passageway, a circular outer edge having an outer diameter less than the counterbore diameter, a sealing surface at least partially disposed between the inner diameter and the circular outer edge, and a plurality of centering tabs projecting form the outer edge. The self-centering seal may, for example, be used in engine manufacture in conjunction with counterbores and inserts around fluid passages. | 06-19-2014 |
20140165955 | METHOD OF MANUFACTURING AN ENGINE BLOCK - A method for manufacturing an engine block includes removing material from the top deck of the engine block surrounding a first opening to create a first recessed area, placing a first seal within the first recessed area, positioning a first insert within the first recessed area and against the first seal. The method may also include removing material from the top deck of the engine block surrounding a second opening to create a second recessed area that at least partially overlaps the first recessed area, placing a second seal in the second recessed area and positioning a second insert within the second recessed area and against the second seal. | 06-19-2014 |
20150068485 | CYLINDER HEAD HAVING WEAR RESISTANT LASER PEENED PORTIONS - A cylinder head for an internal combustion engine system is disclosed. The cylinder head has at least one fuel injector. Further, the cylinder head has at least one valve reciprocally moveable with at least one valve guide disposed within the cylinder head. The cylinder head includes a portion. The portion defines an injector mount surface. The cylinder head also includes at least one injector bore disposed within the cylinder head. The injector bore is structured and arranged to receive the injector therein. The cylinder head also includes a peening area being defined on the injector mount surface of the cylinder head. The peening area defines a region being laser peened, such that a compressive stress is induced in the peening area. The compressive stress is induced to an effective depth of approximately up to 2 mm from the injector mount surface. | 03-12-2015 |
20150105212 | SYSTEM AND METHOD FOR SALVAGING A PIN-BORE ASSEMBLY - A method for salvaging a surface of a pin-bore assembly associated with a carrier is provided. The method includes inserting a sleeve within a bore of the carrier. The method also includes installing a retention mechanism that secures the sleeve within the bore of the carrier. | 04-16-2015 |
20150107545 | METHOD OF REMANUFACTURING AN ENGINE - A method of remanufacturing an engine is provided. The method includes drilling a cylinder block to form at least one opening. The method further includes tapping the at least one opening to form screw threads. The method further includes securing a mounting boss to the cylinder block using the screw threads. | 04-23-2015 |
20150135545 | SYSTEM AND METHOD FOR REMANUFACTURING AN ENGINE BLOCK - The present disclosure is related to a method of determining a height of an upper surface of an insert relative to a top deck surface of a cylinder block. The method includes detachably coupling a fixture to the top deck surface of the cylinder block. The method also includes disposing a dial gauge on the top deck surface adjacent to each of a plurality of notches defined in the fixture. The method includes inserting a probe of a dial gauge through each of the plurality of notches to contact each of corresponding portions of the upper surface of the insert. The method also includes determining local heights of the upper surface of the insert relative to the top deck surface at the corresponding portions of the upper surface. The height of upper surface of the insert relative to the top deck surface is determined based on the local heights. | 05-21-2015 |
20150143890 | METHOD AND TOOL FOR CHECKING ALIGNMENT BETWEEN GEARS - The present disclosure relates to a method of checking an alignment between a first gear and a second gear using a tool is provided. The tool includes a base portion defining a longitudinal axis and an elongate portion extending from the base portion along a transverse axis perpendicular to the longitudinal axis. Further, the second gear is received in an inner bore of the first gear. The method includes inserting at least partially the base portion of the tool within an inner bore of the second gear. The method also includes inserting a first pin extending from the elongate portion within a space between adjacent teeth of the first gear. The method further includes determining that the first gear is aligned with the second gear if a second pin extending from the elongate portion is received within a space between adjacent teeth of the second gear. | 05-28-2015 |
20150159585 | SYSTEM AND METHOD FOR REPAIR OF CAST COMPONENT - A method for repairing a cast component having a damaged area is provided. The method includes scanning an area adjacent to the damaged area to create a scan. The method includes forming a dam with a void. The void has a profile corresponding to the scan. The method includes positioning the dam adjacent to the damaged area. The method includes heating the cast component. The method includes introducing a repair material into the dam. The method also includes cooling the cast component. The method further includes removing an excess material from the cast component. | 06-11-2015 |
