Abstract: A method of remanufacturing a piston includes machining an exterior surface of a body of the piston to define a reference surface. The reference surface is inwardly offset relative to a portion of the exterior surface adjacent the reference surface. The body is made from a body material comprising a metal. A layer of a cold spray powder is applied to the reference surface via cold spraying to define a piston blank surface. The piston blank surface is outwardly offset relative to the portion of the exterior surface adjacent the reference surface. The cold spray powder is made from a powder material comprising the metal. The piston blank surface is machined to define a piston finish surface. The piston finish surface has a dimension which is within a predetermined range.

Abstract: A method of determining wear of a worn surface of a machine component includes providing a scanning device at a distance from the worn surface. The method also includes moving at least one of the scanning device and the worn surface relative to the other and generating a set of data points via the scanning device. Each data point of the set of data points is indicative of a depth of a corresponding point on the worn surface relative to a reference plane. The method further includes determining a maximum depth of the worn surface based on the set of data points and comparing the maximum depth to a reference value to determine a next step in a remanufacturing process of the machine component.

Abstract: 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.
