Abstract: A repaired piston includes a crown composed of base and welding filler materials, and having an annular rim extending around a combustion bowl. A finite number of repaired defects are within the annular rim, and have a spatial distribution limited by a multidirectional spacing parameter, and a size distribution limited by a unidirectional sizing parameter.

Abstract: Remanufacturing a variable displacement swash plate-type hydraulic device includes receiving a body of a used hydraulic device defining first and second actuator guide bores, at least one of which is out of specifications for guiding a swash plate linear actuator. The method further includes removing material forming the first and second guide bores, and interference fitting first and second sleeves into the body in place of the removed material. Additional material is removed from the first and second sleeves to form new first and second actuator guide bores, each satisfying specifications for guiding a swash plate linear actuator.
