    Abstract: The disclosure relates to a piston ring removal tool and methods of using the same. One method includes disposing a tool between a first piston ring and a piston associated with the piston ring and rotating the piston, wherein the tool engages the first piston ring and separates at least a portion of the first piston ring from the piston.

    Abstract: Remanufacturing a used cylinder liner includes receiving a used cylinder liner having a fillet relieved of residual compressive stress via service in an engine, and compressing a material substrate of the cylinder liner forming a fatigue sensitive fillet, such that a non-uniform profile of the fillet is reshaped via plastic deformation of the material substrate. Residual compressive stress is restored to the fillet at least in part via the plastic deformation. A mask and used cylinder liner assembly for processing the used cylinder liner during remanufacturing is also disclosed.

    Abstract translation: 二次汽缸套的再制造包括：通过在发动机中使用而接收具有消除残余压缩应力的圆角的二次汽缸套，以及压缩形成疲劳敏感内圆角的气缸套的材料基底，使得圆角的不均匀轮廓 通过材料基板的塑性变形而重新形成。 至少部分通过塑性变形将剩余压应力恢复到圆角。 还公开了一种用于在再制造期间处理二手汽缸套的掩模和二次汽缸套组件。

    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.
