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: A method is provided for remanufacturing an engine block. The engine block includes a top deck and a passageway that opens at the top deck, and is partially defined in the engine block by a counterbore having a side surface and a base surface. The method includes spraying solid powder metal onto the side surface and the base surface by a gas dynamic cold spray method so as to form a fill member adhered with the side surface and the base surface.

Abstract: A process for remanufacturing a cylinder head that includes a worn or damaged rocker arm stand adapted to receive a rocker shaft to which at least one rocker arm is mounted, the steps including machining a channel in a surface of the worn or damaged rocker arm stand, securing an insert into the channel, and machining the insert to form a remanufactured inner facing surface. The remanufactured cylinder head includes at least one rocker arm stand that has a machined channel with a remanufactured insert secured therein, the rocker shaft being disposed adjacent the inner facing surface, not the rocker arm stand.

Abstract: An insert for use in a remanufactured cylinder head rocker arm stand, the insert comprising an inner facing surface having a radius within a range of 35 to 45 mm and a length within a range of 70 to 103 mm, and an outer facing surface adapted for disposal against a channel in the rocker arm stand, the rocker arm shaft being disposed adjacent the inner facing surface in use, but not adjacent the rocker arm stand.

Abstract: A hydraulic pump can be remanufactured to save the investment in its components that are not seriously worn or failed. Some of the worn components, such as the pump barrel and yoke, can be salvaged by replacing or rebuilding the worn features. In particular, a worn internal spline on the pump barrel can be replaced by a spline insert that is threaded to the pump barrel and includes a new internal spline. A worn actuation tab on a yoke for contacting an actuating piston can be replaced by adding a new tab wear button.

Abstract: A method for predicting performance of a future product is disclosed. The method includes generating historical data for at least one product and generating a Failure Mode and Effects Analysis (FMEA) for the at least one product. The method also includes determining a relationship between an FMEA indicator of the FMEA generated for the at least one product and the historical data for the at least one product. The method further includes generating an. FMEA for the future product and applying the determined relationship to the FMEA indicator from the FMEA generated for the future product to predict performance for the future product.
