    摘要： A method of fixing an annular piston onto a piston shaft includes providing an annular piston with a central bore having a diameter slighty less than the shaft diameter, heating the annular piston to expand the bore diameter and then placing the heated piston onto the shaft so that the piston, upon cooling, is permanently shrink-fit onto the shaft. In an end-of-car cushioning unit for a railway car, the prior shaft is cut adjacent the piston and the piston is rebored to a diameter slightly less than the diameter of the end portion of the piston onto which it is to be shrink-fitted.

    摘要： 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.

    摘要： A method for repair of a cylinder block including a water ferrule having damage in an area proximate to the water ferrule is disclosed. The repair method includes removing material from the area containing and surrounding the damage. The method also includes providing a counter bore sized to surround the removed material. The counter bore is configured to define a seat at the one end of the water ferrule. A sealing member is aligned and introduced into the seat of the counter bore. The method includes aligning a stepped insert coaxially with the sealing member and the seat. The method also includes a step of introducing the insert into the seat of the counter bore to form an interference fit therewith. The method further includes providing a seal formed by a combination of the sealing member and the insert within the seat of the counter bore.
