Abstract: A relief valve assembly includes a housing assembly defining a chamber therein. The relief valve assembly includes a piston. The piston may be at least partially disposed within the chamber. The relief valve assembly includes a pilot inlet. The pilot inlet may be configured to provide a pilot pressure proximate a second end of the chamber. The relief valve assembly includes an overpressure inlet sealed from a first end of the chamber by the piston. The overpressure inlet may be configured to provide an inlet pressure which may actuate the piston when the inlet pressure exceeds the pilot pressure.

Abstract: A power end frame includes a housing and a face plate secured to the housing. During use, components of the power end frame, including the housing and the face plate, are subjected to large tensile stresses. This disclosure describes a method of imparting compressive stresses in the power end frame to resist these large tensile stresses.

Abstract: A method for manufacturing an engine block is disclosed. In embodiments, the method includes forming an expansion hole in a block body of the engine block that encircles an engine block bore at a head face of the engine block. The method also includes placing an insert into the expansion hole, the insert including an insert body. The method further includes placing a reaction material between the insert and the block body. The method yet further includes forming an insert bond layer between the insert and block body using the reaction material. The method still further includes forming an insert bore through the insert body.

Abstract: A method of manufacturing an engine block is disclosed. In one embodiment, the method includes providing an engine block including a cylinder bore and a top deck with a head face including a predetermined surface roughness. The method also includes masking the cylinder bore with a masking plug, the masking plug being located at a predetermined insertion distance measured from a masking plug outer surface to the head face. The method further includes applying a corrosion resistant coating to the top deck over the head face and machine finishing the engine block including the coating to the engine block specifications.
