Abstract: A fitting has a first housing including a first body and a second body. The first body defines a first channel and a second channel, and second body defines a third channel that is co-planar with the first channel and a fourth channel that is co-planar with the first channel. First bearings are disposed within the first channel and the third channel, where the first bearings rotatably coupled the first housing to the second housing. Additionally, second bearings are disposed within the second channel and the fourth channel, the second bearings rotatably coupling the first housing to the second housing. A plug couples to the first housing, a gasket is disposed between the plug and the first housing, and a passage is defined at least in part by the first housing, the second housing, and the plug.

Abstract: A remanufactured pinion shaft includes a salvage member secured to a replacement member. The salvage member may be formed from a damaged pinion shaft and includes first gear teeth proximate a first axial end and a first alignment member proximate a second axial end. The replacement member includes second gear teeth proximate a first axial end and a second alignment member proximate a second axial end. The first alignment member and the second alignment member cooperate to transmit rotational motion between the first salvage member and the replacement member and/or align the salvage member relative to the replacement member.

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 cylinder head assembly includes a cylinder head having a top deck, a fire deck, and an igniter post extending upward from the fire deck. An igniter sleeve is within an igniter bore in the cylinder head and includes a locating surface clamped against an upward facing stop surface of the cylinder head. A tip coolant clearance is defined axially between a sleeve tip and the fire deck, and a body coolant clearance is defined peripherally between the igniter sleeve and the cylinder head and is continuously circumferential of the igniter sleeve axially between the sleeve tip and a coolant cavity formed in the cylinder head.

Abstract: A cylinder liner assembly is disclosed for use with an engine. The cylinder liner assembly may include a liner having a hollow generally cylindrical body extending from a top end to a bottom end along a longitudinal axis, and an internal annular cuff ring groove formed at the top end of the liner. An internal surface of the internal cuff ring groove may include a metal spray coating having a thermal conductivity that is less than a thermal conductivity of a base material of the liner to act as a thermal insulating layer. A cuff ring may be disposed within the internal cuff ring groove at the top end of the liner in contact with the metal spray coating. A seal may be disposed around an outer circumferential surface of the liner approximately in axial alignment with an internal axial end of the internal cuff ring groove.

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.

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.
