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.

High-pressure rotating fitting

A method for remanufacturing or repairing a cylinder head having a bore configured to receive a fuel injector comprises machining a portion of a surface forming the bore to remove imperfections, inserting a repair component into the bore proximate the machined portion of the bore, and spraying material into the bore proximate the machined portion and the repair component, thereby holding the component into place.

Fuel injector bore repair

A process of remanufacturing a component such as an attachment flange used in turbochargers is provided and includes using a steam oxidation process to form an adhesion layer on top of a sealing surface of the component. The adhesion layer is an oxidation layer that a thermal metal spray coating can be applied on top of in order to prevent spalling that can occur at high heat. Once the process is completed, the component can be inspected to ensure that it meets or exceeds the manufacturer's original specifications.

Steam oxidation of thermal spray substrate

A method of determining wear of a worn surface of a machine component includes providing a scanning device at a distance from the worn surface. The method also includes moving at least one of the scanning device and the worn surface relative to the other and generating a set of data points via the scanning device. Each data point of the set of data points is indicative of a depth of a corresponding point on the worn surface relative to a reference plane. The method further includes determining a maximum depth of the worn surface based on the set of data points and comparing the maximum depth to a reference value to determine a next step in a remanufacturing process of the machine component.

System and method for determining wear of a worn surface

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.

Top deck surface coating of engine block

Method of remanufacturing a component comprising: removing a damaged area of a cast iron component, the remaining component constituting a cast iron base; depositing molten particles on the cast iron base to form a pool of agglomerated molten particles, wherein the pool comprises aluminum and at least one of nickel, cobalt, chromium, silicon, or iron; cooling the pool to form a solid intermediate layer; and depositing solid particles on the solid intermediate layer to form an outer layer, wherein the solid particles comprise steel. Additionally, a component comprising: a cast iron base; an intermediate layer covering at least a portion of the cast iron base, wherein the intermediate layer comprises aluminum and at least one of nickel, cobalt, chromium, silicon, or iron; and an outer layer covering the intermediate layer, wherein the outer layer comprises steel.

Remanufacturing cast iron component with steel outer layer and remanufactured component

A method for manufacturing an engine block includes removing material from the top deck of the engine block surrounding a first opening to create a first recessed area, placing a first seal within the first recessed area, positioning a first insert within the first recessed area and against the first seal. The method may also include removing material from the top deck of the engine block surrounding a second opening to create a second recessed area that at least partially overlaps the first recessed area, placing a second seal in the second recessed area and positioning a second insert within the second recessed area and against the second seal.

Method of manufacturing an engine block

A power rail includes an aluminum body and a wear coating including stainless steel. The power rail may also include a break-in coating having a lower hardness than the wear coating.

Coated power rail

A method for manufacturing an engine block, such as for an internal combustion engine, includes a step of removing material from a top deck of the engine block surrounding a cylinder bore to create a first removal area. Material is also removed from the top deck of the engine block surrounding at least one fluid passage to create a second removal area. An insert is positioned within a recessed area defined by the first removal area and the second removal area.

A method of repairing a housing for a machine system includes returning an inner diameter of at least one bearing bore of the housing to a uniform diameter state. The at least one bearing bore is prepared for resurfacing via removing deeply entrapped grease from within pores in cast surface material of the housing subsequent to returning the inner diameter to a uniform diameter state. Subsequent to preparing the at least one bearing bore for resurfacing, it is resurfaced with a material different from cast material of the housing and bonded therewith, for example via thermal spray coating. Resurfacing a cast metallic component, of iron, steel, or the like with metal spray coating may include removing deeply embedded grease from pores of cast surface material of a cast component, in preparation for spraying the cast component with metal spray resurfacing material.

Repair and resurfacing methods for use in remanufacturing a machine system

This invention relates generally to a method for repairing a casting, and more specifically to a method of repairing a casting by pouring melted filler material into a damaged portion of the original casting. Damaged cast metal components, such as a cylinder head of an internal combustion engine are repaired by preheating the component to a first preheat temperature. The damaged area of the casting is then heated to a higher temperature using a torch and melted filler material is poured into the casting. The torch is used to maintain the temperature of the melted material for thirty seconds to two minutes. The temperature of the filler material is then cooled using compressed air.

Method for repairing a casting

A device adapted to respond to a mechanical shock as in an earthquake or the like, and including a first movable element to be controlled, a second element which normally blocks movement of the first element but is displaceable by shock-induced movement of a weight to permit movement of the first element, together with resetting mechanism operable to move the first element back toward its initial position and operable also to deflect the second element laterally back to an active position again blocking movement of the first element from its normal setting. The weight is preferably supported by a universal connection including a ball and socket joint in which the ball has an upper truncated portion defining a surface engageable with a movable part in a manner shifting that part axially in response to shock-induced pivotal movement of the weight structure.
