A compressor housing defines an inlet bore having a first inlet collar disposed therein. The inlet collar is connected to the housing with a first plurality of radially extending posts. The first plurality of posts is removed to detach the inlet collar from the housing, and the inlet collar is removed from the housing. The same or another inlet collar is concentrically located within a liner. The liner can be located at a radial distance around at least a portion of the inlet collar. The inlet collar is connected to the liner by radially inserting a second plurality of posts through the liner and into the inlet collar. An assembly of the liner containing the inlet collar is inserted into the inlet bore of the housing such that the inlet collar forms the inducer bore of the compressor housing.

Compressor housing remanufacturing method and apparatus

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

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, positioning a first insert within the first recessed area, 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, and positioning a second insert within the second recessed area.

Method of manufacturing an engine block

The present disclosure, in one form, provides a process for remanufacturing a flanged cylinder liner, comprising the steps of machining a top portion of the cylinder liner to remove the cylinder liner flange, thereby creating a flange seat portion, preparing the top portion of the cylinder liner to receive a replacement cylindrical flanged sleeve collar, aligning the center axis of the cylinder liner with the center axis of the cylindrical flanged sleeve collar, placing the sleeve collar into contact with the cylinder liner such that the cylindrical flanged sleeve collar abuts with the flange seat portion and affixing the cylindrical flanged sleeve collar onto the liner.

Remanufactured cylinder liner flange replacement

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 refurbishing a camshaft () having at least one defective portion () includes removing material from the at least one defective portion () to create a neck region (). An alignment feature () is introduced in the neck region () according to a previous orientation of the defective portion (). A segmented blank () is installed around the neck region () and oriented with the alignment feature ().
