  • Patent number: 9581173
    Abstract: 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.

  • Patent number: 9404843
    Abstract: 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.

  • Patent number: 9382871
    Abstract: 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.

  • Publication number: 20150068485
    Abstract: A cylinder head for an internal combustion engine system is disclosed. The cylinder head has at least one fuel injector. Further, the cylinder head has at least one valve reciprocally moveable with at least one valve guide disposed within the cylinder head. The cylinder head includes a portion. The portion defines an injector mount surface. The cylinder head also includes at least one injector bore disposed within the cylinder head. The injector bore is structured and arranged to receive the injector therein. The cylinder head also includes a peening area being defined on the injector mount surface of the cylinder head. The peening area defines a region being laser peened, such that a compressive stress is induced in the peening area. The compressive stress is induced to an effective depth of approximately up to 2 mm from the injector mount surface.

  • Publication number: 20110179947
    Abstract: A hydraulic pump can be remanufactured to save the investment in its components that are not seriously worn or failed. Some of the worn components, such as the pump barrel and yoke, can be salvaged by replacing or rebuilding the worn features. In particular, a worn internal spline on the pump barrel can be replaced by a spline insert that is threaded to the pump barrel and includes a new internal spline. A worn actuation tab on a yoke for contacting an actuating piston can be replaced by adding a new tab wear button.
