Abstract: A process for remanufacturing a cylinder head that includes a worn or damaged rocker arm stand adapted to receive a rocker shaft to which at least one rocker arm is mounted, the steps including machining a channel in a surface of the worn or damaged rocker arm stand, securing an insert into the channel, and machining the insert to form a remanufactured inner facing surface. The remanufactured cylinder head includes at least one rocker arm stand that has a machined channel with a remanufactured insert secured therein, the rocker shaft being disposed adjacent the inner facing surface, not the rocker arm stand.

Abstract: An insert for use in a remanufactured cylinder head rocker arm stand, the insert comprising an inner facing surface having a radius within a range of 35 to 45 mm and a length within a range of 70 to 103 mm, and an outer facing surface adapted for disposal against a channel in the rocker arm stand, the rocker arm shaft being disposed adjacent the inner facing surface in use, but not adjacent the rocker arm stand.

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.

Abstract: A method of refurbishing a camshaft (100) having at least one defective portion (202, 206) includes removing material from the at least one defective portion (202, 206) to create a neck region (302). An alignment feature (402) is introduced in the neck region (302) according to a previous orientation of the defective portion (202, 206). A segmented blank (1008) is installed around the neck region (302) and oriented with the alignment feature (402).

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.

Abstract: A method for predicting performance of a future product is disclosed. The method includes generating historical data for at least one product and generating a Failure Mode and Effects Analysis (FMEA) for the at least one product. The method also includes determining a relationship between an FMEA indicator of the FMEA generated for the at least one product and the historical data for the at least one product. The method further includes generating an FMEA for the future product and applying the determined relationship to the FMEA indicator from the FMEA generated for the future product to predict performance for the future product.

Abstract: In a hydraulic pump assembly, an annular sleeve member is radially interposed between an outer peripheral surface portion of an input shaft and an inner peripheral surface portion of a cylinder block or barrel within which are provided a plurality of piston cylinders for accommodating a plurality of pumping pistons. The outer peripheral surface portion of the input shaft includes an outer peripheral splined section, and the inner peripheral surface portion of the cylinder block or barrel includes an inner peripheral splined section. The annular sleeve member is provided with the inner peripheral splined portion for splined engagement with the outer peripheral splined portion of the input shaft and with the outer peripheral splined portion for engagement with the inner peripheral splined portion of the cylinder block or barrel. In this manner, a dual splined interconnection system is defined between the input shaft, the annular sleeve member and the cylinder block or barrel.
