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 remanufactured piston for an internal combustion engine includes a crown and a skirt. A piston body includes a first piston body end within the crown and an opposite second piston body end. The crown further includes an annular crown body having an annular crown body edge. The first piston body end further includes an annular piston body edge. The annular piston body edge and the annular crown body edge form a joint, and a metallurgical bond attaches the annular crown body to the piston body at the joint.

Abstract: A magnetic particle inspection tool is provided including a yoke with an inspection magnet, a first magnetic member, and a second magnetic member. The inspection magnet is configured to magnetize a work piece. The first magnetic member is rotatable relative to the inspection magnet between a first position and a second position, and the inspection magnet is slidable relative to the first magnetic member. The first magnetic member and second magnetic member include a plurality of magnetic sources forming a magnetic surface with a first magnetic pattern and a magnetic surface with a second magnetic pattern. The magnetic surfaces are magnetically attracted when the first magnetic member is in the first position and repelled when in the second position.

Abstract: An adjustable electric coil for magnetic particle inspection has a plurality of telescopically interconnected sections. Each of the interconnected sections includes a connector element and a conducting element. The conducting element is joined at a proximal end to an end surface of a peripheral wall of the connector element, and a central opening is defined through the connector element on one side of the conducting element. The conducting element of each section is inserted through the central opening of an adjacent connector element of an adjacent section.

Abstract: A method for inspecting for discontinuities in a hole comprises inserting a probe including a first location having a first magnetic plarity and a second location having a second polarity into the hole, wherein the first location and second location have different magnetic polarities, creating a magnetic field between the first location and the second location within the interior of the hole, and detecting a discontinuity in the hole using the magnetic field.

Abstract: A method of repairing a cast iron component is disclosed. The method may include removing a damaged or defective portion of the cast iron component, and pre-heating the cast iron component to a temperature in a range from 200-800 degrees F. After pre-heating, the method may include welding a removed area of the cast iron component using a Cold Metal Transfer (CMT) process with a consumable wire electrode made from one of a carbon steel alloy, a nickel alloy, or a nickel-iron alloy material having a Coefficient of Thermal Expansion (CTE) that is within ±10% of a CTE of the cast iron material of the cast iron component to fill the area where the damaged or defective portion was removed. After welding, the cast iron component may be cooled and the welded portion of the cast iron component may be final machined.

Abstract: A method of configuring an eddy current detector to measure a thickness of a coating on a substrate includes measuring an impedance of the coated substrate, and establishing an impedance plane plot using a computer. The method may also include determining a rotation angle. The rotation angle may be an angle of rotation of the impedance plane plot that will make the inductive reactance component of the impedance substantially insensitive to substrate electrical conductivity within a coating thickness range. The method may further include establishing a calibration curve that is substantially insensitive to substrate electrical conductivity using the rotation angle. The calibration curve may be a curve that relates the inductive reactance component of the impedance to coating thickness.

Abstract: A method of repairing a metallic component is disclosed. The method may include machining away a damaged first portion of the component, and machining away a second portion of the component adjacent the damaged first portion, the second portion being an area that would be subject to distortion resulting from solidification of molten weld material added to repair the damaged first portion. The method may also include inserting a dam made of a high-temperature-resistant material adjacent the machined away second portion to contain molten weld material added to the machined away second portion. Oxy-fuel welding may be performed to at least partially fill the machined away damaged first portion of the component and the machined away second portion of the component, and final machining of the welded portions may be performed.
