Abstract: A method for restoring a crack formed within a turbo charger engine transition section, the method including preparing a crack in the transition section to receive a material within the crack, applying the material within the crack, and retaining structural integrity of the transition section proximate the crack while at least one of preparing the crack and applying the material.

Abstract: A method of assembling a bore repair assembly for use with a wind turbine. The wind turbine includes a gearbox assembly that defines a first bearing bore and a second bearing bore coaxially aligned with the first bearing bore. The method includes coupling a first support assembly with respect to the second bearing bore. A boring bar is positioned coaxially within the first bearing bore and through the second bearing bore. The boring bar is rotatably coupled to the first support assembly. A boring bar drive assembly is coupled to the boring bar for rotating the boring bar about a central bearing axis.

Abstract: Method includes applying additive material to a pre-selected region of a rotor for use in a Roots type blower assembly. The additive material restores structural dimension to provide measured rotor-to-rotor clearance and/or rotor-to-case clearance within the predetermined clearance range. The additive material may be an epoxy paint material or a plating material. The method includes measuring the clearances, preparing the rotor surface, applying the additive material, and re-measuring the clearance. The restored rotor may be returned to service, for example, in a locomotive diesel. The disclosure also provides a restored rotor including at least one region comprising the additive material. Additionally, the disclosure provides an apparatus including a dimensionally restored rotor.

Abstract: A method of repairing a nozzle segment is provided. The nozzle segment includes at least one airfoil extending between an inner band and an outer band, and the airfoil includes a first sidewall and an opposing second sidewall that are joined together at a leading edge and at an axially-spaced trailing edge. The method includes identifying a damaged portion of the airfoil, repairing the damaged portion of the airfoil by at least one of welding weld filler in the area of the damaged portion of the airfoil, and brazing preform in the area of the damaged portion of the airfoil, and blending at least one of the weld filler and the preform to remove excess material to facilitate finishing an outer surface of the airfoil.

Abstract: A method for restoring a crack formed within a turbo charger engine transition section, the method including preparing a crack in the transition section to receive a material within the crack, applying the material within the crack, and retaining structural integrity of the transition section proximate the crack while at least one of preparing the crack and applying the material.

Abstract: A method for restoring a length of at least one of a master rod and an articulating rod, the method including determining a length of the rod, if the rod is within an acceptable length, cleaning the rod, applying a masking material to a part of the rod to be protected, grit blasting the part of the rod not protected by the masking material, and applying a thermal spray to the part of the rod not protected by the masking material to increase the length of the rod.

Abstract: A method for restoring a piston pin and/or an articulating pin after operating in an engine, the method includes removing material from the pin so that the pin has a concentric shape, conditioning the pin to accept application of a new material, and plating the outer diameter of the pin so as to restore the pin to near original dimensions.
