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: A method for repairing a worn portion in an inner diameter surface of a bore of a cast iron part is disclosed. The inner diameter surface of the bore may have an original surface geometry prior to wear. The method may comprise forming a crescent-shaped pocket in the inner diameter surface of the bore to remove the worn portion, installing an insert in the crescent-shaped pocket, and post-machining the insert to form a crescent-shaped insert that is flush with the original surface geometry of the bore inner surface diameter.

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.
