Abstract
A method and apparatus for a reciprocating pump assembly, including a crosshead and a connecting rod. The crosshead includes a main body having a cylindrical bore formed therethrough and defining a bearing surface, and a window formed through the main body and into the cylindrical bore. The connecting rod includes a small end disposed within the cylindrical bore and a beam portion extending through the window and being connected to the small end. In an exemplary embodiment, a bearing including a tubular body and a cutout is disposed within the cylindrical bore. In another exemplary embodiment, a clamp engages both the main body of the crosshead and the respective opposing end portions of the small end, thus reducing axial displacement of the small end relative to the crosshead.
