A cast power end frame comprising a pair of end plates and an outer casing extending between the end plates and defining an interior therein;
- a crank shaft housing extending between the end plates and within the interior of the outer casing, and a plurality of crosshead tubes, each crosshead tube extending substantially perpendicular to the crank shaft housing, wherein the outer casing, crank shaft housing, and crosshead tubes are cast as a single part comprising steel comprising a carbon constituent of 0.06%-1.99% carbon.
A core segment comprising a front portion from which projects a crosshead plug, a first side comprising a first engagement feature, and a second side comprising a second engagement feature, wherein the first engagement feature of the core segment is adapted to engage with the second engagement feature of an adjacent, second core segment, and wherein a plurality of the core segments are stackable horizontally, such that adjacent ones of the core segments engage with each other to form a modular core comprising parallel crosshead plugs for use when casting the power end frame.
