1. An apparatus, comprising:
a power end of a reciprocating pump assembly, the power end comprising:
a crosshead block formed of a solitary integral mass and having a plurality of bores therethrough, at least one bore of the plurality of bores having a lubrication port and a drain port therein;
a manifold in fluid communication with the lubrication port;
a pump in fluid communication with the manifold,
wherein the pump is operable to pump a lubrication fluid to the crosshead block, via the manifold, and
wherein the lubrication port is configured to pass the lubrication fluid into the bore so that a crosshead disposed within the bore is lubricated as it reciprocates within the bore.
