1. A reciprocating pump, comprising:
a fluid section comprising a plurality of fluid-displacing members, wherein each fluid-displacing member of the plurality of fluid-displacing members is configured to displace fluid through the reciprocating pump; and
a power section comprising a plurality of crossheads, wherein each crosshead of the plurality of crossheads is coupled to a respective fluid-displacing member of the plurality of fluid-displacing members, and wherein the power section is configured to actuate the fluid section by actuating the plurality of crossheads through respective crosshead bores formed through the power section, wherein the power section comprises:
a plurality of structural members;
a plurality of pairs of support plates, each pair of support plates of the plurality of pairs of support plates permanently joined to two structural members of the plurality of structural members, wherein each support plate of each pair of support plates comprises an interior surface; and
a plurality of pairs of arcuate crosshead guide sections, each arcuate crosshead guide section of the plurality of pairs of arcuate crosshead guide sections secured in place between two structural members of the plurality of structural members against a respective pair of support plates of the plurality of pairs of support plates, wherein each pair of arcuate crosshead guide sections of the plurality of pairs of arcuate crosshead guide sections comprises a top arcuate crosshead guide section and a bottom arcuate crosshead guide section configured to form a portion of a respective crosshead bore of the respective crosshead bores, and wherein each pair of arcuate crosshead guide sections is secured in place using clamping segments secured to interior peripheral edges of windows of the two structural members of the plurality of structural members by bolts extending through interior passages of the clamping segments and having threads configured to mate with threaded holes extending into the interior peripheral edges of the windows of the two structural members.
