Abstract: A pair of wear grooves for a linear drive assembly. One wear groove is disposed on a wear plate attached to a crosshead. This wear groove is on a front edge of the wear plate, and does not intersect any lubrication groove. Another wear groove is disposed circumferentially about an inner wall of a crosshead guide. Each of the wear grooves is observable to an operator without fully disassembling the crosshead and the crosshead guide, and each is observable from a single side of the crosshead guide. Should the wear groove not be observable, the associated component should be replaced. Should the wear groove be observable, the remaining life of the component can be determined from the groove's depth.

Abstract: A fluid end is formed from a first body attached to a separate second body. Each body includes an external surface. When the bodies are attached, their respective external surfaces are in flush engagement. A plurality of bores are formed in the second body that are alignable with a plurality of corresponding bores formed in the first body. The fluid end may be used with seals disposed within recesses within each bore to seal against corresponding sealing surfaces. Further, retaining closures may be bolted to the fluid end bodies, such that the closures have a threadless connection to the fluid end bodies. Various combinations of such components may be utilized.

Abstract: A fluid routing plug for use with a fluid end section. The fluid end section being one of a plurality of fluid end sections making up a fluid end side of a high pressure pump. The fluid routing plug is installed within a horizontal bore formed in a fluid end section and is configured to route fluid between an intake and discharge bore. The fluid routing plug comprises a plurality of first and second fluid passages. The first and second passages do not intersect and are offset from one another. The first fluid passages are configured to direct fluid delivered to the horizontal bore from intake bores towards a reciprocating plunger. The second fluid passages are configured to direct fluid pressurized by the plunger towards a discharge bore.
