Abstract: A manifold assembly configured for use with a fluid end used in oil and gas operations. The manifold assembly comprises upper and lower manifolds supported on side posts such that the manifolds and posts define a central opening. In operation, the fluid end is positioned within the central opening such that the manifold assembly surrounds the fluid end. The manifold assembly is not attached to the fluid end other than flexible conduits interconnecting the fluid and the manifolds. The manifold assembly is modular and when assembled, may be moved together as a single unit.

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.
