A fluid end assembly of a hydraulic fluid pump includes a housing, a plug member, a lock cover, and at least one retention pin. The housing may include at least one bore. The plug member may be positioned at least partially within the at least one bore. The lock cover may be coupled to the housing and configured to retain the plug member within the at least one bore during operation of the fluid end assembly. The at least one retention pin may extend at least partially through a portion of the lock cover to retain the lock cover in a rotational position that retains the plug member at least partially within the bore.

Fluid end of a hydraulic fluid pump and method of assembling the same

A method of assembling a fluid end includes inserting a valve through a bore of a housing of the fluid end and into an interior volume of the fluid end, inserting a valve cover into the bore such that the valve cover seals the bore, and coupling a lock cover to the housing, the lock cover positioned over the bore to prevent removal of the valve cover from the bore. When the lock cover is coupled to the housing, the lock cover does not apply a preload against the valve cover.
