摘要： Aspects of the present disclosure relate to retainer nut locking apparatus and methods for fluid ends, and associated components thereof. In one implementation, a method of operating a fluid end includes installing a retainer nut assembly on a fluid end body by turning a retainer nut in an installation direction and into a bore formed in the fluid end body. The retainer nut has a first surface that faces away from the fluid end body and a second surface that faces that fluid end body. The method also includes rotating a locking tab in a locking direction and into contact with an inner surface of the fluid end body. The locking direction is opposite of the installation direction. The locking tab is disposed inside the bore and adjacent to the second surface of the retainer nut.
