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

A method of assembling a fluid end of a hydraulic fluid pump, the method comprising:

• inserting a plug member into a bore of a housing of the fluid end;
• coupling a handle to a lock cover by inserting an extended portion of the lock cover into an opening defined by a ring portion of the handle to abut the ring portion of the handle against a flange of the lock cover, wherein the handle comprises a pair of elongated portions extending from the ring portion radially beyond the ring portion, as well as an engagement portion extending between and connected to the pair of elongated portions at a distal end of the pair of elongated portions, the distal end being positioned outward of the ring portion;
• coupling the lock cover to the housing via the engagement portion of the handle such that the lock cover is positioned over the plug member and retaining the plug member in the bore, wherein the lock cover comprises threads, the and a flange of the lock cover extends radially beyond the threads, and the extended portion of the lock cover extends from the flange away from the threads;
• and
• inserting a magnetic retention pin through the flange of the lock cover.

A fluid end assembly of a hydraulic fluid pump comprising:

• a housing having a first bore;
• a plug member positioned at least partially within the first bore;
• a lock cover axially aligned with the first bore of the housing and comprising a first surface, wherein the first surface of the lock cover is configured to extend within a second bore of a lock coupled to the housing and to engage with a second surface of the lock within the second bore, the lock cover is configured to rotate between an unlocked position and a locked position, the lock cover is configured to retain the plug member within the first bore when in the locked position, the lock cover comprises a flange that extends radially beyond the first surface, the flange comprises a first aperture, and the lock cover comprises an extended portion that extends from the flange and away from the first surface;
• a handle comprising a ring portion that defines an opening, a pair of elongated portions extending from the ring portion radially beyond the ring portion, and an engagement portion extending between and connected to the pair of elongated portions at a distal end of the pair of elongated portions, wherein the extended portion of the lock cover is inserted into the opening of the ring portion of the handle, the ring portion comprises a second aperture configured to align with the first aperture of the flange of the lock cover for insertion of a fastener that couples the handle and the lock cover to one another, and the distal end is positioned outward of the ring portion;
• and
• a magnetic retention pin extending through the flange of the lock cover to retain the lock cover in the locked position.
