摘要：
A pump including a power end (202) and a fluid end (204). A bore (214) extends through the fluid end (204). A rod (212) is disposed in the bore (214) of the fluid end (204) and extends into the power end (202). The rod (212) includes a reduced diameter portion (222) and the rod (212) is configured to connect the power end (202) and the fluid end (204). The pump also includes a retaining apparatus (216) coupled to the reduced diameter portion (222) of the rod (212). A shoulder (218) is formed between a first inner diameter (226) of the bore (214) and a second inner diameter (228) of the bore (214). The first inner diameter (226) is smaller than an outer diameter of the retaining apparatus (216). A first end (260) of the retaining apparatus (216) is configured to contact the shoulder (218) and a second end (262) of the retaining apparatus (216) is configured to contact a contact surface formed on the rod (212) in order to restrict movement of the rod (212) within the bore (214).
