  "abstract": "A power end frame of a reciprocating pump includes a plate and a ring configured to couple to the plate in an assembled configuration of the power end frame. The ring and the plate cooperatively define a compartment of an interior of the power end frame configured to enclose a crankshaft of the reciprocating pump, the ring includes a base surface and a flange extending from the base surface such that an interface surface of the flange is offset from the base surface, the base surface faces the compartment of the power end frame, and the interface surface is configured to abut the plate in the assembled configuration.",
