1. A method comprising:
removing a worn portion from a first end face of a component of a rotary pressure exchanger, the component being a rotor or an end cover, wherein the rotary pressure exchanger is configured to exchange pressures between a first fluid and a second fluid, wherein the worn portion is a substantially cylindrical shape, wherein a distal end surface of the substantially cylindrical shape spans from a first radial side of the component to a second radial side of the component, wherein the component includes a removable end portion that has a fixed length and that is detachably connected to a body of the component; and
coupling a first end face of a component replacement piece of the rotary pressure exchanger to the first end face of the component to replace the worn portion, wherein the component forms a first plurality of apertures configured to align with a second plurality of apertures of the component replacement piece, wherein a manifold of the rotary pressure exchanger is fluidly coupled to the component, and wherein the manifold comprises a fluid chamber, an inlet port, and an outlet port configured to transfer one of the first fluid or the second fluid.
