Abstract: A method of remanufacturing an engine block is provided. An insert is removed from a recess in a top deck of the engine block that surrounds a cylinder bore in the engine block. A used cylinder liner is removed from the cylinder bore. The used cylinder liner has a flange on an upper edge thereof having a first thickness. The recess in the top deck of the engine block is cleaned. A replacement cylinder liner is positioned in the cylinder bore. The replacement cylinder liner has a flange on an upper edge thereof that is received in the cleaned recess. The flange of the replacement cylinder liner has a second thickness that corresponds to the sum of the first thickness and the depth of the cleaned recess.

Abstract: A cylinder block for a fluid pump includes a cylindrical body having a hub bore and a plurality of cylinder bores arranged about the hub bore, a hub insert disposed in the hub bore, and an anti-rotation body configured to prevent rotation of the hub insert relative to the cylindrical body. The cylindrical body and the hub insert together define a channel in which the anti-rotation body is inserted.
