Abstract
A method for repairing a cylinder liner includes: placing a cylinder liner having a first inner diameter and a first outer diameter into a cavity of a confinement, the cavity including a cavity inner diameter that is substantially the same as the first outer diameter of the cylinder liner; heating the cylinder liner to a temperature at which the cylinder liner undergoes plastic deformation, causing the first inner diameter of the cylinder liner to decrease; and cooling the cylinder liner. The cooled cylinder liner has a second inner diameter that is less than the first inner diameter. An apparatus for repairing a cylinder liner includes a confinement having a cavity and a fluid passageway for controlling the temperature of the confinement, and a heating block for heating the cylinder liner when the cylinder liner is inserted into the cavity.
