摘要： An improved sealing arrangement 40 is provided for a replaceable cylinder liner 10. The sealing arrangement 40 includes a seal 26 in the form of a band that is positioned in an annular groove 28 under a flange seat 20 of the cylinder liner 10. The annular groove 28 includes a first and a second undercut 30,34 that provides a relief area for the seal 26 to deflect into lessening the opportunity of damage to the seal 26. The first and second undercuts 30,34 also relieve stress in the axial direction improving the fatigue life of the cylinder liner10.
