See full text

A cylinder liner sealing arrangement for an internal combustion engine including a cylinder block having cylinder bores, a cylinder head, a cylinder liner within each cylinder bore and a circumferential cut-out formed in the upper and outer surfaces of the cylinder liner. A circular sealing ring is positioned in the circumferential cut-out with the sealing ring contacting at least the cylinder block and the cylinder liner to form a coolant seal therebetween. The sealing ring includes a seal enhancing configuration formed on at least an outer circumferential surface of the sealing ring with the seal enhancing configuration including at least one of an arcuate portion of a “D” ring seal or a plurality of circumferentially extending ribs. Replacing the cylinder liner seal includes removing the cylinder head while maintaining the position of the cylinder liner within the respective cylinder bore, removing an upper liner seal from within the circumferential cut-out while maintaining the position of the cylinder liner within the cylinder bore, positioning a replacement sealing ring in the circumferential cut-out while maintaining the position of the cylinder liner within the cylinder bore and replacing the cylinder head on the cylinder block of the engine.
