New cylinder blocks have been introduced on the 4.236 engine. The 4.236 engine has a larger cylinder liner parent bore diameter and the outside diameter of the cylinder liner is also larger. The liners will no longer have a flame ring. Effective with this change only flanged liners will be available. The change became effective at engine serial number LDU106654N and up. See General Information in Systems Operation for the serial number location.(1) Outside diameter of cylinder liner.Earlier engines with thin wall liners: Production liner ... 103.238 to 103.264 mm (4.0645 to 4.0655 in)Service liner ... 103.188 to 103.213 mm (4.0625 to 4.0635 in)Current engines with thick wall liners: Production liner ... 104.254 to 104.280 mm (4.1045 to 4.1055 in)Service liner ... 104.204 to 104.229 mm (4.1025 to 4.1035 in)(2) Inside diameter of cylinder liner: Production liner ... 98.48 to 98.50 mm (3.877 to 3.878 in)Service liner ... 98.50 to 98.53 mm (3.878 to 3.879 in)Maximum diameter wear (when new liners are needed ... 0.20 mm (0.008 in)Transition fit of service liner in cylinder block ... 0.03 mm ( 0.001 in)Length of cylinder liner with flame ring ... 227.10 to 227.43 mm (8.941 to 8.954 in)Length of cylinder liner without flame ring ... 226.03 to 226.82 mm (8.899 to 8.930 in)(3) Liner (flange) projection [do not measure from flame ring (if equipped)] ... 0.10 mm (0.004 in) above to 0.10 mm (0.004 in) below face of cylinder block.
