New cylinder blocks have been introduced on the 4.236 engine for the Backhoe Loaders. They have a larger cylinder liner parent bore diameter. The outside diameter of the cylinder liner is also larger. There is no longer a flame ring on the liner. The change became effective with engine serial number LD70178U106654N. The engine serial number is located above the fuel injection pump on the block.(1) Outside diameter of cylinder liner.
