Engine Assembly (0-02) Section 0 - Engine Disassembly and Assembly - Group 00 M11 Page 0-54 Inspect the liner and cylinder block for dirt or damage. Replace the liner if it is damaged. Install the liner again. Measure the liner bore for out-of-roundness at points ‘‘C’’, and Measure each point in the di- rection ‘‘AA’’ and ‘‘BB’’. The bore must not be more than 0.10 mm [0.004 inch] out-of-round. NOTE: The cylinder block can be distorted when mounted on the engine rebuild stand. If the liner bore does not meet the specifications, remove the engine from the engine re- build stand and set it on a clean flat surface. Measure the liner bore out-of-roundness again.
If the liner bore is more than 0.10 mm [0.004 inch] out- of-round with the engine on a flat surface: Remove the liner so the cylinder block liner bore can be measured. NOTE: The block counterbore diameters above and below the cylinder block counterbore area are not critical dimen- sions and do not need to be measured.
