CYLINDER BLOCK EM-235 < UNIT DISASSEMBLY AND ASSEMBLY > [MR20DD] C D E F G H I J K L M A EM N P O Cylinder Bore Inner Diameter • Using a cylinder gauge, measure the cylinder bore for wear, out-of- round and taper at six different points on each cylinder. [ and directions at , , and ] [ is in longitudinal direction of engine] NOTE: direction at position. • If the measured value exceeds the limit, or if there are scratches and/or seizure on the cylinder inner wall, replace cylinder block. Piston Skirt Diameter Measure the outer diameter of piston skirt with a micrometer (A). Piston to Cylinder Bore Clearance Calculate by piston skirt diameter and cylinder bore inner diameter position ].
