CYLINDER BLOCK EM-127 < DISASSEMBLY AND ASSEMBLY > C D E F G H I J K L M A EM N P O Measure the outer diameter of piston pin with a micrometer (A). Connecting Rod Bushing Oil Clearance (Connecting rod bushing oil clearance) = (Connecting rod bushing inner diameter) – (Piston pin outer diame- • If the calculated value exceeds the limit, replace connecting rod assembly and/or piston and piston pin assembly. • If replacing piston and piston pin assembly, refer to • If replacing connecting rod assembly, refer to to select the connecting rod bearing. Factory installed parts grading: • Service parts apply only to grade “0”. Unit: mm (in) *: After installing in connecting rod CYLINDER BLOCK DISTORTION • Using a scraper, remove gasket on the cylinder block surface, and also remove engine oil, scale, carbon, or other contamination. CAUTION: Be careful not to allow gasket flakes to enter engine oil or engine coolant passages.
