EM-112 < DISASSEMBLY AND ASSEMBLY > [HR16DE] CYLINDER BLOCK Cylinder Bore Inner Diameter • Using a bore gauge, measure the cylinder bore for wear, out-of- round and taper at six different points on each cylinder. (“X” and NOTE: • 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. Piston to Cylinder Bore Clearance Calculate by piston skirt diameter and cylinder bore inner diameter (direction “X”, position “B”). • If it exceeds the limit, replace piston and piston pin assembly and/or cylinder block. CRANKSHAFT MAIN JOURNAL DIAMETER • Measure the outer diameter of crankshaft main journals with a micrometer (A). • If out of the standard, measure the main bearing oil clearance. Then use undersize bearing. A : Unit: mm (in) Standard: Cylinder bore inner diameter : Refer to . Limit: Out-of-round (Difference between“X”and“Y”) Taper (Difference between“A”and“B” : Refer to .
