5 INSPECT PISTON SUB-ASSEMBLY WITH PIN a Using a micrometer, measure the piston diameter at a position that is 15 0 mm (0 591 in ) from the Standard diameter: 93.950 to 93.960 mm (3.6988 to 3.6992 in.) Minimum diameter: 93.815 mm (3.6935 in.) If the diameter is less than the minimum, replace the piston Fig. 111: Measuring Piston Diameter 6 INSPECT PISTON OIL CLEARANCE a Measure the cylinder bore diameter in the thrust direction b Subtract the piston diameter measurement from the cylinder bore diameter measurement Standard oil clearance: 0.040 to 0.062 mm (0.00157 to 0.00244 in.) Maximum oil clearance: 0.385 mm (0.0152 in.) If the oil clearance is greater than the maximum, replace all the pistons If necessary, replace the 7 INSPECT PISTON PIN OIL CLEARANCE a Check each mark on the piston, piston pin and connecting rod
