EM-106 [YD] CYLINDER BLOCK CONNECTING ROD SIDE CLEARANCE ● Using feeler gauge, measure side clearance between connect- ● If measured value exceeds the limit, replace connecting rod and PISTON TO PISTON PIN CLEARANCE Using inside micrometer, measure piston pin hole inner diameter. Piston Pin Outer Diameter Using micrometer, measure piston pin outer diameter. Calculation of Piston to Piston Pin Clearance (Piston pin clearance) = (Piston pin hole inner diameter) − (Piston pin outer diameter) ● If clearance is exceeds specification, replace either or both piston/piston pin assembly. PISTON RING SIDE CLEARANCE ● Using feeler gauge, measure clearance between piston ring and Unit: mm (in) Standard : 0.200 - 0.350(0.0079 - 0.0138 in) Limit : 0.4 mm (0.0157 in) JEM203G Standard : 28.003 - 28.009 mm (1.1025 - 1.1027 in) PBIC0116E Standard : 27.995 - 28.000 mm (1.1022 - 1.1024 in) PBIC0117E Standard : 0.003 - 0.014 mm (0.0001 - 0.0006 in) Item Standard Limit Top ring 0.050- 0.090 (0.0020 - 0.0035) 0.2 (0.008) 2nd ring 0.050 - 0.090 (0.0020 - 0.0035) 0.1 (0.004) Oil ring 0.030 - 0.070 (0.0012 - 0.0028) — SEM024AA |
