EM-88 [QG] CYLINDER BLOCK CONNECTING ROD SIDE CLEARANCE ● Measure side clearance between connecting rod and crankshaft ● If the measured value exceeds the limit, replace the connecting PISTON AND PISTON PIN CLEARANCE ● Measure the inner diameter of piston pin bore with an inside Outer Diameter of Piston Pin ● Measure outer diameter of piston pin with a micrometer. Piston and Piston Pin Clearance (Piston pin clearance) = (Piston pin bore diameter) – (Outer diameter of piston pin) ● If clearance exceeds specification, replace either or both of piston/piston pin assembly and connecting rod ● Refer to piston selection table to replace piston/piston pin assembly, . NOTE: ● Regarding marks on piston head, refer to . Standard : 0.200 - 0.470 mm (0.0079 - 0.0185 in) Limit : 0.5 mm (0.020 in) PBIC0609E Standard : 18.993 - 18.999 mm (0.7478 - 0.7480 in) PBIC0116E Standard : 18.989 - 19.001 mm (0.7476 - 0.7481 in) PBIC0117E Standard: 0.002 - 0.006 mm (0.0001 - 0.0002 in) |
