  Standard Grade No. 0: 21.989 - 21.995 mm (0.8657 - 0.8659 in) 

  Grade No. 1: 21.995 - 22.001 mm (0.8659 - 0.8662 in) 

Connecting Rod Bushing Oil Clearance (Small End)

(Connecting rod small end oil clearance) = (Inner diameter of connecting rod small end) - (Outer diameter of piston pin)

Standard: 0.005 - 0.017 mm (0.0002 - 0.0007 in) 

Limit: 0.030 mm (0.0012 in) 

• If the measured value exceeds the standard, replace the connecting rod assembly and/or piston and piston pin assembly.
• If replacing the piston and piston pin assembly, use the Table for Selective Fitting for Piston to select the piston corresponding to the applicable bore grade of the cylinder block to be used. Follow the "PISTON-TO-CYLINDER BORE CLEARANCE " procedure.
