Connecting Rod Bushing Oil Clearance

(Connecting rod bushing oil clearance) = (Connecting rod bushing inner diameter) - (Piston pin outer diameter)

Standard and limit: Refer to "CYLINDER BLOCK ".

If the calculated value exceeds the limit, replace connecting rod assembly and/or piston and piston pin assembly.
If replacing piston and piston pin assembly, refer to "DESCRIPTION ".
If replacing connecting rod assembly, refer to "CONNECTING ROD BEARING " to select the connecting rod bearing.
