Connecting Rod Bushing Oil Clearance (Small End)

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

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

Limit: 0.030 mm (0.0012 in)

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 "HOW TO SELECT PISTON AND BEARING ".
If replacing connecting rod assembly, follow the "CONNECTING ROD BEARING OIL CLEARANCE" procedure to select the connecting rod bearing.
