Connecting Rod Bushing Oil Clearance (Small End)
WARNING: This page is about a different variant/trim than selected.
Inner Diameter of Connecting Rod (Small End)
- Measure inner diameter of bushing. Refer to "STANDARD AND LIMIT "
Outer Diameter of Piston Pin
- Measure outer diameter of piston pin. Refer to "STANDARD AND LIMIT ".
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 : 58.944 - 58.968 mm (2.3206 - 2.3216 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 "Piston Selection Table" to select the piston corresponding to the applicable bore grade of the cylinder block to be used. Refer to "HOW TO SELECT PISTON AND BEARING ".
