• If it exceeds the specification, replace the piston, piston pin, snap ring and connecting rod.

Connecting rod large end standard side clearance

0.14—0.36 mm {0.006—0.014 in}

Connecting rod large end maximum side clearance

0.435 mm {0.0171 in}

3.Remove the connecting rod cap.

4.Position plastigauge atop the journals in the axial direction.

5.Install the connecting rod bearing and connecting rod cap. (See CYLINDER BLOCK ASSEMBLY (I).)

6.Remove the connecting rod cap.

7.Measure the connecting rod oil clearance.

• If it exceeds the specification, replace the connecting rod bearing or grind the crank pin and use oversize bearings so that the specified clearance is obtained.
