Standard piston pin bore diameter

33.997—34.007 mm {1.3384—1.3388 in}

2. Measure each connecting rod small end inner diameter in the X and Y directions as shown in the figure.

Standard piston pin diameter

33.994—34.000 mm {1.3384—1.3385 in}

4. Calculate the piston pin-to-piston pin bore clearance. Replace the piston and/or piston pin if necessary.

Standard piston pin-to-piston pin bore clearance

–0.003—0.013 mm {–0.0001—0.0005 in}

5. Calculate the connecting rod small end-to-piston pin clearance. Replace the connecting rod or piston pin.

Standard connecting rod small end-to-piston pin clearance

0.012—0.039 mm {0.00048—0.0015 in}
