  2. Measure the piston pin-to-piston clearance.

    Piston pin-to-piston clearance: 

    0.004 ~ 0.013 mm (0.00015 ~ 0.00051 in.)

  3. Check the difference between the piston pin diameter and the connecting rod small end diameter.

    Piston pin-to-connecting rod interference: 

    0.005 ~ 0.019 mm (0.00019 ~ 0.00074 in.)
