BME011011010604

1.• Measure each piston pin hole diameter in X and Y directions at the four points (A, B, C, and D) as shown.

Standard diameter

  29.997-30.007 mm {1.1810-1.1813 in}

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

Standard diameter

  30.014-30.030 mm {1.1817-1.1822 in}

3. Measure each piston pin diameter in X and Y directions at the four points (A, B, C, and D) as shown.

Standard diameter

  29.994-30.000 mm {1.1809-1.1811 in}

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

Standard clearance

  - 0.003-0.013 mm {-0.00011-0.00051 in}

5. Calculate the clearance between connecting rod small end and piston pin. Replace the connecting rod or piston pin if necessary.

Standard clearance

  0.014-0.036 mm {0.00056-0.00141 in}
