3. Ensure that the connecting rod (1) and the cap (4) are correctly marked to the cylinder.

   Note: Matched identification marks (X) on the connecting rod and the cap ensure that the pistons and connecting rods are installed into the correct cylinder in the cylinder block.

4. Remove the nuts (5) from the connecting rod bolts (2).

5. Remove the cap (4) with the bearing shell (3).

   Note: Use tape or rubber tubing on connecting rod bolts (2) to protect the crankshaft journals. The sharp edges of the connecting rod bolts could damage the crankshaft journals.

6. Push the piston and connecting rod (1) away from the crankshaft until the piston rings are out of the cylinder bore. Remove the piston and connecting rod from the cylinder block.

   Note: Make an identification mark underneath the piston on the pin boss in order to identify the position on the piston for installation. Always mark the front pin boss.

7. Remove the connecting rod bearings (3) from connecting rod (1) and cap (4).

8. Keep the matched connecting rod (1) and cap (4) together.

9. Repeat steps 1 through 8 in order to remove the remaining pistons and connecting rods.
