2. Rotate the crankshaft until the piston is at the bottom center. Remove connecting rod nuts (5) from the connecting rod. Remove connecting rod cap (4).

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

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

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

5. Keep connecting rods (1) and connecting rod caps (4) together. Ensure that the identification marks are on the connecting rod and on the connecting rod cap. This will ensure that the piston is installed into the correct cylinder in the cylinder block.

6. Repeat Steps 1 through 5 for removing the remaining pistons and connecting rods.
