Assemble connecting rod and piston with the piston pin.
Check that the classification of each cylinder and piston diameter as well as any numbering of the connecting rod correspond.
Install the piston pin's two lock rings. Check that the lock rings are positioned correctly in the piston. The opening shall be positioned in the vertical line.
