The connecting rod and the connecting rod cap should have an etched number on the side.
The number should match the cylinder number. Mark the connecting rod and the connecting
rod cap, if necessary.
Note: Do not stamp the connecting rod assembly. Stamping or punching the connecting rod
assembly could cause the connecting rod to fracture.
5. Put a temporary identification mark on the top of the piston in order to indicate the cylinder
number that is shown on the connecting rod. Put the temporary mark on the same side as the
mark that is on the connecting rods in order to ensure correct assembly of the piston and the
connecting rod.
Note: Do not etch the top surface of the piston. Do not allow scratches or stamped markings
in the top surface of the piston.
