Typical example (U) Day code (V) Code for the connecting rod (X) Code for the Connecting rod cap (Y) Year code (Z) Code for the grade of connecting rodNote: The day code is from the first day in the year. For example, "001" will be the first day of the appropriate year.The mating surfaces of the connecting rod are produced by hydraulically fracturing the forged connecting rod. Ensure that the correct cap for the connecting rod is installed with the correct connecting rod. Ensure that the serial numbers for both components match. (2) Torque of the setscrews for the connecting rod ... 40 N m (30 lb ft)Tighten the setscrews for the connecting rod for an additional 120 degrees. The setscrews for the connecting rod (2) must be replaced after this procedure.Note: Always tighten the connecting rod cap to the connecting rod, when the assembly is out of the engine. Tighten the assembly to the following torque 20 N m (14 lb ft).
