The production date stamped on the crankshaft sprocket (see Appendix, page 1.)

Meaning of numbers

- The first two digits indicate the production line.

- The six digits indicate the year (two digits), month, and day.

- The last five digits are the serial number of the crankshaft. The crankshaft shown on page 1 of the Annex has been made October 21, 2009.
