grinchsr 599 #1 Posted June 17, 2014 I have a M12 SPEC - 471527 SERIAL - 2003004533 How can I find the build year of the motor? Share this post Link to post Share on other sites
64s 83 #2 Posted June 17, 2014 From what I've been told, add 70 to the first two digits of the serial number to find the year, and the next thrre digits is the day built. So yours should be a 1990 built on the 30th day. Share this post Link to post Share on other sites
