Dear John , Thanks for your help! another pc400-7 : KMTPC192A02070395 coud you also help me with this one? I really appreciateThe first number doesn't show up for a US designated machine. PC400-7 machines were built from 2004 until 2007. There are probably earlier ones as Komatsu usually puts out machines in Asia and Europe before they land in North America.
The PC200-7 serial numbers in North America start at 50047 so the same issue applies with this machine as well. I show years built from 2002 to 2006 for North American machines.
