Oh, forgot... 6K29 is a Cummins Recon machining center code.
Wish I knew what it means, but I have no idea. During my time at mp the Cummins rep (although a nice fellow) would never directly decode those numbers for me, and the engineer I had to go through (although also a nice fellow) treated those codes as if they were proprietary information.

My stance: When a vendor is coding YOUR product, you have every right to it. So, where's the magic decoder ring?

His stance: that's their information, why should I care, all I really care about is the part number.

Try as I might to learn the logic behind the codes, it wasn't ever made available.
