[AT] rod bearings

[Grant Brians]

This practice has been standard in many if not most internal auto parts and
machinery parts manufacturing as a means of making sure that inventory and
quality control are easier to maintain. Check out many of your computer
semiconductor parts and the printed dates and/or lot codes on them. Today
the packages are likely to have a bar code on them and that is the modern
equivalent with the computerization of many of the stamping practices of
old. Having them stamped with the manufacturing date also does help the
person today though because then there is an indication as to the materials
used and the likely timeframe of whether the engine is original or had been
rebuilt between manufacture date and now.

I've noticed in quite a few engines I've torn down that the rod bearings
have what appears to be the manufacturing date stamped on them. Anybody else
noticed this and know why?
