Default RE: New (to me) internet myth


ORIGINAL: Antique

A customer told me today he heard that the A stamped on top of a Sachs piston means top of the line, a D on top means industrial grade...What a CROCK...Maybe we should start a thread with all these internet MYTHS listed for newbies..We ALL know the old timers don't perpetuate these things, don't we ?
I didn't read the whole thread, but you are correct it is a CROCK. "A" or other letter stamped on a part generally means revision A,B...or whatever revision they are on.
All of the car manufacturers do this that I am aware of, any number of other industries do this as well, including the printing press manufacturer I used to work for. It is an extremely common SOP. Whatever the Letter scheme denotes on a Sachs piston, I don't know but I am sure it denotes differences in the parts that you can't just look at and see easily.
