Once upon a time I had a copy of GM's general machinery vibration specification, circa 1996 (?). It was one section in a much larger document. It had some pretty typical limits for vibration measured in velocity, with several bands based on operating speed, and 1 or 2 acceleration overalls. Does anyone know where a copy could be downloaded?

Dan,

I have a version dated 9/22/04. E-mail me for a zipfile.
