 Thank you Jacques, for reminding me about his article.  The same article by Graham is on our website in the Tutorials section.    The one on our website is a little different in that the pictures are larger and there are a few graphs added to the end.  Here's a link to it: Repairing Mechanical Filters From An R-390A.  It's from 9-3-2007.
