Ross Miller's treatise sure does bring the factory shop manual procedure (which was pretty comprehensive, itself) up to date for units that have seen decades of use (or neglect) - a great help to anyone wanting to rebuild the BTV. The images that he provided show several things that I've encountered, but words alone could never describe. His approach includes a few new things that I'll incorporate in future overhauls, as I intend to retain the BTV.

However, I'm also confused about the original compensator port spring being made of stainless. Of the three units that I have had completely apart for rebuild of at least the hydraulic sections, none of them appear to have been overhauled previously (based on the difference in appearance of the replacement residual valve compared to the original). One of the compensator port springs showed some discoloration, another was starting to pit (which I want to replace, when possible), and the third had broken in two (replaced with another from a core). I'd wouldn't expect to find that with stainless wire, but there are probably as many grades of stainless as there are colors in the rainbow.
