Don't remember ever seeing any specific info on lubing governor -- or working on them at all for that matter. There was an article on waterproofing and one or two about engagement speeds and that the speed point could be changed by the adjust screw under the tar. IIRC, Packard cautioned their mechanics it was not a good idea to mess with the screw because it was easy to get it totally out of whack and suggested replacing with a governor from another model with a different calibration if the operator was unhappy. Believe governor was mostly treated as a remove and replace item if there were issues.

I would think a minute drop of oil on the pivots for weights would be sufficient. Just make sure nothing excessive can run down and get on the contacts. Also a drop on the shaft but that one in your photo looks like the trans oil may be seeping or being forced in and coating things -- either that or the oil vapors could be condensing inside. I don't remember if the OD has a separate vent or if it shares with trans but would wonder how well the vent was working.

If you have the standard OD cable with 1/4-28 threads on the shaft Yesterdays Radio makes the correct repro knob in beige to match the others in the car. Am sure price would be considerably more than a comparable cabinet knob though. McMaster has some larger threaded knobs if you don't find something locally.
