The 8N is definitely in better shape overall. From research of past topics I assumed condensation was the issue. Maybe the cracks allow more air, hense more moisture into the chamber to condense?
If the water and oil do visibly separate in a bucket when stored, would it be reasonable to try to reuse the oil? Or would there be enough water left in the oil to just give me a head start on needing to change it again?
Doctor, I answered these two questions partially before although I see that I used the word oil instead of water in one place. Please read this carefully.
Generally speaking water doesn't mix well with older type oils. The oil will rise above the oil. Newer oils with additives tend to absorb the moisture and hold onto it so that it is NOT LIKELY TO SEPARATE.
The key here is WHAT OIL IS IN THERE???? old type gear oil will not hold water and will tend to separate. In recent years old tractor owners wish to use the best and most expensive so it has become common to use UTF or universal tractor fluid, despite the fact that the old tractors have neither clutch packs nor wet brakes. The additives in UT
F tend to hold moisture so the oil becomes foamy, and the moisture is not likely to separate. If it separates it is older oil, most likely 80W90 gear oil, And if it separates, it is separated and you could conceivably reuse it.
I would use cheap hydraulic oil and just periodically drain the water off the bottom. Trying to reuse foamy UTF would be bad because the foam indicates water which is not a good lubricant.
