I don't think 190s had final drives.

75 w 90 is quite often a synthetic blend or a full synthetic oil, is that the case here? Myself I would not use synthetics in the transmission or final drives of these old tractors with 30 or 40 year old seals still in them for fear of the oil migrating past seals into compartments where is shouldn't be. If it was a fresh rebuild with new seals I would look at it differently. And I use synthetics, but I pick my spots, and have worked in the fuel and lubricant business for 30 years.

The issues of synthetics causing seals to leak was corrected over 30 years ago.
