You may find this old thread useful: "1929 640 Rear Pinion Seal"

There's an oil slinger on the back of the seal which should deflect the majority of oil. It seems that the felt seal is the only real seal on the Pinion but it should not be exposed to excessive volumes of oil when everything is operating normally.
