Gene, you know that crankcases, differentials and transmissions have been vented on cars and trucks for many years. Expansion of gases with heat and compression with cold is a very basic fact of physics. Before engineers and designers started designing purpose made vents in, the air went in and out through places like around PTO shift levers 3 pt lift arms and the like. If the only places available were axle, input shaft, and PTO seals, well that is where the air went in and out. Vents are not there for decoration or in order to have something extra to charge for. They are necessary to prolong the life of seals. to reduce the suction of dust into the seals. Air is going to move in and out, and moisture with it. Moisture will condense on a cold surface. You cannot tell me that you have never seen moisture condensed on the cast iron of a tractor on a cold morning or even mid-afternoon when a humid air front comes through. Well if it condensing on the outside, it is condensing on the inside at the same time. How would you separate the water vapor from the air?
