Let the tractor sit for a few days in the location where you plan to work on it. Before starting it drain the water from all three plugs, one at a time. We all know that oil floats on water. Pay close attention to how much water comes out into your drain pan. The water will come out first and then it will transition into milky hydraulic oil. Replace each plug when the water gets all. Then I suppose it would be best to get the milky hydraulic oil up to operating temperature and then drain all of the remaining oil. Replace the oil to the correct operating level.
If you could determine which line is the return line from the loader valve to the transmission, it would seem like you could capture the contaminated oil after it is cycled through the cylinders and returned through the valve before it gets to the transmission. Keep the transmission at least close to the correct operating level as the contaminated oil is captured in a container.
I would guess this would get about two thirds of the milky oil out, with the least amount of dismantling the tractor. Keep in mind that a year from now,
the new oil will have just as much water as the current oil contains. Use the
same procedure each year and keep a written record of the water quanity.
I realize there is some sludge in the transmission and contaminated oil left in
cylinders, but more water will appear each year. I do not consider totally dismantling the transmission, rear axle, and loader hydraulics routine yearly maintenance.
I would like to hear Ford/New Hollands answer to this issue. I think they just don't care. In fact I am sure of it.
Ever notice how the side cutting edges on the bucket are welded on with the bevel towards the outside? I told the engineers during a factory tour about this. They said my bucket was built wrong. Go look at any FNH bucket, I bet it was also built wrong also. A proper cutting edge cuts a path wider than everything behind it. Simple engineering learned in the sandbox with METAL
