Tim: The creamy, tan color of your differential oil occurs from water being suspended in the oil. The New Performance Major was notorious for leaking water into the differential from two places. One being the dipstick located down near your left foot and the other being the standard
fill plug located behind the seat at the upper/rear portion of the differential housing. This cap was fitted with a small hole (vent) and when these tractors sit outside water will find it's way into the bottom of the differential.
Water will collect in the belly of the differential and also in the belly of the transmission/PTO housing further forward. If your tractor must be stored outside both drain plugs should be loosened during warm weather after the tractor has sat for a time and the water
drained. Enough water can accumulate in the belly
of these housings to freeze them and crack the cast iron. Even a small amount of water in the
forward PTO housing can freeze and prevent engaging the PTO. Water will eventually cause problems with the hydraulic pump.

Don (or anybody?) Is there anyway to filter out the water and save the hydraulic oil? No matter what I do I seem to pick up water during the season and have to replace the oil every fall. I need to remove the water to blow snow in the winter and if I don't I risk freezing the hydraulics. I put a heater plug under the tractor to thaw the water but I'd like to be able to get the water out of the oil if possible.

Living in Ontario, Canada I have experienced hydraulic fliud freeze up due to water in the fluid.

The solution I have found is to pour a bottle of gas line anti-freeze in the oil if feezing occours. This will absob the water and evaporate quite quickly.

I have done this for 2 seasons now with no effects on seals or rubber components.

Rus: In a word... No. I am not aware of any method. Prevention is the cure. After the tractor has sat for a period of time some water will separate out and settle to the drain plug area but once the water is churned and mixed with the oil most of it will remain suspended.

Are you absolutely sure there is water in the oil.
You can drain the oil out, flush the casing and crank the tractor back up. The new oil will be creamy again in less than 5 minutes. The hydraulic system just naturally mixes minut air bubbles in the oil. Another inherant situation with the older fords and fordsons
Catch a glass jar of the oil and let it set over night,it probably will not have water separated out . I have repaired many lift systems for folks who didn't believe this. However after letting the oil set 2-3 days, there would not be any water present, and the oil would still be milky. The new oil would be milky in the tractor too, even though the tractor had been in the shop and no rain or condensation too be found.If you find no water present and the milky still bothers you, you can use the new synthetic base hydraulic fluid. it doesn't foam like the old petro base.
Good luck,
JJ
