i have a farmall 400 rear end that i am draining because it froze this winter. replacing with new. i want to place this oil minus h20 in my twin vertical upright mixer. 30 gallon. how can i remove moisture from used oil ?
 
Sometimes you can park it in a warm climate for a long time. Then one nite when it's
zero sit it outside. Next day be for it thaws dump out the oil...
 
There are a few ways to do that. What the other guy says works but you have to be careful not to shake it much when you take it out side to freeze up. Or you can heat it up and let it heat but not boil which will slowly remove the water.
 
I once drained one into 5 gallon buckets and covered them so that contraband material would not be in the mix as well. After the water settled out I tried to dip the good oil off the top. It almost immediately started to mix back together so I stopped. I forgot about that project for several weeks then happened to stumble over them later. The water had turned into a large ice cube in the bottoms of the buckets. You could pour it off the ice. As it turned out I no longer needed it so it went to settle the dust in the driveway. I wouldn't have been afraid to use it in something for lubrication though had I needed it. gm
 
Let the tractor sit for several days. The oil will float on top of the water,so pull the plug, let the wter run out and when oil starts coming stick the plug back in. I have drained several H's this way. Oil always floats on top of water.
 
If your 400 has a TA the oil in rear end would be Hy-Trans which is a hydraulic oil. Hy- Trans keeps the water in suspension and needs to go through a filtering system to get all the water out.
 
I have a small bucket in my freezer right now with gear lube out of my DC3 Case rear end. I have done it before, the water freezes and you can pour out the petroleum product. Also I have used an old deep fryer to boil the water out.
 
By replacing it and sending the old contaminated out to someone that re-manufactures oil. I forget what they call it exactly, but there are companies that do it and then resell it. As a kid I used to work at a national chain auto parts store that sold such oil wearing our store name's label for about half price of other oils. Was it any good? I don't know why not if it's filtered and refined as it should be. Did I or would I ever use it? Haven't yet and I'm closer to death of old age than I am birth.

Put 2 spigots on a bucket and let the oil sit for a while, it will seperate out. One spigot on the bottom and the second one up 4 inches or so. When you drain the bottom spigot, you will get clear water, then the milky oil, then clear oil. At that point, the upper spigot is safe to drain from and use.

When Im draining from the bottom spigot, I dump the water. When the milky oil comes out, I save that and pour it back in the top when I done getting the good stuff. Its good oil, just needs more time to seperate out from the water.

Several times a year I drain out the water, I welded a pipe nipple on my drain plug and put a ball valve on. I drain out a half gallon or gallon and pour it in the pail. I replace the oil from the tractor with good oil I took out of the pail a few minutes earlier (so it done mix together before I pull out the good stuff).

If you heat the contaminated oil to about 230 degrees the water will come out of it pretty quickly. The oil won't boil. Did you drain off the free water when it thawed out? It doesn't take much water to stick the bull gears. I've never had oil saturated with water freeze and I only drain off the free water, not the good oil and do not have problems.
 
I use a laundry soap container on it's side. It already has a built in spout. Let oil set for a few months and solid particles will settle out.
