806 Moisture in Hydraulic/Tansmission fluid

I"ve always had this problem and never found an answer to preventing it.

I"ll change the fluid in the hydraulics/transmission and before winter hits I have a milky fluid that gets ice crystals that plug the filter in the winter.

Is there anyway to keep that condensation out of there?

Appreciate the help as always,

Bob

I would doubt you have that much condensation. I would look for a water leak. Did you power wash it or leave it out in the rain?

Use the tractor more often for longer periods of time or use a better oil. We have been using a tractor hydraulic oil from the local distributor for years with no problem. In an 806 ,856,1466,574 and 4166.

Have never tried this, but I wonder if tractor trans oil could be reclaimed by heating the oil in an open top barrel over time to about 250 degrees to boil out the water. I have the same trouble with older tractors that don't get used much, but sit under a lean-to on south side of the barn. Has anyone tried this since oil is getting higher in price?

You're right about the higher price and this 806 takes a lot of it for one change.

i put a coffee can full of milky stuff on the top of the wood stove. after the sizzling stopped, took it off and let it cool. looked like new stuff after that. don't know what the heat might do to the additives...

Had the same problem with a 966. We flushed the system twice and later had the dealer do it when we had the clutch replaced. Tractor was shedded but the problem kept coming back. We always used hy-tran. Finally traded the tractor off, never did figure ot out.

Most of the water will settle out if you just let the oil set in black containers in the sun for a few weeks in hot weather. You still have to throw some away, though. Perhaps one could expose it to a long period of below-freezing weather and then strain it.

all i can say is that you do not run the tractor for long enough periods of time to really get it up to operating temp. to cook the moisture out . You run it just long enough to get it warmed up do what ya have to do the ya park it . all that cast iron is warm and the air is cool and it acts like a toilet tank in the house on a hot day ya flush it and the warm water goes down the drain and the cold water come back into the tank and the out side sweats on a tractor it works the other way . also when the weather warms up and the tractor is cold they not only sweat on the outside but also on the inside and it will make LOTS of water on the inside . Change filters more often work the tractor harder and longer , IF the tractor sets for long periods of times before ya start the tractor try loosing all the drain plugs and let the water that is on the bottom drip out . Yea i know it is a pain in the Arres but it does work and it does help . I have drained out a couple gallon out of my 806 over the winter from setting as normally the 806 and the 1066 does not get used when it gets cold out . The cold weather tractor is the 706 gasser . Unless your keeping them in a heated shop at a constant temp they make water unless your working them hard like plowing discing chopping , chore work does not burn the water out.

After being a mechanic in a case IH delership for 25 years I saw this problem weekly on customers tractors as well as my own. The problem is that hytran keeps water in suspension, it doesnt seperate. Now that I have my own shop I got away from hytan and use a universal hyd-trans oil and I simply crack the drain plugs after the tractors have been parked a week or two and drain the water off.
