Reclaiming milky hyd fluid

I have a hytran equivalent in my 300u. The hydraulics and trans get milky quite fast. I thought I would try letting the milky fluid sit in a container, drain the moisture off the bottom, filtering the remaining fluid and using it again. The fluid has sat about 3 weeks, it has been quite cold 0 to -20 degrees, but nothing has separated. It is as milky on top as what comes out the bottom. Am I doing something wrong or will my experiment just not work? Do the temps make a difference? Thank you for reading and any thoughts.

Year ago I designed and built an oil reclaim system for an ammonia refrigeration plant. It worked very well and Texaco said the oil met new specs when tested. You need a vessel,(small hot water tank) small oil pump with motor, cheap air compressor, and some spin on oil filters with mounting hardware and a bunch of pipe fittings.

The compressor was used to pull a vacuum on the system (hook up the intake to the tank) which lowers the boiling point. Set the thermostat on the hot water tank to 140-160 so the oil does not overheat and degrade or form carbon. The pump circulates the oil through the tank and filters. This system was used to reclaim about a barrel a week of contaminated oil which would otherwise be lost. A fair bit of work to set it up for a one shot deal but you do not have the marital problem with oil on the kitchen stove in her best pots.

Karl,

I need a vacuum pump for another application. That would be to lift oil 15ft into a pressure vessel. Do you have any data on the inches of mercury an air compressor can develop. I have never seen negative pressure flow graphs on air compressors.

I may eventually spring for a properly sized vacuum pump.

Wardner,
Air compressors can ary dramatically in terms of vacuum available. aIt all has to do with the type of valving, state of the piston rings/diaphram, and compression ratio. Some pumps will not make more than 120psi even dead headed, while others will make twice that. Designs are not comparable.
Refrigeration compressors are much better at vacuum. If a used compressor is available, they will pull at least 20"HG. Garst corporation makes inexpensive vaccuum pumps as well.
In all cases it is necessary to keep the transfer oil out of the pump to avoid sevier dammage.
Why not use a small positive displacement pump at the lower end of the system.
Little Giant makes pumps with oil compatibility for $50.00 and up. A power steering pump from almost any vehicle will also do it.
Just random ideas on the topic. JimN

Why would you waste the time trying to seperate it. The best thing to do would be to buy some inexpensive oil fill the system, run it with out working it to flush all you can out. It make take 2 or three times, then fill it with a quality oil. Its not worth the chance of moisture in a hydraulic system for the cost of oil and filters. In the long run, water can and will be detrimental to a hyd system

Hydraulic oil absorbs water. Be careful trying to re-use it. I"m in the marine industry and any hydraulic oil that comes in contact with water gets disposed of and replaced with new. In the tractor, a little probably won"t hurt too much, but I"d replace it when it get"s bad enough.

Jimer: Gary about 4 posts before you was the guy that tried evaporating the water off with heat. Read his post, he's still having problems with the 460. Talk to Gary, he'll tell you if it works.

About 8 months ago, I went through the same problem. I bought a 460 U with contaminated fluid and I used Jay Walts idea but did it full scale. I put new fluid in it and it got milky so I hated to throw it away. As these find fellows have said, it will not seperate by itself, but I used a 5 gallon turkey frier and was successful in boiling off the water. Once i had the setup runnjing it wasn;t to much trouble as I was working out in the garage anyway. When the batch is done pour it through a t shirt in a big funnel into a metal can while it is hot. Then its ready to use again . I did 20 gallons like that. Sure it took some fuel but this old world needs stuff like that recycled. Be sure you watch it, as you can cook it passed where the water is out.

Heating it up outside in a double boiler (water in the bottom pan, oil in the top) will drive out the water. A outdoor proposition and it must be watched all the time so the boiling water is not boiled away allowing high temps and fire danger. The bigger the container, the bigger the heat source must be to make it work. An element from a hot water heater designed for 220 running on 110 might do the trick directly. An insulated bucket would be the ticket then. Watching it is the hard part. Be careful!!! JimN

I did a reasonably good job of separating some one time. Stored it in unheated building. The water froze at 20 deg, perhaps before then. Pour off the oil. That will eliminate the majority of the water.

It will never separate sitting in a bucket or tractor. It has emulsifiers in it that bind the water to the additives.

I think it was last spring that another owner of a 300U successfully cleaned his tractor fluid. He reported on the process with alot of posts and pictures. I have forgotten his name already and he no longer posts here as he sold the tractor shortly thereafter. It shouldn't take long to find his post in the archives.

He used a hotplate and saucepan to drive off the water. I would just buy 10 gals of new oil and convert the old oil into BTUs in a potbelly stove.

Sounds like you are talking about Jay Walt.

Doing that can be pretty hard to do. You might try heating it up a good bit to sort of boil off the water but you have to be careful not to get it to hot or you will burn the oil which is just as bad as having water in it

Jimer, Hy-Tran has an additive to suspend water. That makes it hard for it to seperate and settle.
