water in hydrolics

[Bob Rooks]

Seafoam transtune is SPECIFICALLY made to dewater a sump.. it grabs the water in soloution ( not suspension / emulsion ) ad it.. let it mix.. change the oil.. safe for trans oils and hyd oils..

Thanks for the help. Changed out the hyd twice and it went from a butter churn. To a gravy (turkey color). System seems to be faster. Is there a heavier hyd/trans fluid that would be better then THF or AW-32?

The "gravy" color of your hydraulic fluid means the system is still dirty. That's why a kerosene flush is so very often recommended. Clean hydraulic fluid should be so clear, that it's difficult to even see on the dipstick.

AW32 has the viscosity equivalency similar to that of a 10W engine oil. Then the higher the number, the thicker the fluid. AW46 and 68 are in the 20W range, AW100 moves into 30W territory, et cetera.

But many folks in cold country have found that using anything thicker than AW32 requires too much warm up time before the steering and hydraulic work. I say this, because many universal (THF) fluids are very often in 30W territory.

So, is there a kerosene flush that I can look for? I read the seafoam and yes it should work, but I want to say old school unless I need to get creative.

Questions: changed out for 3rd time.
1. how long before I change it weeks, day, a month, 10 tractor hours?
2. What color should the 3rd change be?

Yup. Plain old kerosene from the pump. Diesel fuel will work too - but kero give a better flush, and drains out better than diesel.

1. how long before I change it weeks, day, a month, 10 tractor hours?
2. What color should the 3rd change be?

Drain the turkey gravy out now. Flush immediately. I use a cheese cloth to strain what comes out. That way I can evaluate the big chunks, and the kero can be re-used for subsequent flushing. To maximize the cleansing, overfill the sump with kero - start the tractor - then exercise all the hydraulics, including steering. You want to flush the sump, the pump,. cylinders, hoses, screens, valves, everything.

Like I said before; after an effective flush, the hydraulic fluid should be so clear that you have a hard time even seeing it on the dipstick.

If I were flushin with kero. I'd dump in a couple bottles of 90% alchhol so at least it will grab some water in soloution.

So I would like to thank all of the sound bits on this problem. I drained and added new hyd. Then I put some sea foam. There is two kinds one that works with the hydrolics and diff. I used that one. Added it. Everything has been working better. Then I was in town and saw a guy working on a Korean Tractor. He was putting diesel into his hyd. He said that he uses it to clean out the system. I tried it (kiro $8.00, Dies $2.30) Used it to flush and everything runs really fast. I went and drove around, played FEL. Then I flushed this and added more and it is looking clear. I will flush it and put in hyd after opening every valve and cleaning out the diesel.

The best part "well sort of" some one has been driving up to tanks and filling up under the moon light around the area. So I am more then happy to help them by giving them a new tank located out by the road filled with my new fuel.

 

[mffarmall]

Changed out the diesel and got a good lift out of it. Might look at keeping it in? Could the hyp pump burn out with such a light mix?

 

[Soundguy]

Thinner oil than recomended.. ( real thin if it is diesel ) could possibly cause cavitation.. which could eat the pump. IMHO.. I'd run the reccomended weight / type of oil based on temperature and manufacturers specs.

It's not like the 60 year old tractors where the manufacturer said to add a quart of kerosene to the 90w hyd/gear/tranny oil to thin it during winter.. etc.
