[AT] Spam> Hydraulic Oil Ffoaming

[charlie hill]

Dennis,  Bo's advice is sound but one thing you can
look for.  If it sits completely unused until you get back to it,
before you start it up take the drain plug out.  The fluid will
have had time to completely settle out and if there is water
in the system it will come pouring out first, followed by the oil.
If you drain it like that and let some of the oil out, then put the
plug back in, top it off and try it and see if the problems is gone
or improved.

I don't have a lot of MF experience but I've had water get into the
hydraulics on my Allis tractors and was able to get it out using this 
method.
I agree with Bo, changing it out is good advice.  Either way drain it before
you ever start it up and the water and crud should come out first.

Subject: [AT] Spam> Hydraulic Oil Ffoaming

I have a MF35 Deluxe on Oklahoma. 3 point used to work fine a year ago, but 
get weak and slow after 2 hours of use. Now it works for 10 to 15 minutes 
and then the oil foams and lift stops working until after it sets and the 
foam goes away.
I have checked the screen and it seems to be OK by feeling around it, but 
have not taken it out. Feels like it is wired in place. Oil level is fine.
I wonder if there is condensation in the oil causing the foaming.
I also wonder if the relief valve is dumping oil and that is causing 
foaming.
I have not had enough time in Oklahoma to spend a lot of time trying various 
things. Next time there I plan to completely drain the system and reseal 
covers that are leaking.

Any thoughts on why this is foaming?

Thanks
Dennis
