[tthopskin@yahoo.ca]

a question guys ..i think i mite have ice in my hydraulics .question is there anything out there that wont heart the seals in the system 580 c case backhoe .and will get rid of the ice temp here anywhere around -15 to -35 cel thats -3 to -30 fer :ashamed:

If your fluid is saturated with water and emulsified, you need to drain and replace. Then cover the machine if left outside.

Get it into a heated place. Let it thaw out. Drain the hydraulic oil and let it sit. Perhaps the water will separate? Or use some new oil. It will happen again if the machine sits without getting the oil hot for longer periods of time. Getting it hot regularly for longer periods of time will get rid of the water. Most yellow equipment spend's it's life exposed to the elements.

Don't know your situation, but in my case with my front end loader, it's not ice in the hydraulic oil, it's the spool valve spring that freezes.
When I re-discover it, it's usually too cold to take it apart an get the moisture out, so I just heat it while the tractors warming, and when it's warm out, it's no problem so why fix it?! (The leaky roof syndrome)

Being the impatient type, it's probably good that it forces me to let the tractor warm up while I go get a hairdryer (well, I use to use a hairdryer), but now I am too impatient so I just use a propane torch.

If the problem clears up when warm, I would recommend to remove the cans on the bottom of the valve and clean , lube and make sure the weep hole is at the bottom.

 

[tthopskin@yahoo.ca]

that sounds like a good thing to do i am going to change the filter too,,thanks again JJ

 

[tthopskin@yahoo.ca]

JJ you were right . in one of my post you said i spun a bearing .i did the #4 cylinder . have not got right into it yet .we loosened the rod cap the piston moved up and down .tightened the cap snuff it up again . so i will try to let you know later how we made out ..new crank or just bearings ..wishful thinking . and a new head gasket to Preston in oil ..

Just an FYI. If you had water emulsified into the hydraulic fluid and it was cold enough to freeze and turn into ice you probably crushed the hydraulic filter when you stated the backhoe up. Now I am not referring to a spin on type of filter because that one would have probably leaked externally do to the back pressure and you would have seen that. I am referring to one of the cartridge type that is enclosed in a heavy steel cylinder with the center bolt. Last year during the late winter early spring, just before sap season, on my relatives JD 2940 I replaced the hydraulic fluid twice and both times the filter was crushed due to ice in the hydraulic fluid. It has hydraulic steering and the crushed filter first starts to effect the steering. It is probably crushed again this year because the tractor lives in the open. That's all I have. Later.

If water is a constant problem, then a plastic sheet or taarp should be used.

Much cheaper than new filters and fluid changes, plus other damage from ice bursting other hyd components.

My number one question would be how is the water getting into the closed hydraulic system to begin with?
If you were to correct that situation then all would be hunky-dory again.

 

[Egon]

Condensation. The unit warms up but not enough to get rid of the condensation.

The hyd system might not be as closed as you think.

Just ask all the hundreds of people that that has had water in the hyd tank.

Another possibility is sump breather is plugged so heated condensation has NO OUTLET to escape.
