Cost? :) what's cheaper.. a pail of oil..or the pump plus downtime.

My big fords hold somthing like 13g of hydro oil.. and it usually comes out darn good looking.. but it's cheape rthan a 1000$ pump, plus flusing all the lines and cleaning all the valves AND then changing the oil and filter. :)

I agree.

After my knee-jerk panic that my pump was dead, the cost of the extra fluid is minimal.

What do you recommend for the oil/diesel mix?

When I flush a sump that has been wet or dirty, i always add in some trans tune/seafoam.. or some 90% isopropyl alcohol, plus oil, plus some diesel, then circulate it a bit, then dump.. the seafoam or alc, grabs any free water and holds it in soloution.. the diesel thins it all out and makes it so any debri or suspended particles will run out fast vs settling. the oil is there for some lube and some viscosity and to up the vapor pressure to prevent cavitation that straight diesel would likely cause.

if a sump holds say.. 5g normally.. I usually short it and dump in say.. 3 or a hair more.. just enough to get things going.. and I usually do 50/50 oil/diesel mix.

WOW Soundguy..., wish you were closer..!! I'd gladly bring you a barrell to fill when you service your tractors... That stuff burns great in my waste oil furnace..!!

My neighbor is a stickler for changing his hydraulics in his Cat D4 and JD 410 Hoe. That's good for a 55 gallon drum a year, plus engine oil services.

Between him, a couple buddies, and my oil, I stay just pretty toasty in the shop all winter.

So if some of you in the northern regions are worried what to do with your used oils... Guys like me will gladly take it..!! Post it on Craigslist, etc. I usually collect a year ahead of time. Gives the water time to settle out. I've got ball valves on my storage tanks, and crack them in late September, to drain any water off...

yep.. between my 2 laqrge tractors.. it's 26g of just hydro oil.. then another 5.5g of crankcase oil. add in my other machines that have about 6.5g of total oil in them each... and it adds up!

Change your oil, dump in a couple bottles of isopropyl. I would clean the suction strainer too.

Hmm, so it was icing up. Nah, couldn't have been icing up! Well at least that was what was suggested. Should have put a gauge on it. ;)

Why not save some of that hyd fluid, and let it sit up for a couple of days in a mason jar. You might want to send a sample in for testing just to be sure about things.

I don't know the cost for testing, but someone on probably does.

Freezing hyd fluid.

Glycent 46 Hydraulic Fluid has a freezing point of -57 degrees Celsius, which is -70.6 F

It's happened to me more than once. After thawing out, I would work it until warm and drain the fluid. Replaced with lower cost fluid and worked it long enough to warm again and drain. Refilled with proper fluid and no more problems. I do store it in a barn now, so that helps. Seems fairly common up north, on older tractors especially.
since water in the fluid usually turns it milky and seems less likely to freeze, I assume it is from the cold/warm/cold cycles causing condesation to drip off the interior, and the droplets sink through the fluid without mixing. Then the cold days freeze it in the bottom before having a chance to mix with the fluid. I've had it happen and then after thawing it worked fine for the rest of the winter even after much colder temps. Cold/warm/cold cylcle, that's my theory. If it was a few degrees warmer before you started it, the water would have been thawed again and blended into the fluid for good.

I also had this happen to me on a log splitter.Left a friend use it & he wanted to do me a favor and pressure wash it down,well he got to close to the vented fill cap and must have really been putting the water to it because the hyd.tank was full to the top with water. I found this out when i needed to use it was in the single digets i couldnt even pull the rope to start it.Got to looken yep froze up.It had a 2" thick slab of ice in the bottom of the tank that i found when i got the oil out with a ladle (lots of dipping)nothing would come out the bottom outlet pipe.Heated the tank got the water out drained all the lines,pump,valve,cylinder etc.....Filled back up ran splitter repeated the draining process $90.00 later in fluid it worked fine.(The tank had ice in it,the pump,lines,filter,cylinder,valve had a milky thick molassis like fluid.)I had to heat eveything to get it to drain.

Soundguy,
What do you use to catch the oil when you do your change? If I remember right, the 2240 I bought holds 16g.
