New Holland lost hydraulics

[Bluey]

Hydraulic filters are very sensitive, if they clog the least, you can’t run things, there is not enough pressure.

You may have something contaminating the hydraulic oil and that clogged the filter and so you don’t have pressure.

What can do that?
Someone put the wrong oil in the hydraulic system or there is a leak between systems somewhere.

You know, we used to do much of our own work, but tractors didn’t cost so much and were rather simple.
Today, I would let an expert make the mistakes trying to fix it.
Or you may keep trying and eventually figure it out yourself.

HA!
Just finished fixing my tractor. And she runs like a charm and purrs like a kitten.
Okay, well she purred like a kitten for 10 feet, then hacked up a hairball and quit. BUT, that had a lot to do with hubby walking around the tractor saying,“what’s this do?” and “what’s this switch for” and I hadn’t realized while he was pointing to switches…he was switching them. Turn off your fuel filter switch and the tractor coughs up hairballs and faints. :lol: sigh
Changed out both hydraulic filters, drained the hydraulic/trans fluid and replaced it all. Yup, both filters had dirt in them. One was on the filthy side, the other was a bit gunky. Fluid drained looked like mocha latte. Nice new olive oil colored fluid in there now.
Since I was filthy as hell I went ahead and changed the oil, but neither of my filter wrenches fit the damn oil filter. Couldn’t get it off by hand, so has old filter and new oil. Damn it…will go to Carquest Tuesday when it reopens and get a new wrench in the right size. When I swap that one out I’ll change the fuel filter too. Need the bucket up for that, can’t reach it otherwise. Will also change the air filter then too…what the hell, might as well have ALL new filters.
So yay! Tractor hydraulics working and the change of fluids and filters was easy-peasey! Thanks everyone sooooo much for the help. I can now change all fluids in the tractor with no problems myself. It’s so nice having the bucket and rake working without any stuttering, jerking or hissing. Smooth and silent. :yes:

Something is still wrong … Even 15 year old hydraulic fluid drained from a backhoe was clear, till the bottom gregs of the tank. Check to make sure rain water is not getting into the system. Look at the filler caps. If the hydraulic fluid was low, there is a leak somewhere. If fluid can get out, contaimination can get into the sytem. A brown swirl in the fluid sounds like engine oil or maybe the gregs of the tank.

[MistyBlue]

Ahhh crap. Seriously? The liquid was same viscosity as the new, but it was an opaque light beige. The new fluid is a pale clear amber/yellow.

[Bluey]

Great that you could do so much.

One thing I don’t get, our oil filter wrenches are a steel loop that adjust to most sizes of filters, that you can squeeze most any place and use to gently twist the filters off.
How come yours didn’t adjust to the different sized filters?

Olive oil is the color you are supposed to have in hydraulic oil, new or old, or there is something wrong with something else somewhere.:yes:

Keep checking your hydraulic oil and if it has any more gunk showing in it, do have it repaired right, or you may really be into a big bill there.
At least ask a mechanic about what it could be.

It feels good when things work again, doesn’t it.

That sounds like water in the oil.
The shops here have the oil tested and can tell you what is going on, what the contaminant is.
That helps them to decide where to look further.

Bluey may be correct about water, Also the low fluid level may have allowed the pump to churn air into the oil. (kinda like a greasy margarita’) If the opaque fluid clears after sitting a day, it was air. If the fluid separates into layers or doesn’t clear at all, it was water. Either way you still have a problem. Contamination or a leak.

Having the old fluid tested will be definitive as the cause / problem :yes:

[JSwan]

Agreed. Sounds like water.

Don’t ask me how I know.

[MistyBlue]

Bluey, my filter wrenches are the same…a metal looped band. Except they only constrict so much. I have two different sizes and the oil filter doesn’t fit either one. The smaller one the loop doesn’t fit over it and the larger one doesn’t constrict enough to grip the filter. Mine only constrict a small amount. Probably so I have to keep buying new ones.
Soooo…crap. There’s something wrong with my fluid. I checked the drained fluid this morning…no loss of air bubbles and no separation. Looks exactly like it did when I drained it yesterday. Still same viscosity, still the color of a cup of coffee with cream in it. Or caramel colored. Will have to bring some of it out to test this week.
Does it matter that my hydraulic fluid is from an HST? My tractor is hydrostatic…the same fluid runs the hydraulics, transmission and rear axels.

No… It’s not about the fluid you just put in. :sadsmile: There’s something wrong with your tractor. Doesn’t matter that it’s a hydrostat. Except there’s more expensive things for the contaminated oil to mess up. Precision metal parts operating close together don’t live long in watered oil. Don’t delay getting this fixed and the oil + filter changed again. Most modern tractors use a common tank for the transmission, brakes, hydraulics, steering, etc. Makes for a single point to check fluid levels.

I did think of another source of water. Your coolant. Some tractors have a oil cooler connected to the engine cooling system. The engine cooling system is pressurized at operating temperture while the hydraulic system is open to atmoshere. Check the level of your radiator water. If it’s low, I’d suspect it’s going into your hydraulic system.

[MistyBlue]

Double crap…my coolant level is low. Just checked it the other day when I was heading out to get all the fluids for replacing everything in the tractor. Sonofabitch…that’s something I can’t fix. Time to call in a mechanic. Just won’t use the dealership, they’ll charge me at least $5k most likely if they charged over $500 for a battery.
Freaking figures…made the last payment on the damn thing last month. :mad:

That’s what happened to my FIL’s tractor. His was an old International. (first tractor I ever loved:yes:) He had it fixed, and he is ‘frugal’ so maybe it won’t be that $$$ bad.
I have been fighting with my stupid riding lawn mower, replaced the started, new spark plug, since the old one had rust on it. There was a mystery wire left over, black, looked like just a ground wire, so I put it on a likely looking bolt, then the battery died. It is on the charger now. Of course my 25 yo charged stopped working so had to go get a new one. Fiddle dee dee.
Somebody called my lawnmower a tractor. No it does not have a PTO. clueless harry half acre. ( I am feeling bitter and jaded:yes:)
Whine over, good luck with your system.

Depending on what it is, it may still be under warranty.
You may want to check that first.

Anyone that works with machinery knows that there is always something breaking or needing fixing before it does.
Better learn to be patient, as you hurry up and fix it.

I’m betting on the head gasket.

[nestoras]

Good morning I’m new to the forum. please tell me how many pickup measures has the new holland 940 and what is the difference from the new holland 286. Thanks

I think that could possibly be a spamming post that just brought a real old thread back to life.
