Hydraulic fluid question

Fast eddy doesn't have a lawn and probably mows his weeds with a Lady REmington. I have 3 sub zero turn mowers and I use 20v50 whenever I run out of hipoid. The poid is better to prevent cavitating but it doesn't really matter if you only have 8 acres like I do. Used hipoid (lowpoind) is good too but it's getting harder to find since Obammy stole the election.

Maybe that's Gunner's problem. He's been using "detergint" oil. That's used oil into which he's poured a cup of Tide...

Oh. It's not Gunner.

Stop trolling Bonkers! We all know its you impersonating all the trolls and fast eddy. Your lamppost is reserved and I have requested video of your disembolwment. laugh laugh laugh

Exactly what I said.

Be surprized. I just reconditioned a 15 ? year old John Deere 175 Hydro lawn tractor last fall, and the spec for the hydro oil is multigrade engine oil. I thought it was 20W50,but I pulled out my manual id it was 10W30 for either the Sunstrand or Kanzaki hydros, and #30 for the Eaton. I know quite a few people use their normal all-fleet oil in their hydros - Rotella "T" 15W40 - which is also used in all the engines on the farm - gasoline or diesel.

When I asked the JD dealer he said do NOT use HyGuard in the little hydrostatic units - both Sunstrand and Kanzaki specify motor oil - not hydraulic fluid, as does Eaton.

Would HyGuard hurt?? Most llikely not - but why take a chance?

Because a hydrostatic transmission more closely resembles an engine than a hydraulic cyl?? There are pistons and swash-plates and all kinds of rotating and sliding parts running under high pressure, speed and temperatur - just like an engine.

The circle 3 was all-fleet oil - for many years it was made by the shell refinery - basically the same oil as Rotella. Valvoline made a good all-fleet too years back - not quite as good as Rotells - and Texaco had one too - I think it was URSA. - also a very good oil. Citgo made the oil for Farm and Fleet for a while too, I think There are some other smaller refiners that make some of the private brand oils as well

Shell made the John Deere universal hydraulic fluid (HyGuard) 10 or more yrears ago for at least the Canadian market. No idea if they seill make it. (and there are at least 3 versions of HyGuard - normal Hy-Guard, low viscosity HyGuard, and Bio HYguard made of Canola oil. HyGuard Noise Reducing (with a friction modifier in it to quiet chattering clutches in the powershift transmissions and wet disk brakes - on Gators and utility tractors in particular)

There is also "noise reducing THF" sold by Deere for use in place of HyGuard.- HyGuard Noise Reducing (with a friction modifier in it to quiet chattering clutches in the powershift transmissions and wet disk brakes - on Gators and utility tractors in particular)

THe PEMO additive is also available separately to add to regular HyGuard

They don't average, but the API specs REQUIRE the oils to be compatible with each other. Any SJ oil has to be compatible with any othe SJ oil to allow topping up an engine without doing damage to the engine, and generally adding an SM or SN oil to an SJ will not hurt either.

All-Fleet oils today generally meet at least SN and CI - and ujsually CI or CJ +4 - and CAN be used as top-up for any SJ -SM oil in gasoline engines - and any previous spec diesel oil.

API certified synthetics must also be compatible with non-synthetics API rated oils.

Co-oP Circle 3 was produced in their own refinery until Farmland self-imploded around 2000 and sold off all the physical assets...altho I think the specialty lubrication production had been closed before then so that all that was operating was the gasoline and diesel refinery plus the N fertilizer facility...at that time I wasn't on the farm so not sure of the intermediary history. But, "way back" they developed and produced many of their own farm-targeted lubrication products as well as gasoline/diesel...now who licensed "Circle-3" from whom initially, I don't know for certain :) . I noticed at some point the local Citgo distributor had a few barrels still sitting in his warehouse; I bought the last Farmland one from the local co-op a few years ago to keep running it in one of the old tractors that had been on it since it was new altho eventually I went ahead and switched it over as well.

Likely produced in different refineries for different areas - and at different times.

Just like the co-op tractors - some of which were made by Cockshutt in Brantford Ontario,- Some by Duplex in Battle Creek Mi,, some Steiger, some Volvo, and some Duetz-Fahr., some by Huber in Ohio, and Custom Manufacturing in Shelbeyville Indiana also built some.

Something is the matter with your mobile office. I googled on "hipoid" and I get:

Angrenaj hipoid

Angrenajul hipoid reprezinta tipul de transmisie diferentiala care foloseste o roata dintata conica, spiralata, aflata sub centrul angrenajului inelar de pe arborele de actionare. In felul acesta, este posibil ca podeaua masinii sa fie pozitionata cat mai jos.

Yeah, that sounds reasonable.

I only know about American hipoid. The hi is for high pressure which is good in hydrolics. That is one of my skils I specialise in. The poids prevent cavitation as I said. I rebuild more hydrolics in a day than any of you dicklickers see in your lifetimes. Always remember that if your reclycling hipoid that has made it to the ground you must.... must filter out the stones because they tend to clog the funnel. Ask me how I know. Now go back to your foreing internet in your moms basement and let the grownups talk. laugh laugh laugh

If you keep demonstrating your ignorance I will notify the listkeepers that you should be scheduled for impalment. During that process..and long long after you are dead.. you are a really neat example to others not to be a criminal or a d*****ad..which pretty much covers Leftwingers as a rule. Sooner or later..that stake finds a weak spot and it pushes out of your body..often times in the chest, or through the shoulder..or even up through your trachea and out your mouth..or it passes up through your throat and into your skull and through your brain. Generally if it makes it up into your skull..it stops right there..unless you are a real fatty and it busts a hole in your skull and sticks out the top of your head, covered with brain tissue and blood.

This CAN'T be from Gunner. He knows what "Hypoid" oils are, and why they're called that. And even though he's a little loose on the keyboard, he's not likely to spell "hydraulics" as "hydrolics"...

Ed... the other thing you might not have known about high-end ZTRs (not being insulting here...) is that most large commercial ZTRs simply use low- volume (and variable volume) hydraulic pumps with large-volume wheel motors to achieve the speed reduction between engine and wheels. Not very many of the larger commercial units have unitized hydrostatic transmissions -- simply because they're not "servicable" enough in the field to effect rapid repairs.

My Scag Turf Tiger has "off the shelf" commercial hydraulics. I can replace any component in the circuit from most competent hydraulic shops, or from dozens of on-line sources. For instance, my pumps are off-the- shelf Hyro-Gear brand pumps, and the wheel motors are off-the-shelf Ross motors (with dump-valve option). The hoses are custom to the installation, but -again- just made up of standard 2-wire hose with standard crimp fittings.

I don't know ZTRs at all, Lloyd. I do know something about big hydraulics, on presses and the like, and what they say about oil. Obviously, from what you and Clare have said, they're different animals.

Not directly related to hydraulics, but on the topic of specialized lubrica nts - over in the Logan lathe group, the topic of "what oil to use where" o ften comes up. Some of the answers are downright silly for home machines - a friend of mine uses at least eight different oils on his lathe.

Scott Logan, on the other hand, says he uses nothing but #2 way oil on EVER Y PART of his lathe.

I guess the moral of the story is that pretty much any lubricant will work if it stays slippery and doesn't break down in the particular application.

I knew a guy who, after pinching a busted brake line c losed with vise-grips, refilled his brake system from his radiator overflow tank. Obviously not even close to the ideal solution, but it got him home alive.

Ed Huntress fired this volley in news: snipped-for-privacy@4ax.com:

They are. I also build relatively small presses (25-ton and under) for the pyrotechnics manufacturing industry. In those, I use a 'rated' hydraulic oil -- usually from NAPA, because they're just 10 miles away. Different apps.

I have presses out there over 25 years old, running every work day, that have never had a component failure, except for seals and hoses (and I always use repairable cylinders and off-the shelf hoses to make it easier for them) -- I recommend the users change the oil and filters every 2000 hours, or about once a year. NAPA doesn't _seem_ to recommend changing anything but the filters, ever.

Is there a significant difference between "hydraulic" spin-on filters and automotive ones?
