NH 134, NH134b,

[Farmmal]

Long story short, thanks to you guys fussing over hydro and the differences, I got to looking at what I have been using in our tractors and Harvester, as well as what is called for by New Holland, Landini, and BEI.

We have been using whatever Universal is on sale, and skipping the factory stickered stuff to save a couple hundred bucks here and there.

But you guys have me thinking that hydro may in fact, not just be hydro.

The old New Holland 1920 calls for NH134.
The traveller stuff at TSC lists as comparable to 134B
Same thing with the service Pro at the local Agco tractor shop, and the "Extreme" stuff at TSC.

Would there be an advantage to finding something that is comparable to NH134 instead of 134B?

And what is the difference? Like I said, This is new to me and 40 years of "Hydro is Hydro", has left me lost.

I can get the service pro for the same price as the TSC extreme and traveller, but what am I looking for as the better buy, and where do I find the info.

Same thing with the Landini, but am looking at the most severe duty stuff I can get, without going to synthetic expense, as the thing racks up hours, and seals that go bad but can't be replaced untill after season.

Thanks!!

Let me give an example ... ExxonMobil, a "major" US blender of conventional hydraulic oil, has at least 6 different mass-market products that would be "AW46" fluids.

Some MAY (I don't know) be substantially identical.

Castrol also offers multiple products that are AW46.

None of these are synthetic. I suspect that there are synthetic AW46 fluids from these guys. Some of the specialist providers offer synthetics.

The application and environment become significant.

In ExxonMobil's case, there are DTE Medium, DTE15, Humble 46, DTE15M, NUTO H, and DTE25 that customers of mine use. There are (VALID) reasons for these.

I know that it isn't ALL marketing, but lots of it may be ... I think that DTE15 and Humble 46 are the same thing.

For MY MONEY, in conventional oils in industrial, moderately well temperature controlled hydraulic systems, DTE25 is my choice. It has the lowest (poorest) viscosity index, but systems using it have, IME, the longest lived components.

I'm also looking for a hyd/trans fluid for the 1992 2120 hss on my parents place. I'm thinking the WM supertech hyd/trans fluid should suffice for the light duty applications that the tractor sees.

We just purchased the tractor with about 2380hrs. Not sure of the prior service history. But, a full fluid/filter replacement and service is in the plan.

Any other recommendations on a hyd/trans fluid?

Local stores/dealers: JD, NH, TSC, WM, CAT, various fleet centers.

Ian,

Despite my ignorance for the last 40 some years, and using whatever hydro is on sale at the tractor shop, the worst that has happened is a few pumps going bad.
Maybe I'm Lucky..dunno.

Plain old Deere Hytrans is always a safe bet IMO, as is the manufacturers labeled stuff. Plan on bending over and getting hurt in the wallet bad for the NH stuff though..NH is WORSE than JD for charging a dollar for a dime.

Mucking through all the off brands to figure out whos is equal to the manufacturer labeled stuff is what is getting me to head scratching. I still ain't gotta clue.

Have had decent luck with the Service pro in our Harvester(BEI Hydro over chain drive) that is really rough on UTF, and in a couple different 30-90hp Tractors. Not sure if it's better or worse than anything else though.

I agree with ya on the drain and swap on the new Tractor.
It's a prudent and smart move.

We do the same thing with any new(Used) tractor, because we know full well lots of guys run hydro untill it leaks out, or the tractor is sold, and Filters get swapped once a year or when they get to it. Have gotten some awfully watery stuff out of a few old Tractors over the years, and those tractors came from folks that I thought better of.

We finally got around to servicing the tractor last weekend. We replaced the hyd/trans fluid and the front final drive and reduction gears with the Supertech UTF (M2C134D rating/approval) from wal-mart. All of the fluid that came out was long overdue for changing. The shared sump for the hyd/trans contained fluid that was closer in appearance to milk than hyd/fluid. How much water caused this to happen, I do not know.

A wix 51536 filter was used to replace the hyd filter of unknown origin and another flush is going to happen before winter. We want to try and flush out as much of the old moisture laden fluid as possible before colder weather.

Engine oil, fuel system and cooling system was also changed/ serviced.

Little update for everyone,

2120 is running better than ever. Since the fluid service we have put an additional 100 hrs on the machine with no negative side effects. I also found a number of loose bolts in various locations under and around the machine. All bolts were torqued to spec and all small leaks have stopped. I also had a loose banjo bolt at the oil supply pipe for the injection pump. Now that that is torqued to spec the tractor run with slightly less clatter, if that is possible. Could be just me though. I also do not have an oil slick over the side of the block, so that's nice. Rotella T 15w-40 replaced the unknown engine oil, so maybe that is helping quiet things down a tad. I'm going to work it another 100 hrs and change the engine oil.

Anyway, Going to give it a little workout in a week hauling logs out of the woods. Hopefully all goes well.
