Just noticed the hydro oil is red in color in my New Holland S14. I bet the guy before me put hydraulic oil in it instead of 10w 30? Guess I will drain it and refill with 10 w 30. Hope it's ok?

Most call for ATF, so red is likely right. You can use other oils though.

This particular tractor calls for 10w 30 motor oil in hydraulic system.

Same pump as many other makes that call for ATF, so nothing is hurt with the ATF in there. 10w30 is better for warm/hot weather or older worn systems, so a simple oil change will take care of that. I doubt very seriously you have anything to worry about.

So now my problem is I don't really know what it is and I'm low on fluid. U think its just ATF?

If you need to add oil anyways, now would be a good time to drain and replace. Like Olcowhand said, I doubt that it did any harm.

Ok thanks guys.

Probably back when that hydraulic system was built. A lot of advancements have been made in lubricants in those years. If one can use hydraulic fluid, or ATF in a $250K tractor why won't it work in a $1k tractor ? ?

Will it get the tractor to move? Why yes. But is it actually the right choice? For some reason the hydro release plunger blew out and leaked oil everywhere. One guy thought maybe using hydraulic oil built up pressure? Who knows? But if my car suggested using 10w 30 I don't think I'd run whatever would work per say. Just trying to get the right answer.
Thanks

IH/Cub Cadet Hy-Tran (a red hydraulic/ATF type lubricant) was used/spec'd in the Cub Cadets that had the similar Sundstrand hydro unit in them. I had a car with a manual transmission that spec'd ATF as the lubricant. Either will work fine in these machines. I like to stick with what Ariens spec'd and run with the motor oil. If I got a tractor that had a recent change/fill with ATF, I would leave it.

As Shorty said, if you need to add, I would change it and switch to motor oil. I never feel bad about changing oil in something I don't know the history on.

In a Wheel Horse it is very difficult to remove all the fluid when draining trans. Therefore you would possibly be mixing two different fluids that are incompatible. How is your situation?

FYI...If you remove the hose at the bottom of the front of the trans, you will get most of the oil out.

U guys are all very knowledgeable. Thanks a lot!

 

[coinman66]

Also, what exactly holds the hydro release plunger in place? Is it the o-ring? Maybe I should replace that?

My Isuzu Axiom specs Mercon 3 in the transfer case. My 318 specs ATF. If it is good clean oil I would not sweat it.

to totally ger all the old stuff out, you may have to drain and fill it a couple times with what ever fluid you "want" to use (new filter too each time) run it to get it good n warm in between each drain and fill.

New Holland has a multi 134 oil in them which is red in color so the dealer mechanics know that for warranty purposes you have used their recommended oil! As a suggestion use what the manual recommends and you will not regret it. Factory specifications are usually in your best interest as the manufacturer does not want farm equipment and such breaking down.

 

[shorty]

If the release came apart once, it most likely will again. I don't have a Vickers hydro to show how it is put together.

I know a guy that ran Marvel Mystery oil in his hydraulics, nothing but, for years. They are not particular.
