hytran oil?

rustred

Well-known Member
i have this old 560 with a loader on it i got running. resealed the loader cyl's. as just wanted something to feed cows with. it sat a long time. so like a dumb azz i started it up without checking transmission for water. sure enough shifter was loose and water got in. so drained whatever water would come out now oil is milk.
SO... i will drain it and want to know if there is a problem to just fill it with say... 1/2 gear oil and 1/2 regular hyd. oil. i want it to be thin enough for the pump in winter. tractor will only idle around lifting a few bales in winter. not going to be used for pulling where it would matter for the differential. i want to basically just have hydraulic's working. right now with this oil it will not even pick up a bale "leon loader". dont want to buy and dump in new hytran oil as i already have this oil here. myself i dont see a problem using that mixture, or even just straight hyd. oil. i still will check the hyd. filters. what's the verdict on this?
 
I think you have enough potential for trouble with the water mixed in and without compounding it with gear oil. Idling around in winter will never get the system warm enough for the gear oil to work well or drive out any remaining moisture.

I would get a bunch of the cheapest HYTRAN COMPATIBLE oil. Drain the system, do a partial refill to get enough oil for the hydraulic pump to pick it up. Run the hydraulic system through several cycles and drive the tractor around a bit. Drain the system as completely as possible and clean the filters. Repeat this until the oil in the system looks like hydraulic oil.

Your tractor, you can do what you want. But that is what I suggest.
 
my plan is to clean and flush the system. i want to know if i can use something other than hytan oil as i suggested. it is an old tractor sitting here just to use as a temperary fill in. and i do know gear oil is too thick. i basiaclly want to know if i can use standard hyd. oil. instead of hytran. i dont want to put 300.00 of oil into a 500.00 tractor. i ask because i already have standard hyd. oil here, "not hytran" i basiaclly just want to pick up a bale of hay for the hay burners, no other use . standard hyd. oil is used in truck hoists so why not just to power a tractor loader, its not going to hurt the gears as i say because the tractor will not used to pull. just drive up to bale and lift and move and dump bale. what im saying is hytran has some additive for gearing. so im basically not using gears under load so am i safe to use plain old hydraulic oil? this is my own experiment and take my own chance and no finger pointing,just asking for opinions. i dont want to put hytran in this tractor, dont care about tractor... it is junk. using it till i can install loader on diff. tractor.
 
With Orschlens selling their "better grade" hytran capitable trans hydraulic fluid for $30 a 5 gallon bucket - how much more cheap do you want to go?

The cheaper grade "303" is only $20 a bucket.
 
nobody has given me an answer to my question yet. yes i know jim is correct as i know all that info also.
all i want to know is how will a " non" hytran oil damage the gears if the tractor is not used for pulling a load. ???all it is about is running the hydraulics with a standard viscosity plain old style hydraulic oil. let me put it this way also...if tractor is stationary why do i need hytran oil??? as i do not believe i need hytran to run hydraulics.
 
Using the Hydraulic Transmission Fluid from a Big box, or Farm store is Good as long as it meets the IH Hytran Specification. Go for it. It will not harm the tractor even if you do use it hard!! Jim
 
rustred the problem is only if you want things like the TA to work. There are clutches that need that oil if you want them to work over long periods of time. For just flushing out you could do as you want to. You could also just heat the oil you drained out to evaporate the water and reuse to flush with. We have a tractor that had your problem, and still not sure how water gets in it. We hated the oil to get the water out and reused it then did it again. You could save some flushing work by blowing out any lines you can get to ahead of refilling and running.
 
Agreed. The oil will most likely "layer" and not "mix". Running 90W through a hydraulic pump meant to pump the equivalent of 20W in the winter will result in a ruined hydraulic pump in very short order.
 
Except the Sprag "clutch" that holds the TA body from turning opposite engine rotation when the lever is back is sensitive to the viscosity and additives in the trans oil. the original introduction had issues with oil causing slipage of the TA and a special additive was used to "fix" it. Jim
 
I know the TA it self needs the Hy trans oil or oil that meets Hy Trans specs. But the main clutch of tractor and the TA clutch are dry clutches on a 560.
 
you guys all missed my question, i want to put a non hydraulic transmission oil in this tractor. because i have lots of that oil that i get from work oil change outs. if its used in piston pumps it will work in a tractor hydraulic system . and the reason for using a hydraulic trans oil is all about the diff and trans gears getting proper lube.i want to know if and how can gears get damaged fron non hydraulic trans fluid if the tractor is not put to work. that is my question. people put deisel in their tractor trans. and drive them around to flush them , supposedly dont hurt a thing. so why would a non hyd. trans oil hurt it? it has nothing to do with hydraulic pumps needing it.as i said, im not using this tractor , its only to lift up a round bale of hay and dump it in the bale feeder. it will sit by the bale stack. i have 60 tractors so have no other use for this tractor other than the loader.
 
The problem with using regular hydraulic oil like AW 22 or AW 46 ( I believe that's the numbers) is that it doesn't "cling" to the gears and bearing surfaces in transmissions and differentials, yes it works in hydraulic systems with piston pumps but the piston pumps require a different type of lubrication. Not all Oil is created equal. It just doesn't offer the lubricating abilities of trans hydraulic oil, and really regardless of how much you'll use it the oil doesn't stay with the bearings or the gears, and Murphy will rear his ugly head and the most inopportune time, if it were me knowing how much you're going to use it I'd take the other guys advice and find a cheap Hy-tran equivalent to use, I get what you're trying to do, but those tractors don't hold all that much oil.

If you really enjoy tearing the trans & rear end apart to replace bearings & gears go ahead & run straight hydraulic fluid.
If you would like to have a bit more dependable piece of equipment, drain what oil you have in there & replace with Hy-trans equivalent. Once it gets cold enough the water in it now will freeze and disable the tractor, until you can eventually get it thawed out.
TSC sells Traveller brand Premium Universal Tractor Trans /Hydraulic Fluid for $26 for 5 gallons. They also sell it in 2 gallon container for $15. 7 gallons should be plenty.
