need a quick answer

Would Cat hydraulic oil SAE 10 weight be an okay substitute for IH HyTran? Thanks, Ellis

I meant IH touch control fluid for lift all for a SMTA Ellis

Almost all hydraulic oil that does not say "transmission" in the wording is not compatible with high pressure gear contact use. Someone may know, but I would not use it in the PTO or transmission (TA compatibility)

I suppose if you don't cross contaminate with other tractors it would work. Will leak out of every worn seal on the system though. This would be due to the thin oil. I would just stay with the same oil that the rest of them have.

all depends what u are doing... . I had an old 560 full of milkey oil. I changed it to the plain hyd. oil as that's what I had and only used the tractor to feed the cows in winter. just idling around u will not hurt a thing. put it in the field and under load and no it will not stand up. gear oil has additives to stick to the gears. the crown and pinion will be under the most stress. transmission not so much. and another thing I have experienced.... about 50 years ago rear diff went out on dads 65 ford 1/2 ton truck. he went to auto wrecker and bought another diff. put it in truck and then filled with engine oil. he was a faller in the bush and used truck in the bush in winter. it was about 150 miles to his work and by the time he got there the diff was howling due to the thin oil. but if he would have put that engine oil once there nothing would have happened. as this was winter and -20-40f. he hated fords also as that was the his first and last one he used to say. fords had round axle brgs., while gm had flat roller brgs on the axles. he said he makes them round ford axle brgs. flat on fords because he used to haul heavy loads of wood and posts home. and for the 560 I used it all winter and then a guy came and wanted it. I told him he better change the trans/ diff oil to hytran cause I don't work the tractor hard. everybody on this forum jumped on me that it wont work with hyd. oil. but tried and tested that's my answer. ooh... and one more thing, my brother changed oil in dads 560 years ago and used hyd. oil by mistake and it got worked in the field for a day before dad figured out about the oil. didn't hurt the engine.

Jim, this is for the lift all only on an SMTA. It takes 7 quarts and does not combine with the transmission in any way. My owner's manual says to use IH Touch control fluid. I think I wasn't clear with my question. It is the hydraulic pump that sits under the gas tank and has the distributor drive. Ellis

I would use it in that system, I would look at the product info on line to assess if it is good for transmissions. Jim

Yes
