Hy-Tran Fluid Question
 

The manual calls for Hy-Tran Fluid "or" SAE- 30 engine oil in the transmission. Any preferences? Would some JD trans fluid work just as well? I happen to have plenty of that at the farm for my utility tractor. Thanks

The manual for what????:Huh:

Sorry, I always forget to say it is CC 100. Thanks

Can't get much cheaper the 30 wt.
That's what all my gear drives get when changed

Is it equivalent to Dexron III Mercon, ATF? If so, it will work.

I use 2 fluids in these machines,, Hy Tran equivalent,, and Hy Tran equivalent.

Hy Tran equivalent is $25 for five gallons at TSC,,

My Gravely 24G does use 30WT in the transmission,, but, automatic transmission fluid in the hydraulic system,,
I would prefer one oil,, like Hy Tran Equivalent,, ::bigeyes:

Did I mention that in Cub Cadets I prefer Hy Tran Equivalent?? :bigthink:

:biggrin2:

I use the hy Tran equivalent from tsc as well in the hydros. SAE 30 in gear drives like your 100. No issues

Couldn't agree more. Or, pay $25 for 1 gallon of HyTran at the dealer.

The last time I really read the IH owners manual was 1980,, when I got my first Cub Cadet,,

Back then, I assumed the 30WT oil message for the transmission was a note included for owners outside of the USA,,where getting Hy-Tran may be next to impossible.

The Hy-Tran is so much closer to the design application of the transmission as compared to engine oil, I would never use engine oil in a gearbox,,,

I remember reading about additives that are in hydraulic oil that are much better at lubricating bearings and sliding parts than engine oil.

The additives (which I think one is zinc? :bigthink:) would not work so well in an internal combustion engine.

All that being said,, these machines are so over-designed,, the choice of either oil is probably of little concern,

Clean oil is probably MUCH more important than type of oil, especially in a gear drive.

You sure about that? Thats $1.25 per quart.:bigthink:
