Manual says 90wt in diff and transmission. I have a bunch of 80/90. I'm going to use it unless every response is a loud NO.
Thank you for any advice. At the very least it's worth what we pay :)

It's a superior product to straight 90 weight. Will flow a bit better in cold weather. When it's 97F outside it doesn't matter! Haha
 
Just think of how many of these machines are running around with 50/50 water / gear oil grey sludge in them!

Not that I would recomend the "grey sludge"!


You could even use hydraulic oil if you want!

Pretty sure I read where the late late models was speced as using hytran and the number series used the trans case as the hydraulic reservoir if I am not mistaken.
 
How about 85-140 for a tractor used exclusively in the summer :shock:
Jim. P S. Might help quiet the gears some.
 
I think the only time I have used straight 90 weight oil in the last 5-10 years has been in the transmission of my International Scout, which calls for a specific type (I don't recall if GL1 or GL5) for the bronze bushings in it.

Must have been GL1 which is a straight mineral oil and compatible with yellow metals like bronze bushings. GL4 and GL-5 gear oils contain extreme pressure additives that are corrosive to yellow metals. The PTO shaft pilot bushing is bronze. GL1 motor oil is pretty scarce these days, but you can also use Hytran, which can be used with yellow metals.

Very good point ! 100% of my tractors came with this mix
 
Shifting a little bit..... what is the correct way to re install the tapered bushing on the PTO shaft. I now know the INCORRECT way to remove this and the pulley.

I had a chocolate Milkshake mixture in trans and rear diff. I appreciate all the input.

I had that. I had to do a change in the cold because it was in a snowplow tractor and I could feel the gear shift be sluggish. Now all winter-run tractors will get a trans oil change in the late fall.

My bottom line on oils is that if the engineers at IH had access to modern oils they would be have been specified in the manual. The manuals were written before the modern oils were really around in the mid-1970s. I use the modern multi weights with better properties. In this case "doing per the manual" is not the best option.

Gl-1 is correct, I checked the bottle today. I remember going to buy it in 2019, the kid at Napa looked in the computer and said he couldn't get any. I ended up finding a 2 gallon bottle on a dusty shelf in the back of the store.

Won't hurt it one bit. There heavy gears that will still get oiled but probably overkill. And I'd hate to have it if you live in cold temps and then think I'd feel it necessary to change it out in winter, worried it wouldn't lube well...of course if it never got up to operating temps it should still act like 85w.
