Hello I have talked to several people in the last few years that have been putting hytran in tractor rear ends instead of 80/90 mainly because of cost .. any thoughts on this? I should replace my oil in my 1850 and was wondering if this is a good idea .. Thanks Bryan

I wonder if the thinner oil will give as good as lubrication as the thicker oil. I was always told that you needed thicker oil to cling to the gears longer as they were turning.

Heard some guys tried it in older farmalls, and couldn't stand the noise going down the road from the thin oil.

This is an excellent question. i am interested to hear what the forum thinks.
I have been told that gear oil has specific components that are necessary to protect the gears under load to prevent galling and blueing. Things like sulphur and zinc. The old tractors have may be primitive by todays multiple geared, multiple dollar machines but the quality of metal pre 1980 was outstanding and in my mind is about as good as it got before all this CVT and power shifting 36 speed transmission business got out of control. I think using a trans hydraulic fluid might be ok if the tractor is doing lighter and short duration use like feeding or small plot use. When you get digging deep and running all day long haying or cultivating I think the heavy gear oil would be a must.
For a bit of perspective I remember being told to put 15-40 into an 18 speed road ranger under my Pete with about 90,000 lbs of iron behind it. Seemed to work fine and its about the same visc as hydra trans.

White tried this one time on the 2-85 and 2-105 but after about a year they told all dealers too bring tractors in and change back too 80/90.

I talked with a fella on a tractor ride that had a super 77. He said the transmission was really loud, so he dumped in a gallon of Lucas Oil Treatment and it really quieted it down. I tried that on my 880 but didn't notice any difference. I have 2 1850's, 1550, 880, 550 and an 88 that all get 80w90 weight oil. The thing I don't like is the new 80w90 oil is thinner than the old thick like molasses oil.

The only reason I'd use 80/90 wt in an Oliver rear was if I couldn't find 140W oil.

I'd be concerned about brake seals and PTO seal.

I agree with that 100%! I would run 80/90 or 140. Everything when those tractors were designed was made to have a heavier oil for bearings, gears, seals and etc. I bought a 55 gallon drum of 80w-90 it ended up being cheaper then buying by 5gallon pails and changing 3 or 4 tractors its about gone. The more quantity you buy the cheaper it usually is.

Those old oil treatments like Lucas and STP were loaded with zinc and other goodies. I put some Lucas trans seal in my over/under recently and is has slowed down the leaks a bit. Still have to stop to re-engage direct however, that did not get fixed by the magic fluid.

I'd stay with 80W-90. Hytran is for hydraulic and power shift types and has friction modifiers for brakes and clutches, as well as being lighter weight.

Super99, glad to hear your comments, I put fresh 80W-90 in the 880, and was surprised how thin it is. If anyone has a suggestion for something or brand that will quiet down the early straight cut gears and bearing whine, I'd like to hear it. May just go to 85W-140, is that the ticket?
