Should I use Hy-Tran?

I was at the local Case dealership and I asked them about the oil they have in store for transmission/differential/rear axle/steering that would work for a '45 B. The guy said just to use Hy-Tran. He didn"t seem too focused on helping me out, so I wanted to double check before I bought a bucket. Will Hy-Tran work for those components? Is it heavy enough?
 
Hytran will leak more readily and it will take longer to be able to shift gears since it will not slow down the spinning transmission as quickly.

I use 80/90 in my Super A and B. The A has been on a 10yrs worth of tractor rides.
I have Hytran in my Super C and it rols real easy!But that was for a tractor pull this past winter.
 
No Hy-Tran use 90wt. The level plug is behind the left brake rod. Final drive fill to 1 inch below the fill plug. You should drain the old stuff out of the tranny then put a gal of Diesel in and drive around a little to get a good flush. You can add some new lube in the pto but it will fill to desired level after driving as there is a channel in the tranny that drains to the pto.
 
For the most part if your tractor was made before 1955, you use heavy gear lube in the transmission. Only exception I can think of is the Super MTA, because of the TA, it needs lighter oil, like Hytran.
 
Just to add, I ALSO had an IH dealer try and sell me Hy Tran for my Super M rear once.(It is NOT an MTA!) I beleive it was the people on this sight that set me straight to use regular gear lube? ;)

I wonder why they do this????
 
I have done it both ways. I have two Farmall M tractors . One has 80w-90 in it and the other has Hytran in it . The one with hytran in it ,has had all the seals changed . Most original seals were of a leather nature and with hytran they will leak because the leather will not stay soft and plyable . The M with the Hytran has the newer seals rubber/neoprene . The Hytran has a additive that keeps seals plyable. I have pulled this M in tractor pulls and have plowed with it and never had any issues with it not being heavy enough, causing bearing failures .
My suggestion to you is use 80w-90 or 85w-140 if your tractor has not had transmission and axles seals replaced. Both oils will work. I use hytran in all my hydraulic systems and transmissions even in my John Deeres" .The M with the hytran has had it in the tractor for at least 20 years . It is a daily user. Sorry for the long rant but this has been my experience . Use what is available and what you are comfortable with in this case.

So should a person be trying to find some of the SAE 90 oil? A lot of the 80W90 and 85W140 that you can buy is GL5 rated.

(quoted from post at 21:40:02 05/01/13) GL 5 rated have zinc additives, it attacks brass etc.

Sorry for my ignorance, but I wonder if there is in fact any brass in our gearboxes? (I have never had to open up my gearbox in 47 years.) The brass is usually in the synchronizers which we don't have.
 
Napa has GL1 90 #65-205 I think, about $67.00 for 5 US gal. Wonder what would happen if you mixed 50-50 GL1 and GL5. The recipe would about equal what GL 4 has in it for EP.

I never saw any in my H and International wasn't one to reinvent the wheel on every machine.

Here are a bunch of photos of the teardown.

Thats about all they show in there lube charts anymore.Problem with using hytran in the letter series is they originally had 90w or 80/90 or even 140. Put hytran in there is a good chance of seals leaking.

PS I am a firm believer using hytran in the number series.

I agree, they are not trying to sabatoge your tractor. They have updated their recommendation.


So does hytran absolutely never have anything that will hurt your copper/brass like GL-5?
 
I used pure HyTran in my 67 Farmall 140 last season and by the end of the season the transmission seal was leaking. Have not gotten around to replacing it yet.
 
The hytran didn't "wear out" the seal. Your seal has been shot for years.

It's thinner so it will leak through smaller gaps than heavy gear oil.
