IH Torque Amplifier Transmission Lubricant Additive or wo...

Little 504 Farmall

New User
Repairing Rad and replacing the water pump, and before reassembling, cleaned off manual steering gearbox on this 1962 Farmall 504, with dual front wheel tricycle steering. Pops said it has not been serviced since new. Local CaseIH dealer has
no equivalent to IH Torque Amplifier Transmission Lubricant Additive. Are there any modern equivalents?
 
As pointed out by sflem, IH sells "Hytran" Hydraulic Transmission Fluid. JD Hyguard and other hydraulic transmission fluids that say they meet the specification fro wither fluid will be just fine. Jim
 
Check for number 407217R1 in a quart can. Think that's what they use for a replacement for the additive in the steering gear.
 
Buy the Orschlens "303" transhydraulic fluid. Right now its $29 for a 5 gallon bucket. 100X better then the 50 year oil thats in it now.
 
Don't want to break the seal to see but from what I remember this is thicker than the hydraulic fluid. Not sure if this can is the same stuff inside as the additive for non detergent oil. Think it would be the additive for the 504 time period though. For off the shelf think I would try 75-90 gear oil.

New one for me

I thought that HY Tran was all you needed as it was basically planetary gear set, dry clutch and some overrun dogs(or what ever they are called).
 
The original IH additive was some black foul smelling stuff that was very concentrated extreme pressure additives. It worked extremely well as a steering gear lube when used full strength and that is what was originally used on those manual gear boxes while it was available. I have no idea if the number Slater gave is that same additive. IH does have another additive now that is to be used in hy-tran if you experience squealing wet brakes and have been using certain formula's of hy tran. I have the service bulletin but not at hand right now that explains it. Reason it caught my attention is I have changed the brake discs on a 5288 that were squealing. They looked like new but the new ones took care of the problem. I did not know of that additive at the time.
That additive has nothing to do with steering gear lubricant at all. If I could get ahold of that original stuff I would use it in that gear box.
 
Went through a 450 several years ago and manual said to use that additive for TA. I went CaseIH dealer and was told that they did away with that additive and Hy Trans would do the job.You don't want to use 80-90 it will screw up the TA soon or later.
 
Don"t know how this got to transmission or hydraulic fluid. The question was what to use in a Farmall 504 manual steering gear and bearings. No power steering involved.
Unless its the additive mentioned that was used in the transmissions with T/A mixed with engine oil. This was the time period between gear oil first used in T/A tractors and hytran.
 
Yes Pete that smelly oil kind of reminds me of STP engine treatment oil in constancy. If that's the right word.
Never had any of the 407217R1 oil. That's the oil called for in a 504 parts book and its said to replace 365798R1 Torque Amplifier transmission
lubricant additive.
407217R1 is one quart, $8.42 on one lookup site.
 
For a simple manual steering gearbox, I would think that heavy gear oil is the proper thing to use.

What could a Torque Amplifier additive bring to that party?

Thanks for all the replies. I looked at the present fluid in the manual steering gearbox, and it seems slightly thicker than Hytran, yet thinner than 75w90 gear oil. It has a slight sulphur
smell like mineral gear oil. 75W90 Mineral gear oil would work
in warmer climates, however this tractor works thru out the winter in Alberta (Canada). The other lubricant listed was worm gear oil. Possible combination of B6 Hytran or equiv.
and a additive. Local CaseIH dealers don't stock 407217R1.
 
Just an idea. Why not use Hy Trans and add Lucas Oil treatment. That would make it a little heavier than Hy Trans and helps maintain seals.
 
From my reading of the original post, he is referring to a MANUAL steering gear box. Nothing to do with TA or transmission.

Also, one quart of the TA additive (black smelly stuff) contained as much extreme pressure additives as four gallons of early Hy-Tran did. Thus, it worked very well in manual steering gear boxes to reduce steering effort and reduce galling of the gears.
 
Hy tran only. Ih had a recall on the gear lube causing the ta to slip. Also as a ta builder I have seen the oil ports plugged up and ta burnt up because the hy tran cant get through.
