Super MTA IPTO, what type of oil??

Hello, I am new to the MTA and need to change the oil in the IPTO. The manual calls for 10 weight oil. Can I use Case IH hydraulic fluid? I have not been able to find 10 weight at any of my local stores. Thanks, Matt
 
Any hydralic/transmission oil will do.Back 'in the day',there was no such thing as hy/tran....10wt was the 'state of the art'.

Hy/Tran-come on--all they ever used was a 10w.

You need Hytran for the rest of the rear end, due to the TA anyway. May as well use it for the PTO too. It's mostly convenience.
 
Why is the TA a separate sealed unit from the rear end?

What does the manual say to run for fluid in each?

I think I know the answers to these questions, but I will throw them out.
 
According to the manual it takes 15 gallons of SAE 80. You
need to take out 2 drain plugs, one under the TA and one
under rear at the PTO. Fill plug is on top of trans case next to
the steering post and level plug is on the left side of trans in
front of the clutch pedal, but is also a plug on the left side of
the TA at the same level. The manual doesn"t mention this
one, so based on this the trans and TA share the same oil.

That's what I thought. But then they learned the TAs didn't like that heavy oil and hytran was developed. So in the next 30 years with lubricant improvements and knowledge there are better fluids than what the manual recommends.

Was there ever a tech bulletin (or the equivalent) that said you should use hytran in a mechanical TA tractor? Hytran in a Lift-all? Muli weight oil instead of 30? I'm sure I am missing some, but those are the big ones.
 
No idea about the tech bulletin, guess I need to put out another "post". The trans oil is the next thing I am going to change. Matt
 
The history of the fluids in a SMTA was, gear lube when it was new, like 80-90. The 10wt in pto. Some where along the line, IH realized the heavy gear lube was preventing the rollers in the over running clutch(ramp and rollers)from moving freely. Then they needed a oil that would flow better in cool weather conditions but present hydraulic oils did not give the necessary lubrication for the transmission and final drive. With that they had some one develop and additive that could be used with 10wt engine oil to provide the necessary lube and fluidity. We used one gallon per 12 gal oil of this with a fill in the transmission, rear end, TA of all tractors equipped with a TA . After Hy tran came out all TA equipped tractors used HY tran, including the pto. TA units always share same oil as transmission but pto's were a separate housing. There was dozens of service bulletins related to all of these issues.

Then why is there so much discrepancy on all of this stuff? :roll: Not that I don't believe you, but it sure seems a lot of guys are smarter than IH engineers.

This is another case where the information in the operators manual is no longer correct. Manuals were printed in advance of the tractor being released for sale. If changes were made during the production run the manuals were usually updated to reflect the changes. If changes were made after the production run, as is the case here, the manuals were not necessarily updated. That results in a lot of manuals not having the correct current information. Reprints of manuals are normally just that, a reprint of the original manual. The result is you can buy a new manual and still not get the correct information.
 
Do you know if the John Deere standard viscosity hyguard hydro and trans fluid is compatible? I have a several buckets up it that I use in my new generation tractors.
 
IIRC, my 1955-dated Farmall 400 manual calls for SAE10 oil in the transmission, with some sort of additive. It may have been Touch Control additive or a specific Torque Amplifier additive.

Hygard will work just fine as a substitute for Hytran. They both meet the same specifications of MS-1207 or MS-1209... I can't remember which...
 
For extra reading on hydraulic fluid check out the Red Power Mag from a few issues ago. I got a little behind and read a few magazines all at once so I can't say which it is for sure. I think it was the last mag for 12 or the first for 13.
 
I see no discrepancy, as soon as they developed the additive that would take the pressures of heavy loads on gears, it was 10 wt oil and additive. Then HY-Tran was developed and superceded the 10 wt with additive. They never go back and update original operator manuals so they will tell you what was recommended at the time the book was written. Gear lube was no longer to be used in tractors with a Torque Amplifier. This was all covered in service bulletins which are privy to dealers and they pass the information onto customers if deemed necessary.

I meant all the old timers that "never ran anything but 10 wt" refuse to accept that hytran is an acceptable (recommended) replacement.
