Transmission and differential oil for a NAA

I'm about stumped with all the misconceptions about what you can and can't put into a NAA tractor. I'm about ready to put in the same oil as the 8N uses, as it is a GL-1 lubricant.

The NAA specification was Ford M4864A - SAE 80 mild EP winter and summer in all sumps. For cold weather they recommended thinning the oil in the hydraulic sump with M4864D which was a thinner loader oil.

None of those oils were GL-1 oils which by definition contain [b:e94759597d][u:e94759597d]no[/u:e94759597d][/b:e94759597d] EP additives. A modern UTF is a very close approximation to the original M4864A viscosity specification and has a GL-4 level EP package. It also has a much higher viscosity index than the old Ford oils making it a much better cold weather hydraulic oil and eliminates the need to thin the hydraulic sump oil in frigid conditions.

Simple, inexpensive, and readily available.

For extremely cold temp's, I recommend keeping the tractor in a sheltered environment such as your garage. However, one of those stick-on round crankcase heaters should be installed and plugged in if'N you want her to push snow and she needs it done, right a way. Round. magnetic base 110v. htrs.

Suggestion seconded. If you live where it gets cold and you use the heavy stuff in your hydraulic sump you'll be astounded (and not in a good way) by the sounds that your hydraulics will make on a below-
freezing morning, if they even bother to move at all. Good MC-134D UTF will find all the little leaks and drip onto your floor more in summer but you can use it all year around in both your tranny and
hydraulics.
 
Have a look at this New Holland Lubrication Chart for the Ford N Tractors and let me know your take on it:

I agree.. UTF is easier and cheaper nowadays for multi sump machines.

About the only place I use a dedicated gear oil now are the rowcrops with bull gears and drop boxes.. I'll still run gear oil in thier rears. heavy stuff too. 85-140
 
John, those differential hydraulic oils back in the day were non detergent oils. Non detergent oil allows the dirt particles to fall out into the bottom
of the sump and be taken out when you change the oil. The newer detergent oils keep the dirt particles suspended so the dirt particles are
taken out as the oil passes through the oil filter.

If you do not have an oil filter for the differential and hydraulic system then non detergent oil is for you.

At the age of our tractors this is a miner point.

I can tell you from experience as I have a TO35 Ferguson, if you put 90 weight GL-1 mineral oil in the hydraulic system it will be a bit slow to react on a cold morning, but I have found by the
time the motor warms up the lift is ready to go, just depends on the condition of your pump, worn out pump will be much longer.

All these factors need to be considered as you chose a oil since it takes 6 gals or so to drain and replace the oil.

The M2C-134D designation was Ford's specification for what amounts to a modern UTF. Why that chart singles out the NAA for 80W90 gear oil in the hydraulic system is a mystery to me. It used the same pump and nearly identical control valve as the Hundred series which calls for 134D. Either way it's much ado about very little IMO.

I stopped at Wal-Mart and bought a 5 gallon bucket of Shell Rotella UTF that lists the Ford 134-D requirement on the back.
 
I have always used Ford 134 fluid. When you guys are throwing out the acronym UTF..... Do I assume you refer to universal trans fluid???.... Ford 134 is way to pricey.. I had decided to switch next time around!

The OEM oils (CNH Ambra 134D, Kubota UDT, JD Hy-Gard, etc.) are pricey versions of a generic UDT. There may be subtle differences in the formulation that affect brake, hydraulic, and transmission performance in high tech modern machines but even that is debatable. In an old Ford they are going to be indistinguishable. My Kubota HST hasn't seen UDT since it went out of warranty ;-)
