I got my transmission changed in my 31 model 619. But I cannot seem to find what weight oil to fill it with. I've have seen a couple different references that are very different. So does anybody know for sure? 30, 90 or 600? It's a 3 speed behind a 6 Continental 22A.
My local jobber got real interested and checked around - his contacts say that the 600 steam cylinder oil is formulated - has 4% tallow. They have one 5 gallon can here in Des Moines. Is that the stuff?
Anybody need some in Auburn? It's only used in steering boxes, transmissions and rear ends, so 5 gal would last me a long time.

Yes, the real steam cylinder oil is think stuff, I bought a 5 gallon can of the stuff ten years and shared half of it with others and I'm still using it. It's really perfect in steering boxes, because it's thick enough not to leak, but flows enough to lubricate well. The are several different types out there, some are better than others for the transmission, the ones I tired were too heavy until heated up to shift well, but the steering box, and rear end were perfect. The fan hub too.

Just a few thoughts taken from http://www.capitolcitya.org/articles/technical.html 600W Oil
600W Oil was used in Model A transmissions, differentials and steering boxes when they were first manufactured. No doubt that in their early years the proper lubrication was used. As they grew older and limited availability of 600W became prevalent "just any ole oil will do" was the rule of thumb. As time went by the owners paid little attention to the puddles of grease that became a "standard" for the Model A. If it wasn't leaking it must be empty. Or, if it ain't leaking something is stopped up!
As the cars became objects of restoration, investigating the lubricating products revealed that the wrong grade of oil was being used. In some cases the steering boxes were lubricated with chassis grease and this was a death sentence. The transmission and differential was filled with readily available 90 wt (Hypoid 90). That was because more modern cars and trucks used it. If it's new it must be better!!!!???? The end result for the Model A was that the oil leaked out of the transmission. Differentials were not quite as bad but they would also leak.
600W was manufactured and distributed by suppliers for Model A's for a number of years. Then the product changed. More recently the oil marketed as 600W is nowhere near the original viscosity. While we are here, 600W is not the viscosity characteristic of the oil. It is the name Ford gave it. It could have been called Micro Lube or some other exotic name. The viscosity was approximately 240wt.
Suppliers today offer oil that is called 600W. However, it doesn't come close to 240wt oil. So, the Model A enthusiast is faced with the problem of finding the correct lubricant. Here is what I found while searching the restoration archives.
Combining the 600W oil sold by suppliers with STP motor oil additive on a 50/50 basis can produce a reasonable substitute for 600W oil. Another method is to mix 2 quarts of 140wt oil to 1 tub of heavy duty wheel bearing grease and one can of STP motor oil treatment.
You can go to your John Deere tractor dealer and buy some worm gear oil in small containers. Some of the steam guys use it in place of 600W. And while you are there, check out their corn-header grease. I used it in the steering gear of an antique tractor. Of course, I will ever know if it works properly, since it isn't used more than a couple hours a year.
