Super a Tranny and Diff.

Is the transmission case lube and the final drive lubericant seperate? IF so, Is there a fill plug for the differential on the Farmall super A? cant seem to find one. Also, is there a fluid level check plug for the transmission case?

Thanks as usual.

Final drive fill plug is same as check plug located on inside of each final drive case. Transmission check plug is behind brake rod on the left side of transmission case.

Look for a 1/4 inch pipe plug on the left side near the front of the transmission case for the level plug. Fill from the top of the transmission near the gear shift, should be a 1 & 1/2 inch pipe plug with a 3/4 inch or so socket extension to remove. Do not fill the transmission above the level plug as the seals will leak and the brakes will not hold once they get soaked.

Just to be clear, the differential is in the same case as the tranny and is filled through the plug in the tranny cover, to the level of the check plug described near the left brake rod.

The final drives (stictly a gear reduction arrangement, not a differential) are indeed separate from that. Fill/check plug is at the forward end, above the pan, on the inboard side of each. What I've found with them is that the recommended volume of gear oil is les than what it would take to rise to the level of the fill hole bu that, once installed, there's no way to check the actual level without filling her up. As long as the pan gasket's good, no harm/no foul.

So you would fill it up to the level of the plug correct. This should not harm anything?

Two ways to go at it. If yo've got the stuff in the quart bottle that let's you see how much you've poured in by looking at how much you have left, you can put in the three pints and be okay as long as you're sure you've got at least that three pints in there.

In my experience (driven by curiosity and no more scientific than pokin' my finger in one try and some cardboard in aother), the three pints doesn't bring the level up even to the top of the pan. By rights, that would make sense. The lower edge of the fill hole is in the casting above the top of the pan. Why would you fill a pan so full that it would overflow if you ever went to remove it?

From my experimentation, you could probably sneak a whole two quarts into each side and never give it another thought. If, after that, you wanted to fill it on up to the level of the fill hole, it wouldn't hurt anything, but I'd run it at the recommended level for a while first, just to get some oil into the gasket for long enough to make sure it's swelled shut, and maybe prevent a minor leak at the top of the pan later.
