Thanks sky so far. I going over in a while to work on it.
That about 3" long bullplug on the left front corner is not an internal drive but a long hex type nut that I can probably easily put a wrench or socket on. I'll remove it but I wonder if it might have been where the input was to the draft control valve that would usually sit in that corner according to the diagram.
I've been through the oil change before and added extra fluid before with no help. However my last oil change immediately became milky and I now suspect that the gallon and a half held in the draft control housing contributed to that. This time when I drain everything, I may add 5 gal of diesel and redrain it to help flush things. I suppose it is not a good idea to pump diesel through the hydraulics to flush them though and then end up with the hy-tran diluted by diesel. I'm still not sure what to do about the drain pipe in the rear of the draft control housing but maybe it can't hurt to take it out for a while.
The cork gasket on top of the housing is not torn anywhere so I am going to reuse that when I'm done. I also got all new bolts for the top plate and will use anti-seize on everything to avoid problems in the future.
Regarding the sluggish/virtually no power steering, I've posted on that earlier this fall. I can barely turn the wheels with no power steering and easier yet with the wheels off the ground(which suggests the hand pump may be ok). The first thing I fixed on it when I got it this summer was the top seal in the steering wheel hand pump that was flowing out all over the steering wheel and below. That didn't affect the hard steering though.
Anyway this is one of the steps I'm taking to go through the hydraulics. Then I will start pulling lines loose to see how much and with what psi the fluid moves. I suspect the main culprit is in the flow divider and pilot valves.
It appears to have both a 17 gpm and 9 gpm pump flowing into and combined at the flow divider valve which operates the loader and backhoe just fine. I still want to flow check it and also check the pressure although yesterday, I didn't see a good place where a tee would go to test it.
Another thing is that it steers better going in reverse (I do a lot of back & forth to jockey around). I've pulled a steering cylinder line to see if there is any leakby in the steering cylinder and found none leaking. The case/ih parts dept. suggested it may be the thrust bearings on the wheels are bad. I haven't check them yet and not sure how much of a job it is to pull those spindles apart but I am looking at the hydraulics first.

Today's Featured Article - Uncle Cecil's Super A Lives Again - by Mike Purcell. A week or so out of most of my childhood summers was often spent with my Uncle Cecil and Aunt Sissie in the small East Texas town of Maydelle on their 80 acre farm. Some of my fondest memories of these visits are those of learning to drive a tractor at the helm of Uncle Cecil’s 1948 Farmall Super A. Uncle Cecil was the second owner of this wonderful little tractor, but it was almost as though he had adopted an infant. The original owner was a man from Minnesota who bought her from a local dea
