It doesn't appear on the diagram, but shouldn't there be something helping to support the plate sector in this hole?

Another doubt is how much the front wheels turn... it seems excessive to me, even hitting the drag links (LH/RH) at the end of the course.
There are ears on the Spindle Asm.(RH/LH), which would limit the spin...but despite looking like wear and tear, on the Axle Asm. (Front), there is nothing compatible with the same wear.
What do you think?

Nothing goes in that hole. You need to adjust both tie rods, as I’ll bet your wheel have major toe out. Also check to make sure the sector plate bushing and steering shaft bushings are is in good condition. If they are worn or the teeth are worn the gears will jump.
 
Yes, according to the diagram nothing there...but a screw with a limiting sleeve would guarantee more precision and less wobble in the secto plate.
Good, sector plate bushing minimal wear...steering shaf bushing, perfect...teeth little wear...
Talk more about "I'll bet your wheel have major toe out", I don't understand.
 
When ZTR's came out all the tractor style mower makers went to "Tight Turn" steering to prove that are just as manovourable as a ZTR which of course they never will or can be unless they go to rear wheel steering ( like a forklift truck ) .
So you now have wheels that just about turn to a right angle and steering shafts that bend all over the place, excessive wear in the fan gear and steering bush .
But apparently this is a good idea because it allows the operator to be a lot lazier
 
I found this material from John Deere... it's not the same sector plate, but it serves the purpose I think.
And it can even act as an end-of-course limiter for the steering.

Front wheel’s should be nearly parallel and straight when the steering is centered . Toe out means the wheel is pointing out. Toe in means the wheels are pointing in. Adjusting the tie rods will change the position of the wheel.
 
My draglinks have no adjustment, they are fixed.
My wheels are reasonably parallel and in line with the steering wheel.
 
I ended up taking advantage of that hole in the plate sector.
I made a bushing, crossed by a screw plus a wide washer and another pressure washer.

Now the plate sector doesn't wobble and there's only looseness between the gears... it's excellent.

However, when I align the sector plate, the wheels are slightly to the left, as is the steering wheel.

I'll have to change the geometry of the Spindle Asm. RH/LH).
