Just finished reworking my second C steering gear. First place to look is the worm gear behind the big plug on the front of the steering box. Drive the pin out where the universal joint is connected to the worm gear, take loose the mid steering shaft bearing on the side of the clutch housing and pull the universal joint off the worm shaft. Remove the woodruff key from the shaft. Then drain the oil out of the steering box and take out the big plug in the front. Screw out the worm gear and shaft. The ball bearing on the end of the worm shaft must be tight with no play. It must be held tightly against the shoulder on the worm shaft by the castle nut which is retained by a cotter pin. And finally when installed in the box, the outer race of the worm shaft bearing must be clamped in tightly by the big plug. Any looseness in this bearing or the clamping system results in steering play. Next, jack up the front of the tractor and support it on the flat spot at the clutch housing. I recommend using 6x6 cribbing. Then see if you can wobble the front wheels(I'm assuming you have a tricycle front) side to side or front to back. If you can, then one of the main support bearings is bad and you will have to drop the main steering shaft and worm wheel out the bottom to replace the bad bearings. In the two I've done, those bearing were OK though. I doubt that wear on the worm gear or the worm wheel is causing 1/2 turn of play. It's likely the worm shaft bearing or the main support bearings. The ones I did had about 1/4 turn when I started. When done, both were less than 2 inches and one is only about an inch. If you drop the gears out the bottom, advisable to replace the oil seal on the bottom while you are into it. Also when you are doing this, you can turn the worm wheel 180 degrees on the spines so that the worm gear is wearing on a new spot.
