Bits and tidbits I have learned and picked up from the find folks that hang out here.

There are no adjustments on this steering gear. All you can do is make sure that everything is as tight as you can get it and then you will need to start replacing bearings and bushings. The good news is that new bearings and bushings where needed will usually tighten these up enough to be satisfactory. Rarely is the worm gear or worm wheel worn enough to need that expensive replacement unless you are really particular. After tightening and checking keys , next thing is to take the big plug out of front of steering gear and check the ball bearing on the end of the steering wheel/worm gear shaft. Shaft and worm are all one piece and ball bearing is clamped to end with castle nut. Any play in bearing or in clamping system will result in play in steering. You can also check by pulling/pushing on steering wheel. If there is any back and forth play, the bearing on the end of the shaft is likely bad or loose. Inner race must be tight to the worm gear shaft and outer race must be tightly clamped to the steering gear housing by the big hex head plug. Sometimes you have to put a washer under the plug to get it to tighten up, but be sure the washer does not also tighten against any of the other bearing parts or the bearing inner race.
Most of these I rebuild have 1/2 turn play in the wheel and hard to steer. i shoot for 1/4 turn free play in the wheel or less and easy to steer. If the bolt holes in the axle assy are oboblonged I weld them up and re drill, worn holes and bent bolts will throw the caster off enough to cause hard steer"n. if i could tell for sure this is the magic bullet to fix steer"n problems I would"int have to git my hands dirty enny more. you are gonna havta take a look. I have had good luck with this kit but always find sumin else worn, most of the time its just a matter of tightening up thinks are replacing the keys etc. most sectors are reused.

You kin rebuild it on the tractor but enny way you go you will need to remove the front axle. Remove the steer’n wheel and then the big nut/cap on the end of the steer’n box and the whole steer’n shaft will slide out. Remove the Pittman arm then six bolts that hold the steer’n bolster and remove, it comes out the bottom. Then you kin remove the sector for bear’n , seal & bush’n replacement. No mater what the bush’ns look like replace’em.
If the steer’n shaft is bent and most are they are no problem to straiten out. You will need access to a press to straiten it.
