A lot of WEAR - THAT's what! There is a worm gear (on the end of the shaft, part #9) and sector gear (part #44) where the steering motion turns the corner at the top of the steering post. Even when they are NEW, worm gears have a little bit of "play" in them. When they are worn, they have a LOT of play!! When the tractor is standing still, grab your steering wheel and gently move it from side to side, and see how FAR it moves before the wheels even BUDGE. Now, picture this: When you are driving the tractor you are holding the steering wheel so IT can't move and the bumps in the road are grabbing your front wheels and moving them from side to side!! (But at least it is by an amount that is reduced by the ratio of the worm and gear). If you take the top of the steering post apart you will see an "eccentric" (Part # 22) where you can adjust the clearance between the gears to "take up" some of the play. The only problem with that is, the sector gear will be worn mostly in the middle and when you tighten up the adjustment, it will help a LITTLE, but it will be TOO tight on the ends. I don't know if anyone makes a NEW gear. |
