My 1994 GT18 has a funny issue with the steering- it will turn about 2x sharper to the left, than to the right.
I started doing some research, and at first suspected it would be an issue with the steering gears slipping (which seems to be common). So I put the front of the tractor up off the ground, and had a friend turn the wheel all the way to the right, and back to the left, and there was absolutely no slippage between the steering shaft gear, and the steering sector gear (the 1/4 circle gear that pulls on the drag link). It smoothly went from one side of the steering sector gear, all the way to the other. What I did notice, is that when the wheels were straight ahead, the steering shaft gear was not in the center of the steering sector gear: There are 12 teeth to one side, and 6 to the other. Thus, you could turn the wheel 2x in one direction vs. the other.
The only way I can see for this to be happening, is if the drag link is either too long, or too short. Which leads me to believe that a prior owner might have replaced the drag link with the wrong part. Can anyone think of another way this might be happening? Or, can someone with the same tractor (or another tractor that uses the drag link with part number 137155) measure theirs and let me know how long it is?
