I had to replace the upper bearing on the steering column of my Ford 600 tractor however when I oput it all back together the tractor won't turn left. Is there any trick or special way I need to align the worm gear when I put it back together to ensure it will turn both ways? Also, since I have it already back together, is there any way to make this adjust without taking the whole thing apart such as disconnecting the tie rods and turn the arms separately? Any ideas would be appreciated. Thanks.
