Well, I have been trying for the last day and a half to get this steering dial in an maybe I am just over thinking it or overlooking something simple....hopefully, someone can help out that is familiar with the manual steering on these tractors.
Those that are familiar, there is a mechanical stop on the spindle "knuckle" itself that limits how far the spindle can rotate. It allows a certain amount of travel and no more.
The pitman arms on the steering gearbox can only move so far also.
Well...these numbers are exactally the same when measured. No issues if the front axle is level. But when the front axle tries to pivot:
On the side coming up, the distance is getting shorter between the spindle knuckle and the gearbox pitman arm.
On the side going down, the distance is getting longer.
The issue is the knuckes on the spindle are against the stop. This causes a bind. Not sure how I can adjust anything to make the issue go away. Cause the gearbox and spindle travel is the same. But nothing to account for the front axle pivoting and changing things.
So just wondering if this is the way it is supposed to be?? And when the axle pivots, it just feeds back through the steerng colum??
I have also had the steering gearbox appart. Which leads me to my next question...
The left hand shaft, that has the nub driven off the worm gear, has 3 teeth. The right side has 4 teeth. So common logic, I put the center tooth of the 3 gears in the middle of the 4 teeth of the right. But that puts the alignment mark way off on the pitman arm. Thats not a huge issue as I can jump a few splines to compensate, but the way I took it appart, the gears werent centered. The middle tooth of the 3 gears was between the first and second gear on the 4-tooth shaft. Just didnt seem right. And would also cause a lot of slop when the right side pitman arm was at its furthest forward position.
I dont think thats the issue though. cause I can (and did) re-position the pitman arm to compensate. Hopefully someone has some knowledge of these gearboxes. Not sure what else to do.
And if anyone has a 300u with manual steering, One thing I would like to see is a shot of the left and right side pitman arms, with the wheels pointed straight ahead.:thumbsup:
