I was on a road trip last week and in my travels I picked up a complete three turn, Ross steering box and column from a JD 300. The plan was to just swap the worm into my box after lengthening the shaft. Same spline and thread in the steering wheel. The JD setup is heavier all around. Cross bolt is 3/4” as compared to 5/8”, the follower is bigger and the plate is 5/16” rather than 1/4”.
But then the bad news. The worm moves the follower stud in the wrong direction! Think it as left hand and right hand threads. So that was disappointing.
Guess I’m still on the hunt for a three turn Ross steering shaft. Crap!!
