I have my B7200 steering box apart and was just going to put it together. I was finding that the explanation of how to "time" the sector shaft gear to the steering ball-nut assembly found in the steering box rebuild article to be less than clear. With a little YouTube research, I found this video explanation by Hoye Tractor to be very helpful. Even though he does the work on a Yanmar tractor, pretty much everything's the same as on the Kubota. Here's the link for part 2 of a two part series. https://www.youtube.com/watch?v=-m6xrP3VBxs
Hopefully this will help anyone else experiencing the same frustration I was having.
