I just bought quite a tidy diesel 434. Steering box felt a bit loose and rough, but presumed it would keep working. Bearings then collapsed in the steering box, and it is now unusable. I have to overhaul the box and wondered if anyone could help with a scanned page out of the parts book or an exploded view of the steering box. Is non power steer, so just a plain box, probably not much different to the earlier 414 etc etc. I have hardly used this tractor and my wife is looking sideways at me!!
