I have now seen two 5000 series tractors and a Pro series that have come in with shipper shaft hardware that was loose. I don't mean just a little loose, a lot loose...to the point that everything is flopping around. Given that the bolts that go through the advance casting are held in place with self locking nuts, I cannot explain why this occurs. I can detect no stretching of the bolts nor do I see any wear on the parts. My only assessment is that the bolts are indeed stretching although I cannot detect it.
Has anyone else seen this? To prevent this from happening in the future, should a change to grade 8 bolts be advised?
