Was moving hay and there was a pop under the cab, I made it home but lost power to the trans. This is a power shift. No reverse and barley move in forward. Finally got time to split the tractor to repair the clutch and found this when I pulled the seal cover from the input shaft. The nut was broke with part of the bearing housing still in it. I’ve never been further into a trans before and am unsure exactly what is broke the outer snap ring was loose as well. Any thought as to what it would take to repair this or is it junk? Attached some pics for reference.
