[QUOTE="eric.schimmel, post: 391842, member: 12326"] Ok, so I pulled the bottom end off again and noticed I do have a lot more wear than I ever noticed. I'm pretty sure I'm going to be rebuilding the bottom end. I'm not sure who rebuilt this for the previous owner or if he did it himself but I was missing a ball bearing for the clutch dog; issue 1. Secondly one of the thrust washers was seized to the shaft. Took a bit of work to get that off. Second the clutch dog and the little arm for it show significant signs of wear. This is the side of the clutch dog with the seized thrust washer (reverse side). Is that groove normal? The diameter of the washer is too large for the groove. [ATTACH type="full" alt="ImageUploadedByTapatalk1435769755.711038.jpg"]77363._xfImport[/ATTACH] Forward side. Some rounding. No groove. [ATTACH type="full" alt="ImageUploadedByTapatalk1435769811.255446.jpg"]77364._xfImport[/ATTACH] This is the bracket for the clutch dog. Some signs of wear. Replace?
