I know this is kind of an old thread and maybe someone will read this. I took the clutch out of my 1050 with intentions of replacing the throw out bearing and found something a little odd. Where the drive shaft couples to the transmission, the couplers are backwards to the diagram I found on one of the web sites. The half with the brass bushing is on the drive shaft. In the diagram, it is on the transmission side. I'm thinking this is my vibration. Any thoughts?
