Loose alternator nut on ye olde Gixxer

This only happens to me.

Riding my old Gixxer (Suzuki GSX-R 750 1985) it suddenly started to sound really bad. Bad in the way of total engine failure. Shut down and transport home on a trailer. The noise seemed to be from the clutch. After draining the oil, the clutch cover was removed. Picture below is of the clutch. Notice something on the top behind the clutch itself?

Aha! Something is not okay.. let us take a closer look. See picture below.

No, that doesn´t seem right. After some removal (including taking apart almost the whole engine in the frame) the alternator was pulled out. The alternator nut was loose and the washer (27 mm diameter and 2 mm thick steel) was gone. You can also see that the threads on the shaft was dented.

A new bolt and washer was fastened in every way possible with a help from a friend. Loctite, locking bolt and so on. The nut was actually sanded down for the lock to engage securily on the damaged shaft. It will hold. I also had to take of the oil pan to find the remaining parts of the old washer. The washer just fell down to the bottom of the oil pan.. luckily..and was found.

After mounting it all together with new gaskets and some gasket glue.. it run´s fine again! Yeah!
