Hi! This regards my 1989 GSX600F
I heard an unpleasant pinging/clanking sound on my last ride. It sounded like it was coming from behind the cylinders in the alternator area so I just unbolted the alternator and found a mess inside! I wanted to share the carnage for the curious, but also want someone to check out my plan for what to do next.
Pics!
The rubber cushions are rock solid and they have shattered. The gear was clearly wobbling and banging around, probably causing my noise. There is even some marks of grinding on the plate behind the engine gear this one meshes with. The threads on the end of the alternator are toast from the gear wobbling on them and it feels like the alternator's bearings are not in perfect shape (but if I spin it, it does rotate a couple of times before stopping, so they're not completely jammed up).
Now, what I need help with:
It looks like there is supposed to be a washer and a nut on the end, retaining the gear to the alternator assembly. Is that right? I do not see these, so they are probably lost inside my engine.
My plan is to drain my oil and pull my oil pan and hope to find a washer and a nut in there. I just changed my oil a month ago so this is a bit of a nuisance but at least it isn't a huge expense. I'm going to buy a used alternator assembly and put that in. Am I wrong about the nut/washer or should I be doing anything different? Thank you!
