Classic Beetle Generator Woodruff Key
I put a new generator into my car in October. All things considered it went fairly smoothly.
However I had the generator shaft rechased as the threads were not right and I could not get either the fan nut or the pulley nut to thread onto the shaft.
Recently the fan belt has been getting loose, I will tighten it and a few days later it will be loose again. A few days ago I fired up the car and it sounds awful. Turn it off and find the generator pulley is wobbling around.
I've been busy stripping the car to OG paint so haven't had a chance to look at the pulley until this morning, here is what I found:
The slot for the woodruff key on the back half of the pulley is no longer straight.
The front half of the pulley has those angular shapes cut into it now. The edges used to be straight. For reference it was a bugpack spin-tru pulley.
One of my pulley shims (the outer most one) now looks like an oval.
So what's the problem? Did I buy a bad generator with a warped shaft?
Or is it simply a bad pulley?
Alternatively I had a hard time getting the woodruff key to seat into both the generator shaft and the back half of the pulley. Could this be the problem?
Or did I just f*ck things up when I put it all together the first time?
Thanks for the help
