Yesterday, I was pulling the bumper off the front end along with the grill and lights. I am getting ready to paint the bugger after owning it since 2017. OK, a little long with the upgrade, but hey, I was busy.
So I looked at the alternator as I was working away and thought; The voltage sure has been bouncing around a lot on the gauge lately. I wonder if the belt is loose again.
Well, not so much, but the pulley was about 1/4 inch away from the fin plate. WTH???
How does something like that happen? I have not touched that part in a long time. When I got it off so I could tighten the nut, I noticed that the key way that is supposed to be in there to lock it all up was gone as well.
So has anyone had that happen to them? I surely have not seen such in any vehicle I have ever owned.
Let me know your story.
No not the one about your crazy sister or brother-in-law. I can read those on FarceBook.

Does it have a tapered shaft?
I think I remember putting a pully on with an impact and a prayer after seeing there was no place for a key.
I think it's, at least some Mk2 alternators are like the cam and there is no key.

The shaft is straight, not tapered like on the IP or Cam. More like a lawnmower setup.

So did the pully tear up the shaft from spinning on it?

I caught it in time to prevent any of that. There just wasn't a keyway in the slot, and the pulley was still sort of tight with the lock washer. Getting it apart was a pain, as the keyway is supposed to allow you to take the pulley off and not have the shaft spin. A screwdriver, keenly placed while wrenching, did the trick.
