I found the pivot pin sticking out into the altenator bracket. I had a new pin from a dealership here in DC that I had bought. It looked slightly different, so I thought maybe there was a part sourcing problem. However, it also did not go in tightly.
I finally decided to let a bolt, screwed into the pin, stick out to help keep it in place using pressure from the altenator mounting flange. This is a highly temporary fix.
It is now clear that I have a problem with the pivot pin holes on my right side cylinder head. Does anyone know of oversized pins? Has this happened to anyone else?
