After hours of fiddling with the alt, I was able to get the third bolt
loose, the one inboard from the toothed adjuster bolt at the top. It
actually comes in from the front like the other two with a nut on the
backside. Once I was able to get it loose enough to allow the bracket to
move with the adjuster, I was able to set the belt tension and get it right.
Initially, I thought that the adjuster was maxed out, so I bought a shorter
belt. I ended up going back to the original once I was able to get the
adjuster working as it should. I'll never be stumped by a W123 alternator
again!!!!!!!
I do have another question. While rolling around under the car, I found a
part attached to the cross member just behind the oil pan. In the middle of
this cross member is a stud/bolt that faces the oil pan. Right now, it has
bare threads at one end. Is there supposed to be a nut on it? What is it
holding?
