I’ve been trying to tighten my serpentine belt after replacing my alternator and whenever I attempt to tighten my belt this piece of metal ends up rubbing against it. I’d doesn’t appear in any of the video tutorials I’ve seen and I didn’t take a picture ahead of time so I’m not positive if it was there before. It’s a 1997 with the 2.5L and no AC
What is this in the way of my serpentine belt?

The main engine block assembly kinda, it’s not lose by any means, it’s solidly in its place
The routing is correct, which is why I’m confused as to what that metal piece is touching the belt
Guessing the belt is too long and the extra movement on the adjustable idler is causing the interference.
Does it need to be rotated to point in a different direction and therefore away from the belt?

That protuberance on the timing case is, I believe a throwback to earlier engines without electronic ignition and was for some sort of timing tool. This sort of belt rubbing has come up before on some forum or other, though I cant find any relevant threads.
There is no need for that protuberance on your engine so if you remove your belt, and you can get something to it, you could just saw it off. If you look at the video that Boogieman posted there is no sign of it on the timing cover of the Jeep in the video.

Following. I don't have this problem, but I'm going to see if my 97 2.5 has that same metal piece.
Unrelated, check out my signature for links about 97s and 2.5s. Let us know if you have anything to add.

I don't seem to have one on my 97 2.5. Do you know when yours was built? This may be another relic of the transition years (96–97).
I like the idea from @mrblaine that the belt is too long and the extra movement on the adjustable idler is causing the interference. If the belt were a bit shorter, then the adjustable idler wouldn't have to push it in so far.

Something to add here.
I'm going to assume the only thing that changed was the alternator during this round of work. If thats the case i would compare pulley sizes on the alternators,idlers and whatever was swapped. One of the new components has a smaller pulley If the tensioner is now further inboard.
