Like the title says, I just noticed last Saturday while I was at a car show and showing someone the engine, my alternator / crankshaft / water pump belt is starting to fray and shred on the inside closest to the engine. It was a brand new belt I put on back in the summer of 2015, and have barely driven over 3,000 miles on it since the car has been restored.
Back in late April of this year, I had the car trailered up to DMC Midwest to have some work done on it. While it was there, they replaced the exhaust manifold gaskets on both sides of the engine. Is it possible that they had to remove the alternator to replace those parts and when re-assembling it, got something out of alignment? I haven't crawled under the car yet to see if anything sticks out as obvious, but the only thing I can think of is that it's possible a washer or shim was put back in the wrong place / order and it's now just a hair out of alignment. I did notice that somehow I ended up with all new yellow zinc plated hardware back there too. Not complaining, but it was a surprise to me. They also replaced the heat shield in front of the muffler, along with new zinc plated hardware there as well.
It's not shedding bad (i.e. chunks missing), but there are fiber strands sticking out all along the back side of the belt that weren't there before. Any clues to look for?
