I don't see anything wrong with your procedures except that .080 which I also think is excessive, is just a little under two full turns of the adjuster. A 3/8 in. fine thread has 24 threads to the inch. One full turn equals .0416. Two full turns would be .0833. I wish I could be more helpful, but I think you'll just have to take them off and examine everything until you find out what's going on.
