I have used this weed trimmer for more than ten years since making this repair and it has been as good as factory new. While the clutch now runs in open air inside the steel "L" tabs, it would be near to impossible to acquire an injury from the spinning clutch. You might never need to make this repair, but what I did might provide an idea for you for something you will need to do.
