Vid didn't help me, sounded normal, but my hearing is shot (according to my wife) - there are some frequencies that I can't hear at all (thanks to an M16 when I was in the Army - 30% hearing loss in the left ear and about 10% in the right with 100% loss of hearing at certain frequencies in both).
The clutch is die cast and the dies leave flash in certain areas - if it's flash and you sand it, it will be gone and all looks uniform - if it's a crack and you sand it, but can't still see the crack, then get a dye test kit from anyplace other than Amazon and check it.
I won't buy anything from Amazon, Ali Express or Alibaba if I can get it somewhere else even if I have to pay a bit more for it - Amazon like Ali Express and Alibaba are either owned or controlled by China - I go Ebay, Facebook Marketplace and Craigslist then to the on line classifieds - if it can't be found anywhere, then I look for a substitute and last (if all else fails) Amazon.
I bought from Amazon 3 times in 2020 and sent one thing back because it was not as advertised. Hell, I'll buy from walmart.com ahead of Amazon, but Walmart is just as bad and I will go to a local lumber yard, hardware store or Farm Supply ahead of Lowes, Menards and Walmart.
