Well, I talked to Rudy, and although he's been busy, he hasn't been told of anymore Karmann 62 mm failures other than Red Dogs..... His seemed to have cracked between the two rivets...... Don't get me wrong, I want to hear about failures, but I just want know which pulley is failing. Aluminum pulleys, have failed, we know that. So, I am asking if these failures are the Karmann 62mm? That is all. I have inspected mine and it looks to be fine....but, if others are having problems, I would like to know who they are so I can find out what to look for. Right now, mine is fine.
