Just pulled my SC out to replace a smoked carbon ring and found this nut on the end of the supercharger oddly worn down. Its a new SC less than a year old with probably 35 hours on it. not really sure what caused the nut to get warn as the ski runs great other than it eating up the last carbon ring within 35 hours. Installed the new larger 300 model SS ring, and carbon ring around the same time i installed the SC. if you know what could be causing this please let me know. Thank you
It’s ground down from balancing…it isn’t actually worn. No problems, no worries!
