General Discussion / Clutch fAan vibration
« on: October 24, 2010, 06:49:14 PM »
Hello-
I have a 69 Camaro RS factory AC car with a 7 blade 18" fan. I restored the car then removed the numbers matching engine and currently have a 383 with the previously mention fan and clutch fan. Since teh 3783 was in I purchased a new clutch fan but used my existing 7 balde fan. The clutch fan wore out fast creating a vibration in specific RPM ranges. I replaced the clutch fan with a new one using the same blade. Now the new one has worn out and started to vibrate again.I removed the clutch fan and blade and vibration is gone. My question is could my original 1969 7 blade 18" fan be out of balance causing the clutch fans to fail or have I had a string of bad luck with the 2 new clutch fans? The clutch fan part # is 27071397 and I believe it came from Car Quest.
If replacement is necessary for both what would you run for a blade and clutch fan? Is there a better brand?
Thanks
