I recently played around with my clutches and some friends of mine were helping me align the clutches. They took my secondary off and twisted it and said I didn’t have enough preload. So we took it apart and they said the helix had to be twisted around the shaft at least once before securing it on the key. They were really struggling with this and couldn’t get it. I've never heard of anyone that had to do this. They told me there is a special tool to turn the helix around. Anyone know for sure?
