The Rollers will not touch the helix unless under load such as driving. There are 2 angles on the helix- one the rollers ride on during acceleration and the other on the opposite side that the rollers ride on during deceleration. It is normal for the rollers to go back and forth between the 2. Also when you first install the belt the helix and secondary need to be operated to allow all the components to relax and be in the proper position. this being said the rollers may not touch at idle.
