I'm not convinced it was seated all the way. The secondary I know for sure was lined with the cogs on the gearbox. The one way bearing does operate correctly, it was just a fight getting the primary bolt to screw in easily.It’s hard to say but I’m wondering if the primary is seated all the way. Also are you sure that the cogs on the gearbox countershaft lined up with the slots on the helix and the secondary went on correctly? Before you install the belt, the one way would spin in one direction and lock the other way?
