There is a "sweet spot" where the cam will stay still. Otherwise, the clip method works according to some other post. Just put clips on the pulley to hold the belt on the two bank 2 cam sprockets and work your way to bank 1. The lowest idler pulley is the last to go on after the belt is set in place. Then pull the tensioner pin. Don't forget to pull the tensioner pin.how can we keep the pulleys from moving when putting the belt on so the lines stayed lined up?
