• Install the clutch basket, primary chain/belt, and engine sprocket/pulley
• Place the lock up plate in the basket and hub assembly
• Place a primary drive locking block tool in between the chain/belt and the engine sprocket/pulley
• Now you can torque the clutch hub nut and the engine sprocket/pulley nut to the proper specification.
