This works on Bob Newby Clutches. This tool locks the clutch hub to the clutch basket so you can properly torque the clutch hub nut and engine sprocket/pulley nut.

Steps for use:

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