  9. If the turning torque is outside the specification, use a thicker/ thinner side bearing adjusting shim to adjust. Refer to "SIDE BEARING ADJUSTING SHIM ".
    1. If the turning torque is less than the specified range: 
      1. Decrease the side bearing adjusting shim thickness. 
    2. If the turning torque is greater than the specification: 
      1. Increase the side bearing adjusting shim thickness. 
  10. Record the total amount of shim thickness required for the correct carrier side bearing preload.
