   1. Tighten the tie rods to the first torque value. Tighten the tie rods in the cross pattern that is shown in Illustration 3. Refer to Table 3 for the proper value of the first torque.

   2. Tighten the tie rods to the second torque value. Tighten the tie rods in the cross pattern that is shown in Illustration 3. Refer to Table 3 for the proper value of the second torque.

   3. Tighten the tie rods to the third torque value. Tighten the tie rods in the cross pattern that is shown in Illustration 3. Refer to Table 3 for the proper value of the third torque.

      Note: When you are heating the tie rods, make sure that the flame does not directly touch the body of the tie rods .

   4. Heat the tie rods in the cross pattern that is shown in Illustration 3. Do not heat the tie rods to a temperature that is greater than 300 °C (572 °F). Use a 1U-8865 Infrared Thermometer in order to verify the temperature of the tie rods.

   5. Tighten the tie rods to the final torque. Turn the tie rod for the distance that is specified in Table 3.

   6. Allow the tie rods to completely cool before using the hammer.
