Refer to Illustration 4 for the sequence of heating the tie rods and removing the tie rods.
Heat the exposed center portions of the tie rods with a propane flame or equivalent to 275° 25°C (527° 45°F). Perform this process to loosen the tie rod. Direct the flame away from the cylinder of the hammer. Thin steel sheets can be placed behind the tie rods to assist in deflecting the flame from the cylinder. Do not heat tie rods in one spot. Do not heat tie rods to a temperature that is greater than 300 °C (572 °F). Use Tooling (A) to determine the temperature of the tie rods.

The tie rods will remain hot.
Use Tooling (C) and a suitable lifting device to remove tie rod (3). Refer to Table 2 for the approximate weights of the tie rods. Repeat Step 3 through Step 5 for the remaining tie rods.
