12. Remove ring gear (14) from the axle shaft housing. Using a torch, cut the ring gear in two places 180° apart. Cut the ring gear at the position of the locating dowels in the axle shaft housing. An alternate method is to make three welds equally spaced around the circumference of the ring gear to cause it to shrink. Remove the locating dowels for ring gear (14). 13. Remove Duo-Cone seal (15) and outer bearing cup (16) from the opposite end of the axle shaft housing. 14. Remove Duo-Cone seal (18) and outer bearing cone (17) from the axle shaft. The following steps are for the assembly of the axle shaft assemblies. 15. Fasten the rim flange of the axle shaft to Tool (G) with suitable size bolts as shown. Heat outer bearing cone (17) to a maximum temperature of 135°C (275°F), and install the bearing cone on the axle shaft as shown. Be sure the bearing cone is seated against the shoulder on the end of the axle shaft. Allow the bearing cone and shaft to cool.
See, "Assembly And Installation Of Conventional Duo-Cone Seals" in this module.
The rubber seals and all surfaces that make contact with the seals must be clean and dry. After installation of the seals, put clean SAE 30 oil on the contact surfaces of the metal seals.16. Use Tool (F) to install the Duo-Cone seal in the end of the axle shaft. 17. Lower the temperature of outer bearing cup (16), and install it in the end of the axle shaft housing as shown. Be sure the bearing cup is seated all the way down in the axle shaft housing.

Use Tool (F) to install the Duo-Cone seal in the end of the axle shaft. 19. Lower the temperature of inner bearing cup (13), and install it in the opposite end of axle shaft housing as shown. Be sure the bearing cup is seated all the way down against the shoulder in the axle shaft housing. Dowels (19) are used to locate and hold ring gear (14) in position in the axle shaft housing.20. Locate the position of the ring gear in relation to the axle shaft housing by aligning the half holes for the locating dowels. Put alignment marks on the ring gear and axle shaft housing to ensure correct installation.21. Lower the temperature of ring gear (14) to a temperature of -38°C (-36°F). Install dowels (19) in the half holes on the outside diameter of the ring gear. Use an O-ring seal or rubber band to hold the dowels in position.22. Using a press, install ring gear (14) in the axle shaft housing. Install the ring gear with the chamfered side down. As the ring gear
