16. Use Tooling (A) in order to remove bearing cup (21) from circle drive housing (4). 17. Use Tooling (B) in order to remove bearing (22) from circle drive housing (4).18. Use Tooling (C) in order to remove Duo-Cone seal (23) from circle drive housing (4). The following steps are for the assembly of the circle drive.19. Make sure that all of the components of the circle drive are clean prior to assembly. During the assembly, check the condition of all of the O-ring seals that are used in the assembly or the Duo-Cone seals. If any of these seals are damaged, use new parts for replacement. Before installing the Duo-Cone seals refer to the section for installation of the Duo-Cone seals. 20. Use Tooling (C) in order to install Duo-Cone seal (23) to circle drive housing (4). 21. Use Tooling (B) in order to install bearing (22) to a depth of 2.00 0.50 mm (.079 .020 in) below the surface of circle drive housing (4).22. Lower the temperature of bearing race (21). Install bearing race (21) to circle drive housing (4). 23. Heat gear (20) to a temperature of 150°C (302°F) for 20 minutes maximum. Install gear (20) on shaft assembly (16), to the location that will allow retainer rings (18) and (19) to be installed.24. Install retainer ring (19) to gear (20).25. Turn gear (20) over and install retainer ring (18) to gear (20).26. Turn gear (20) over and install washer (17) to shaft assembly (16). 27. Install shaft assembly (16), washer (17), retainer ring (18), gear (20) and retainer ring (19) (as a unit) to circle drive housing (4). 28. Heat bearings (15) to a maximum temperature of 135°C (275°F).29. Install two bearings (15) to worm gear (8) until they are seated. 30. Install worm gear (8) to housing (4). 31. Lower the temperature of bearing cup (14) and install it to adapter (10), until it is seated.32. Install O-ring seal (13) on adapter (10). 33. Torque nut (11A) to 20 N m (15 lb ft) and nut (11B) to 40 N m (30 lb ft). Then, torque nut (11A) to 80 N m (60 lb ft) and nut (11B) to 80 N m (60 lb ft). Rotate the worm 3 revolutions then back off the nuts. Torque nut (11A) to 20 N m (15 lb ft) and nut (11B) to 40 N m (30 lb ft) and then torque nut (11A) to 40 N m (30 lb ft). Rotate the worm 3 revolutions. Torque nut (11A) to 40 N m (30 lb ft) and nut (11B) to 40 N m (30 lb ft). Measure the average gap between the housing and adapter at the locations being torqued. Subtract 0.145 0.065 N m (0.107 0.05 lb ft) to obtain the desired shim pack thickness.34. Install nuts (11) and the washers that hold adapter (10) to circle drive housing (4). 35. Install pin (9) in coupler (7). 36. Install coupler (7) to
