Start By: a. Remove the circle drive. Refer to Disassembly and Assembly, "Circle Drive - Remove".

Note: Cleanliness is an important factor. Before you begin the disassembly procedure, the exterior of the components should be thoroughly cleaned. This will help to prevent dirt from entering the internal mechanism. Precision components can be damaged by contaminants or by dirt. Perform disassembly procedures on a clean work surface. Keep components covered and protected at all times.

13. Install shaft assembly (16). Remove Tooling (B). Tighten bolts (17) to 150 ± 20N·m (111 ± 15 lb ft).

14. Wait 45 minutes, then remove bolts (17) and retainer (18) to add shims (20) 15. Determine the required number of shims (20) to obtain 2.30 ± 0.25 mm (0.10 ± 0.01 inch) of deflection in spring (21). Use a depth micrometer to obtain the distance from the end of shaft assembly (16) to the flat surface on spacer (19).

16. Subtract 2.30 ± 0.25 mm (0.10 ± 0.01 inch) from the dimension that was measured in Step 15. The calculated dimension is the thickness of shims (20).

17. Install shims (20), retainer (18), and bolts (17).

18. Tighten bolts (17) to a torque of 240 ± 40 N·m (177 ± 30 lb ft).

19. Tighten bolts (17) again to a torque of 240 ± 40 N·m (177 ± 30 lb ft).

Note: If bolts (17) are 1/2-13 thd bolts, follow Step 20 through Step 26 for the correct shimming procedure.

20. Install shaft assembly (16). Remove Tooling (B). Tighten bolts (17) to 130 ± 7 N·m (96 ± 5 lb ft).

21. Wait 45 minutes, then remove bolts (17) and retainer (18) to add shims (20) 22. Determine the required number of shims (20) to obtain 2.30 ± 0.25 mm (0.10 ± 0.01 inch) of deflection in spring (21). Use a depth micrometer to obtain the distance from the end of shaft assembly (16) to the flat surface on spacer (19).

23. Subtract 2.30 ± 0.25 mm (0.10 ± 0.01 inch) from the dimension that was measured in Step 15. The calculated dimension is the thickness of shims (20).

24. Install shims (20), retainer (18), and bolts (17).

25. Tighten bolts (17) to a torque of 130 ± 7 N·m (96 ± 5 lb ft).

26. Tighten bolts (17) again to a torque of 130 ± 7 N·m (96 ± 5 lb ft).
