Illustration 7 g00938190
Install spacer (22), spring (21), and spacer (19) .
Determine the required number of shims (20) to obtain 2.30 0.25 mm (0.091 0.010 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) .
Subtract 2.30 0.25 mm (0.091 0.010 inch) from the dimension that was measured in Step 12. The calculated dimension is the thickness of shims (20) .Note: Do not install shims (20) at this time.
Attach Tooling (B) and a suitable lifting device to shaft assembly (16). The weight of shaft assembly (16) is approximately 32 kg (70 lb).
