Illustration 34 g01132654
Use Tooling (N) to measure the backlash. Use Tooling (B) in order to adjust spanner nut (6) . The specified backlash is written on bevel gear (22) . This is the minimum backlash that is allowed. Adjust spanner nut (6) in order to achieve the proper backlash. Make sure that spanner nut (6) will allow the lock to be installed.
Illustration 35 g01132651
When the correct backlash has been achieved, tighten spanner nut (8) in order to obtain the specified total rolling torque.
Use the following formula in order to calculate the total rotating torque: Pinion rotating torque x 5.125 N m (3.7800 lb ft) = Total rotating torque
Check the backlash. If the backlash is not correct, adjust spanner nut (6) and spanner nut (8) until the proper backlash and rolling torque is achieved.
