General

General Notes:
- Careful adjustment of drive pinion and ring gear is essential for long life and quiet running of the final drive. For this reason, drive pinions and ring gears are matched during the production phase and checked with a special gauging machine to ensure proper contact pattern and quiet running in both directions of rotation. The position of the quietest running is determined by moving the drive pinion in an axial direction, with the ring gear being constantly raised out of zero-play meshing to a point where the torsion backlash varies within a specified tolerance.
- The deviation "r" is measured in relation to the master gauge R0 for the drive gear sets supplied as service parts and this value is inscribed on the outer circumference of the ring gear. Each drive gear set-drive pinion and ring gear-must only be replaced together
