Careful adjustment of the drive pinion and ring gear is important to guarantee a long service life and quiet running for the final drive. This is why drive pinions and ring gears are matched during production and checked on special testing machines for the most favorable surface appearance and low noise levels in both directions of rotation. The position of quietest running is determined by moving the drive pinion in an axial direction, keeping the ring gear within specified backlash tolerances.
The deviation "r" from the master gaube "Ro" is measured and inscribed on the outside periphery of the ring gear belonging to a pinion/ring gear set supplied as a spare part. Each set (drive pin ion and ring gear) may only be replaced together.
