30 <strong>Transfer</strong> case 0AQ Oil supply / sealing Shaft oil seal A A press-fitted protective ring on the flange shaft acts as a "deflector ring" and helps to keep dirt and water away from the lip seals during vehicle operation. Oil lip seal In adverse offroad conditions, special demands are made of the sealing of the front axle differential, as well as the rear axle differential and the transfer case flange shafts. This is why shaft oil seals with special dust and moisture seals are used. The sealing of the flange shafts is shown here using the 0AQ transfer case as an example. Shaft oil seal C Shaft oil seal B Protective ring Outer lip seals 363_038 The outer lip seals help to prevent dust and moisture coming into contact with the oil lip seal and its liner.
Service / special tools To avoid having to replace shaft oil seals shafts or flange shafts, the shaft oil seals must be press-fitted more deeply than in series production. 363_047 Service As a result, the lip seal of the shaft oil seal runs on a new liner. This ensures less load on the sensitive lip seal, which, in turn, extends seal life and improves sealing performance.
