Fig. 3 Installing tapered roller bearing inner race
- Install tapered roller bearing inner rase so that the lugs of the inner race engage in the grooves of the opposite inner race (-arrow-) - Fig. 4.

Fig. 4:

Fig. 4 Installation position of tapered roller bearing inner race
- Lug (-arrow-) must engage in groove of the opposite inner race.

Note:
Tapered roller hearings without lugs can also be installed.

Fig. 5 Removing input gear
- Install socket-head fastener without dished washer, shim and axial needle bearing, just far enough so that gap -a- remains between socket-head fastener and tapered roller bearing inner race.
- Gap -a- = approx. 3 mm (0.118 in.)
- Drive out input gear with VW771 as far as the stop of the tapered roller bearing inner race.
- Remove VW 771 and remove input gear.
