Fig. 1 Removing small tapered roller bearing outer race from
transmission housing
- Turn webs -A- and -B- out until they sit on outer race within recess in
transmission.
- After removing, check shims for damage.

Note:
Transmission code CXF: use 30-205 thrust pad and VW295 needle
bearing drift. Fig. 2 Installing right tapered roller bearing outer race into
transmission housing
- VW472/1 pressure piece is installed with cone in outer race.

Notes: Fig. 3 Removing right tapered roller bearing inner race
A - Kukko 20/10 two-arm puller, e.g. Kukko 44/2
Pullers with a small spindle diameter, 30-11 thrust pad must be placed
between 447H pressure washer and the puller. Transmission code CX: use 40-105 thrust piece.The differential housing has a notch under the bearing seat to install
puller -A-.
