Fig. 5 Installing separating device
- Install separating device into bearing inner race annular groove -arrow- and tension spindle.
Note: Use commercially available separating device e.g. Kukko 1712.

Fig. 7 Pressing wheel bearing -A- into 75 mm diameter wheel bearing housing
Note: Larger internal diameter of wheel bearing faces wheel hub.
Fig. 8 Pressing wheel bearing -A- into 82 mm diameter wheel bearing housing
Note: Larger internal diameter of wheel bearing faces wheel hub.
Fig. 9 Pressing wheel hub into 75 mm diameter wheel bearing
- When pressing in, the thrust piece VW519 must bear only against inner race.
Notes:
The wheel bearing housing must remain as horizontal as possible when pressing in.
Otherwise the wheel hub will bend in the wheel bearing which will lead to premature wheel bearing damage.
