Fig. 7 Pressing wheel bearing Into wheel bearing housing with 75 mm diameter

Note: Larger inside diameter of wheel bearing faces wheel hub.





Fig. 8 Pressing wheel bearing Into wheel bearing housing with 82 mm diameter

Note: Larger inside diameter of wheel bearing faces wheel hub.





Fig. 9 Pressing wheel hub Into wheel bearing with 75 mm diameter

Note: Make sure that dead weight of wheel bearing housing does not press on wheel hub. This can damage wheel bearing.

^ When pressing in, pressure piece (VW519) may only lie against bearing inner ring.

Note: While pressing in wheel bearing housing, must be kept as horizontal as possible. Otherwise, wheel hub would tilt in wheel bearing, causing early damage to bearing.
