Wheels overhauling

Check the wear state of the hub bearings. In case of excessive clearance (radial
and axial), operate as follows:
- lay the hub on a flat holder with hole, allowing for the passage of the removed
bearing;
- use a hammer and a pin to exercise pressure only on the bearing inner ring
(see figure) up to its removal;
- continuosly change the pressure position so to get an extraction as regular as
possible;
- extract the spacer and perform the same operations for the other bearing.
Removed bearings must not be reassembled.
When reassembling new bearings checl the seat. It must be clean and without
grooves or scatches. Grease the seat before fitting the bearing, then put it in the seat
using a proper tubolar pad, exercising pressure only on the bearing outer ring uo to
complete inserting. Place the spacer and the proceed with the placing of the other
bearing. Check their alignement by placing the wheel pin.
After every intervention on wheels their balancing is advisable.
