Overhauling the front wheel
Wheel bearings
Before checking the dimensions, check the wear on wheel bearings. Check for wear by hand after cleaning and degreasing the
bearings in their seats.
Turn the inner race.
Check the amount of radial and axial play. Excessive play will cause vibration and make the bike unstable; in this case the bearings
must be renewed.
To remove the bearings (5) and the seals (4) from the wheel hub, proceed as follows.
Position a drift (A) against the inner race of the bearing (5).
Tap with a hammer to drive out the bearing (5) and the oil seal (4).
Apply the drift at different points to keep the bearing square during removal.
Important
Once removed, the used bearings and the oil seals must not be refitted.
Before fitting new bearings, check that the housing is clean and free from scoring and damage.
