•
Check the radial and axial play.
Axial play: minimal axial play is permitted.
Radial: none.
If one or both bearings are not conformant:
•
Replace both wheel bearings.
ALWAYS REPLACE BOTH BEARINGS.
ALWAYS REPLACE THE BEARINGS WITH COMPONENTS OF THE SAME TYPE.
SEALS
•
Check the condition of the seals; replace if damaged or excessively worn.
ALWAYS REPLACE BOTH SEALS TOGETHER.
ALWAYS REPLACE THE SEALS WITH COMPONENTS OF THE SAME TYPE.
WHEEL AXLE
•
Use a dial gauge to check the wheel
axle eccentricity. Replace the wheel
axle if the eccentricity exceeds the limit
value.
Characteristic
Maximum eccentricity:
0.25 mm (0.0098 in)
•
Using a dial gauge, check that the ra-
dial (A) and the axial (B) eccentricities
of the rim do not exceed the limit value.
An excessive eccentricity is usually
caused by worn or damaged bearings.
Replace the rim if, after replacing the
bearings, the value is not within the
specified limit.
Characteristic
Maximum radial and axial eccentricity:
2 mm (0.0079 in)
