CHECKING THE FRONT WHEEL COMPONENTS

WARNING
Ensure that all components are intact and
especially the following ones.
BEARINGS
Manually turn the inner ring (1); it should turn smoothly with
no noise and/or hard spots.
No axial play should be noticed.
Faulty bearings should be changed.
SEALS
Check that all seals are intact; change them if they are
damaged or worn.
WHEEL SHAFT
Using a dial gauge, check shaft runout (2). If runout exceeds
the limit, change the shaft (2). Maximum runout: 0.25 mm.
WHEEL RIM
Using a dial gauge, check that rim (3) radial (A) and axial
(B) runout does not exceed the specified limit. Excessive
runout is usually due to worn or damaged bearings. If value
still exceeds the specified limit after replacing the bearings,
change the rim (3). Maximum radial and axial runout: 2 mm.
Tyre
Check tyre condition, see 2.19.1.
