7.4.4. INSPECTING THE FRONT WHEEL
COMPONENTS
WARNING
Check that all components are in perfect
condition. Pay special attention to the
components listed below.
BEARINGS
Rotate the inner ring (1) manually. The ring should turn
smoothly, with no hardness or noise.
There should be no end float.
Replace any bearings that do not meet the above
requirements.
SEALS
Inspect the seals and replace if damaged or badly worn.
WHEEL SPINDLE
Measure wheel spindle (2) run-out using a dial gauge.
Change the spindle (2) if it exceeds the specified limit.
Wheel spindle run-out limit: 0.25 mm.
WHEEL RIM
Use a dial gauge to ensure that wheel rim (3) radial (A) and
axial (B) run-out does not exceed the maximum limit
allowed.
Exceeding run-out is normally due to worn or damaged
bearings.
Replace the bearings first, then re-check run-out. Replace
the wheel rim (3) if it still exceeds the maximum limit
allowed.
Wheel rim radial and axial run-out limit: 2 mm.
TYRE
Check tyre condition, see 2.17.1.
