FRONT WHEEL COMPONENT INSPECTION

WARNING
Check that all components are in perfect
condition. Inspect the following components
with special care.
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
Check spindle (2) run-out using a dial gauge. Replace the
spindle (2) when run-out exceeds the maximum limit
allowed.
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 check run-out again.
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 2.19.1.
