Suspensions
REAR WHEEL AXLE
•
Use a dial gauge to check the wheel
axle eccentricity (1). Replace the
wheel axle if the eccentricity exceeds
the limit value (1).
Characteristic
Maximum eccentricity:
0.25 mm (0.0098 in)
REAR WHEEL RIM
•
Using a dial gauge, check that the ra-
dial (A) and the axial eccentricity (B) of
the rim (2) do not exceed the limit val-
ue.
An excessive eccentricity is usually caused by
worn or damaged bearings. Replace the rim (2) if
after replacing the bearings, the value is not within
the specified limit.
Characteristic
Maximum radial and axial eccentricity:
0.8 mm (0.031 in)
FINAL DRIVE UNIT BEARINGS
Carry out the check with the bearings fitted on the
final drive unit.
ROTATION CHECK
•
Remove the left spacer (3).
•
Remove the right spacer (4).
•
Manually rotate the inside ring of each
bearing. Rotation must be constant,
smooth and noiseless.
If one or both bearings do not fall within the control
parameters:
•
Replace both bearings of the final drive
unit.
