SWINGARM BEARINGS
Carry out the check with the bearings fitted on the swingarm.
ROTATION CHECK
•
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 swingarm bearings.
RADIAL AND AXIAL CLEARANCE CHECK
•
Check the radial and axial clearance.
Axial clearance: a minimum axial clearance is allowed.
Radial clearance: none.
If one or both bearings do not fall within the control parameters:
•
Replace both swingarm bearings.
ALWAYS REPLACE BOTH BEARINGS.
ALWAYS REPLACE THE BEARINGS WITH OTHERS OF THE SAME TYPE.
SWINGARM SEALS
•
Check that the gaskets are in good conditions; replace them if they show signs of damage
or excessive wear.
ALWAYS REPLACE BOTH GASKETS.
ALWAYS REPLACE THE GASKETS WITH OTHERS OF THE SAME TYPE.
SWINGARM PIN
•
Use a dial gauge to check the swing-
arm pin eccentricity. If the eccentricity
exceeds the limit value, replace the
swingarm pin.
Maximum eccentricity: 0.3 mm (0.012 in)
