7.9.2 CHECKING THE COMPONENTS

a
CAUTION
Make sure that all the components are intact, particu-

N
Manually rotate the rollers (1) of each single bearing.
The rotation must be regular, smooth and noiseless.
If one or both bearings is/are not in compliance with the
check parameters:
~ Remove the seal (2).
N
Wash the bearings with a clean detergent.

If one or both bearings is/are not in compliance with the
check parameters:
N
Change the rear fork bearings, see 7.9.6 (DISASSEM-

a
WARNING
Always change both bearings.
Always replace the bearings with bearings of the
same type.
CHECKING THE END AND RADIAL PLAY
N
Check the radial play and the end play.
End play: a minimum end play is allowed.
Radial play: none.
If one or both bearings is/are not in compliance with the
