7.3.3 DISASSEMBLING THE WHEEL
Carefully read 0.4.1 (PRECAUTIONS AND GENERAL
INFORMATIONS).
• Remove the wheel, see 7.3.1 (REMOVING THE
WHOLE WHEEL). .
• Use a cloth to clean both sides of the hub.
• Remove the right spacer (1).
When reassembling, the right spacer (1) must be po-
sitioned with the side featuring the greatest diameter
facing the fork's right leg.
• Remove the seal (2).
• Remove the snap ring (3).
• Use a special extractor to extract the left bearing (4) fol-
low~d
bytherightbearing (5).
The bearings must be checked and, if necessary,
changed every time they are disassembled.
• Retrieve the inner spacer (6).
• Thoroughly clean the inside of the hub.
NOTE
Wash all the components with a clean deter-
gent.
When reassembling, use a drift with the same diame-
ter as the outer race to insert the bearings.
Do not strike the balls and/or the inner race.
Make sure the right bearing (5) is perfectly in contact.
7.3.4 CHECKING THE COMPONENTS
Make sure that all the components are intact, particu-
larly the following.
BEARINGS, SEALS, WHEEL PIN AND RIM, see 7.2.3
(CHECKING THE COMPONENTS).
FLEXIBLE COUPLINGS
• Make sure the rubber elements (7) of the flexible cou-
plings are not damaged and/or feature excessive wear.
Where necessary, replace the rubber elements (7).
• Fit the whole final drive unit (8) on the wheel, turn the
sprocket (9) by hand both ways and check the slack be-
tween the flexible coupling rubber elements (7) and the
flexible coupling holders (10).
If slack is excessive, all the rubber elements (7) must
be replaced.
SPROCKET
• Check the state of the sprocket's (9) and pinion's teeth.
If there are signs of excessive wear, replace the
sprocket, pinion and driving chain, see 7.3.2 (DISAS-
SEMBLING THE FINAL DRIVE UNIT) and 7.11 (DIS-
ASSEMBLING THE DRIVING CHAIN).
To avoid the untimely wear of the new components,
crown, pinion and drive chain must be replaced all to-
ge~her.

TYRE
• Check the state of the tyre, see 2.36 (TYRES) and 7.4
