DISASSEMBLING AND ASSEMBLING FRONT WHEEL
- Position the motorcycle with the frame cradle on a stand to keep the
front wheel off the ground.
- Loosen the aluminum flanged screw (1), loosen fixing screws (2) and (3)
on the left and right fork feet and finish unscrewing the flanged screw
(1).
- Hold the front wheel still and slide out the wheel pin (4).
If necessary, help the pin out by tapping the threaded end of the pin
with a mallet (hammer with plastic head).
Alternatively, use a normal hammer, placing a pin punch in between.
WARNING
Never use the hammer directly on the pin. It could cause irreversible
damage.
- Carefully remove the front wheel from the fork.
WARNING
- Never operate the brake lever when the front wheel has been removed.
- Always lay the wheel flat with the brake disc upwards to avoid damaging
it.
- To re-fit the front wheel, carefully insert it in the fork, ensuring that
you correctly insert the disc between the brake pads without damaging
them. With the wheel correctly positioned, insert the wheel pin (4),
positioning the spacer (5) on the left-hand part of the wheel.
- Screw in and temporarily tighten the flanged screw (1) until the wheel
shim is locked. Tighten the locking screws (2) on the right-hand fork foot
to prevent the wheel pin from turning and tighten the flanged screw
to 40 Nm.
- Tighten the locking screws (3) on the left-hand fork foot to 12 Nm.
- Loosen the locking screws (2) on the right-hand foot again and remove
the motorcycle from the stand. Operate the front brake and force the
fork down several times to align its tubes.
- Definitively tighten the locking screws (2) on the right-hand fork foot
to 12 Nm.
DANGER
- IF FOR ASSEMBLY OPERATIONS YOU DO NOT HAVE A TORQUE
WRENCH, GET THE TIGHTENING TORQUE CHECKED AS SOON AS
POSSIBLE AT A SPECIALIZED TM WORKSHOP. AN INCORRECTLY
TIGHTENED WHEEL PIN MAY MAKE THE MOTORCYCLE UNSTABLE.
- AFTER FITTING THE FRONT WHEEL, REPEATEDLY OPERATE THE BRAKE
LEVER TO MAKE THE PADS ADHERE TO THE DISC AGAIN AND CHECK
THE BRAKE FLUID LEVEL.
- ALWAYS KEEP THE BRAKE DISC FREE OF OIL AND GREASE. OTHERWISE
THE BRAKING EFFECT WOULD BE SIGNIFICANTLY REDUCED.
