4 STROKES
DISASSEMBLING AND ASSEMBLING REAR WHEEL (SMM)
Position the motorcycle with the frame cradle on a stand to keep the
rear wheel off the ground. Cut the safety wiring (1), remove the clip (2)
and loosen the M50x1.5 wheel nut (3). Be careful of the conical shim (4)
located between the nut and rim. Carefully remove the wheel.
WARNING
- WHEN THE WHEEL NUT IS DISASSEMBLED, CLEAN THE THREADING OF BOTH
THE SHAFT AND THE NUT AND RE-GREASE THEM TO PREVENT THE THREAD-
ING FROM SEIZING.
Perform the operation in the reverse order to assemble the M50x1.5
wheel nut, tightening it by 180 Nm. Reassemble the clip (2) and re-do
the safety wiring (1).
- DO NOT FORGET TO DO THE SAFETY WIRING AT THE ENDS OF THE CLIP
- IF YOU DO NOT HAVE A TORQUE WRENCH FOR ASSEMBLING, HAVE THE
TIGHTENING TORQUE CHECKED BY A SPECIALISED TM WORKSHOP AS SOON
AS POSSIBLE. AN INCORRECTLY TIGHTENED WHEEL PIN MAY MAKE THE
MOTORCYCLE UNSTABLE.
- AFTER HAVING ASSEMBLED THE REAR WHEEL, ACTIVATE THE FRONT BRAKE
PEDAL REPEATEDLY AND MAKE THE PADS ADHERE TO THE DISC. CHECK THE
BRAKE FLUID LEVEL.
- THE BRAKE DISC MUST ALWAYS BE FREE OF OIL AND GREASE TO AVOID
SIGNIFICANTLY REDUCING THE BRAKING EFFECT.
CHECKING SPOKE TENSION
Correct spoke tension is important for the stability of the wheel and for
road safety. An insufficiently taut spoke makes the wheel unstable and
will loosen the other spokes in a short time. Check spoke tension on a
regular basis, especially on new motorcycles. To this end, briefly hit every
spoke with the tip of a screwdriver (see photo); the spoke should produce
a clear sound. Hollow sounds mean that the spokes are loose. In this case,
refer to a specialised workshop to adjust the spokes and centre the wheel.
- IF YOU CONTINUE TRAVELLING WITH INSUFFICIENTLY TAUT SPOKES THEY
MAY SNAP, CAUSING INSTABILITY PROBLEMS.
- EXCESSIVELY TIGHT SPOKES MAY SNAP DUE TO LOCAL OVERLOADING.
