MAINTENANCE WORK ON CHASSIS AND ENGINE
»
Removing and mounting the front wheel
Jack the motorcycle up by the frame so that the front wheel is suspended
above the ground.
Undo the hexagon nut
[1]
and remove it together with the washer.
Hold the front wheel and pull out the wheel spindle
[2]
.
Carefully take the front wheel out of the fork.
– Do not operate the hand brake when the front wheel has been dismounted.
– Make sure the brake disc is always on top when you lay down the wheel,
otherwise the brake disc can be damaged.
Lift the front wheel into the fork and correctly position it.
Mount the wheel spindle
[2]
.
Mount the washer and the hexagon nut
[1]
and tighten 40 Nm.
Put the motorcycle back on the ground and operate the front wheel brake until
the working point is reached.
– If you don’t happen to have a torque wrench at hand, make sure you have
the tightening torque corrected by a KTM dealer as soon as possible. A
loose axle may lead to an unstable driving behavior of your motorcycle.
– After mounting the front wheel, keep operating the hand brake until the
pressure point returns.
– It is very important to keep the brake disk free from oil and fatty matters,
eitherwise the braking effects would be strongly reduced.
Removing and mounting the rear wheel
Prop up the motorcycle under the frame.
Remove hexagon nut
[3]
on the wheel spindle and disk.
Hold the rear wheel and remove the wheel spindle.
Move the rear wheel forwards, remove chain, lift the rear wheel out of the
swinging fork and remove the brake anchor.
– Do not operate the rear brake when the rear wheel has been dismounted.
– Make sure the brake disc is always on top when you lay down the wheel,
otherwise the brake disc can be damaged (50 SX).
To mount the wheel reverse the procedure described above.
Always hook the brake backing plate into the swing arm support.
Before tightening the hexagon nut of the wheel spindle, ensure that the
supporting plates
[4]
are resting against the swing arm. Additionally, check
that the rear wheel is aligned with the front wheel.
Tighten the hexagon nut to 40 Nm.
– If you don’t happen to have a torque wrench at hand, make sure you have
the tightening torque corrected by a KTM dealer as soon as possible. A
loose axle may lead to an unstable driving behavior of your motorcycle.
– After mounting the rear wheel, keep operating the rear brake until the pres-
sure point returns (50 SX).
– It is very important to keep the brake disk free from oil and fatty matters,
otherwise the braking effects would be strongly reduced (50 SX).
