Dismounting and mounting the rear wheel
NOTE FOR MODELS WITH ABS (ANTILOCK BRAKE SYSTEM):
The ABS sensor
[6]
can be removed to make it easier to dismount and mount the rear wheel.
Loosen the HH screw
[7]
and pull out the ABS sensor. When remounting, apply Loctite 243
(screw retainer) to the thread, mount the screw and tighten to 8 Nm.
Set the motorcycle on the center stand to keep the rear wheel from touching the ground.
Unscrew the collar nut
[1]
, remove the chain tensioner
[2]
, hold on to the rear wheel while
you pull out the axle passage
[3]
. Push the rear wheel as far to the front as possible, take
the chain off of the rear sprocket and lay it on the rear sprocket guard. Carefully lift the rear
wheel out of the swing arm.
– Do not operate the rear brake when the rear wheel has been dismounted.
– When you lay the wheel down, make sure the brake disk and (for models with ABS) the
ABS sensor wheel are not damaged.
– If the axle is dismounted, clean the thread of the wheel spindle and collar nut thoroughly
and apply a new coat of grease (Motorex Long Term 2000) to prevent the thread from
jamming.
– Models with ABS: when you dismount and mount the rear wheel, make sure that
you do not damage the ABS sensor [6] and do not bend the ABS sensor wheel.
Before remounting the rear wheel, clean and grease the bearing surface of the bushings
[4]
and the shaft seal ring
[5]
.
The rear wheel is remounted in reverse order. Pay attention to the same mounting position
of the axle passage and the chain tensioner and make sure the noses
[A]
point to the front.
Before tightening the collar nut to 90 Nm, push the rear wheel forwards so that the chain
tensioners lie on the tension screws.
– If you don’t happen to have a torque wrench at hand, make sure you have the tighten-
ing torque corrected by a KTM dealer as soon as possible. A loose wheel spindle may
lead to an unstable driving behavior of your motorcycle.
– After mounting the rear wheel, keep operating the footbrake until the pressure point returns.
– It is very important to keep the brake disk free from oil and grease, otherwise the brak-
ing effect would be strongly reduced.
