MAINTENANCE WORK ON CHASSIS AND ENGINE
»
Before remounting the front wheel, clean and grease the shaft seal rings [A]
and the bearing surface [B] of the distance bushings and mount the distance
bushing
Dismounting and mounting the rear wheel
Jack the motorcycle up on its frame so that the rear wheel no longer touches
the ground.
Remove the collar nut [4], remove the chain tensioner [5] and pull out the
wheel spindle [6] until you can push the rear wheel forwards.
Take the chain off the rear sprocket, pull out the wheel spindle and carefully
remove the rear wheel from the swing arm.
– 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.
If the axle is dismounted, clean the thread of the wheel spindle and col-
lar nut thoroughly and apply a new coat of grease to prevent the thread
from jamming.

To install the front wheel, lift it into the fork, position and mount the axle
shaft [1]. Mount the collar nut [2], tighten the clamping screws [3] on the
right fork leg axle passage to prevent the axle shaft from turning and tighten
the collar nut to 40 Nm (30ft.lb).
Loosen the clamp screws on the right fork leg. Take the motorcycle down from
its stand. Press the front wheel brakes and push down on the fork a few times
vigorously so that the fork legs come into alignment.
Only after this has been accomplished, tighten the clamp screws on both fork
legs with 15 Nm(7 ft. lbs).
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,
otherwise the braking effect would be strongly reduced.
