MAINTENANCE WORK ON CHASSIS AND ENGINE

Dismounting and mounting the rear wheel
To remove the rear wheel, jack the motorcycle up on its frame so that the rear
wheel no longer touches the ground.
Loosen the collar nut [1], remove chain tensioner [2], hold the rear wheel and
pull out the wheel spindle [3] until the rear wheel is free but the brake caliper
support is still held. Push the rear wheel as far forward as possible, take the
chain from the rear sprocket and carefully take the rear wheel out of the swingarm.
– DO NOT OPERATE THE REAR BRAKE WHEN THE REAR WHEEL HAS BEEN DIS-
MOUNTED.
– ALWAYS PLACE THE WHEEL ON THE GROUND WITH THE BRAKE DISC POINT-
ING UPWARDS. OTHERWISE THE BRAKE DISC MAY BE 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.
NOTE: If the rear wheel has been dismounted, you should also check the shock
absorption rubber.
The rear wheel is remounted in reverse order. Before tightening the collar nut
to 80 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 TIGHTENING TORQUE CORRECTED BY A KTM DEALER AS SOON
AS POSSIBLE. A LOOSE WHEEL SPINDLE MAY LEAD TO AN UNSTABLE DRIV-
ING 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 BRAKING EFFECT WOULD BE STRONGLY REDUCED.
Checking the shock absorption rubbers in the rear hub *
LC4 models have a damped rear wheel hub. For this purpose, the engine power
is conveyed from the rear sprocket via 6 shock absorption rubbers [4] to the
rear wheel. These 6 absorption rubbers wear with increasing operation time,
and should be checked for wear whenever the rear wheel is dismounted.
For this purpose, lie the rear wheel on a work bench with the rear sprocket
upwards, and put the wheel spindle in the hub. Now hold the rear wheel firmly
and try to turn the rear sprocket. The rear sprocket may not turn more than
maximum 5 mm (0,2 in) measured on the outside. If the play in the chain
wheel is larger, all 6 shock absorption rubbers are to be replaced.
Check the shock absorption rubbers for signs of damage and dirt.
IF THE SHOCK ABSORPTION RUBBERS ARE NOT REPLACED IN GOOD TIME, THE
REAR SPROCKET CARRIER AND THE REAR HUB WILL BE DAMAGED. ALLWAYS
REPLACE ALL 6 ABSORPTION RUBBERS, NEVER SINGLE RUBBERS.
