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
To install the front wheel, lift it into the fork, position and mount the axle
shaft. Mount the collar nut [5], tighten the clamping screws [6] 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 BEHAV-
IOR 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.
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 [1], remove the chain tensioner [2] and pull out the
wheel spindle [3] 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 COLLAR NUT THOROUGHLY AND APPLY A NEW COAT OF GREASE TO PRE-
VENT THE THREAD FROM JAMMING.
The rear wheel is remounted in the reverse order. Before tightening the col-
lar nut to 80 Nm (60 ft.lb), 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 AXLE MAY LEAD TO AN UNSTABLE DRIVING BEHAV-
IOR OF YOUR MOTORCYCLE.
– AFTER MOUNTING THE REAR WHEEL, KEEP OPERATING THE REAR BRAKE UNTIL
THE PRESSURE POINT RETURNS.
– IT IS VERY IMPORTANT TO KEEP THE BRAKE DISK FREE FROM OIL AND FATTY
MATTERS, OTHERWISE THE BRAKING EFFECTS WOULD BE STRONGLY REDUCED.
– TIGHTEN THE COLLAR NUT WITH THE REQUIRED TORQUE. A LOOSE WHEEL
SPINDLE MAY LEAD TO AN UNSTABLE BEHAVIOR OF YOUR MOTORCYCLE.
