MAINTENANCE WORK ON CHASSIS AND ENGINE
»
Checking rubber ring on the WP rear shock absorber
A rubber ring mounted on the rear shock absorber serves as a vibration damper.
This ring gets pressed together with time and loses its shock absorbing
function.
Measure the distance between the two discs at various points around their
circumferences. The space should be at least 2.5 mm (0,1 in) wide. Have
the rubber ring replaced by an KTM dealer when compaction due to wear has
exceeded this lower limit.
NOT REPLACING THE RUBBER RING IN TIME CAN RESULT IN DAMAGE TO THE
REAR SHOCK ABSORBER.
THE DAMPING UNIT OF THE SHOCK ABSORBER IS FILLED WITH HIGH COM-
PRESSED NITROGEN. NEVER TRY TO TAKE THE SHOCK ABSORBER APART OR TO
DO ANY MAINTENANCE WORK YOURSELF. SEVERE INJURIES COULD BE THE
RESULT.
Lubricate rear suspension linkage
The bearings in the link lever must be greased in regular intervals. For this
purpose, a lubricating nipple
[1]
is mounted on the link lever.
AFTER EACH TIME THE MOTORCYCLE IS WASHED, IT IS ESPECIALY IMPORTANT
TO GREASE THE LUBRICATING NIPPLE TO PUSH ANY WATER OUT OF THE
BEARINGS.
Checking chain tension
To check, place the motorcycle on the side stand.
Switch transmission to neutral.
Push the chain upwards appr. 30 mm (1,2 in) from the end of the chain
sliding component until the upper part of the chain is tensioned (see
illustration)
Now, the distance
[A]
between chain and swingarm should be 0 mm. The
upper part of the chain
[B]
must be tight (see illustration).
Correct chain tension, if necessary!
– IF CHAIN TENSION IS TOO HIGH, PARTS WITHIN THE SECONDARY TRANSMIS-
SION (CHAIN, SPROCKETS, DRIVE ASSEMBLY AND REAR WHEEL BEARINGS)
WILL BE SUBJECTED TO UNNECESSARY STRESS, RESULTING IN PREMATURE
WEAR AND EVEN CHAIN BREAKAGE.
– TOO MUCH SLACK IN THE CHAIN, ON THE OTHER HAND, CAN RESULT IN THE
CHAIN JUMPING OFF THE SPROCKETS. IF THIS HAPPENS, THE CHAIN COULD
ALSO BLOCK THE REAR WHEEL OR DAMAGE THE ENGINE.
– IN EITHER CASE THE OPERATOR IS LIKELY TO LOSE CONTROL OF THE MOTOR-
CYCLE.
