7.2. Friction Discs / Clutch Plates
Check the friction discs and the clutch plates every time before driving. If you notice signifi-
cantly worn, distorted or wavy parts, you should replace them immediately and possibly
change the adjustment of the clutch.
In addition it is very important to check the condition of the carrier tabs of
the friction discs (3 carriers per disc). If the carriers have significant play
in the clutch drum (see illustration), replace the friction discs right away.
1.
Remove the clutch cover and note the locations of the different screws.
2.
Hold the clutch in place using the clutch wrench, and release the 22mm clutch nut.
Do not pull the clutch off the eccentric shaft. Leave the small clutch key installed.
3.
Leave the wrench on the clutch and remove the 8 Allen screws (4mm key).
4.
Now only pull the clutch plates and the friction discs off the clutch. Note the position
and sequence of the parts.
5.
Replace the friction discs and/or any wavy pressure or spacer plate.
6.
Put the clutch together again.
7.
Re-assemble the clutch plate with the 8 screws. Hold it in place with the clutch wrench,
and tighten the screws evenly and sufficiently.
8.
Tighten down the clutch nut.
9.
Re-attach the clutch cover.
! If the carriers are worn, they may break in operation without prior notice. This can lead
to damage or total loss of the engine and even personal injury.
! If the friction discs are excessively worn, the weights of the clutch can spread making
contact with the clutch cover. This will damage the clutch and the clutch cover.
7.3. Air Filter Red Filter for Aixro and
Dell’Orto Carburettors
Only use the original air filter provided and keep it clean. Cleaning is especially recom-
mended after “off-road excursions“ and driving in the rain.
1.
Remove the air filter from the carburettor.
2.
Wash the filter carefully with an approved non-inflammable cleaning agent. (e.g. made
by K&N, alternatively also soapsuds).
3.
Dry the filter carefully. Use compressed air if available.
4.
Attach the filter as originally mounted.
! Avoid the risks of fire and explosion. Do not use flammable liquids, fluids, aerosols
(WD40, brake cleaner, etc.) or fuels to clean the air filter.
