NOTE
THE TORQUE LIMITER IS EQUIPPED WITH 4 GEARS THAT FUNCTION AS CLUTCH DRIVING
PLATES.
Driven plates consist of 4 Belleville springs with
grooved profiles; this assembly allows transmitting
torques lower than 10 kgm.
In case of incorrect start-up procedures, the torque
limiter prevents any kicks, resulting in inversion of
rotation direction of the crankshaft, which would
impair the engine structure.
The limiter assembly cannot be overhauled. In case of clearly visible irregularities on the toothed discs,
replace the assembly.
Refitting the free wheel
- Make sure the freewheel faying surfaces are in good condition.
- Thoroughly clean the freewheel to remove any LOCTITE left.
- Degrease the threading of the freewheel holes and the fixing screws.
- Apply the recommended product to the end of the screws.
