Dismantling - Husqvarna 125C Workshop Manual

4
The centrifugal clutch has the task of transferring the power from the engine to the cutting equipment's
drive axle. As the name implies, it works according to a centrifugal principle.
This means the clutch's friction shoes are thrown outwards towards the clutch drum at a certain engine
speed. When the friction against the drum is sufficiently great it drives the drive shaft at the same speed
as the engine.
Some slipping occurs between the clutch and the clutch drum when accelerating as well as in the
reversed situation when the cutting equipment jams. Thereby preventing abnormal load changes on the
crankshaft.
The engagement speed has been carefully tested so that the engine can idle without the cutting
equipment's drive shaft rotating.
