7.24 Replacing the clutch drum and
drive shaft
The centrifugal clutch has the task of transferring
the power from the engine to the cutting equip-
ment's drive shaft. 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.
