7.25 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.

7.26 Dismantling and assembling the

clutch drum and drive shaft
