Centrifugal clutch, drive shaft
Separate the engine unit the clutch housing (see
section 10).
Remove the drive shaft with clutch drum from the drive
shaft tube.
Remove the centrifugal clutch from the crankshaft (left-
hand thread).
The clutch may be fitted so tightly to the crankshaft that
it is difficult to remove merely by striking the socket
wrench with a hammer against the compression resis-
tance of the engine.
In such cases there is a remedy:
Remove the starter and fit holdfast No 502 50 25-01 to
the flywheel (se section 5).
Inspection
Inspect the clutch centre spokes and the centrifugal
weights for wear.
The weights should have a minimum of 1 mm metal at
the most worn point on the contact surface.
In the event of replacement, all weights must be re-
placed at the same time.
Check that the clutch spring is not broken or discoloured
by running hot. If it is, change the spring.
Inspect the drive shaft for wear at its connection to the
angle gear and check that the thrust bearing in the
clutch drum is in perfect condition.
Change any worn or damaged parts.
Replacement of clutch
spring
The clutch spring can easily be changed using special
pliers No 502 50 49-01
