Loosen the spark plug hat and remove the spark
plug, and insert the plastic piston stop

Loosen the clutch using tool 502 54 16-01 and a
suitable socket wrench or combination spanner.
See figure 14. Turn the clutch clockwise to
loosen it.

Carefully loosen the clutch springs with a
screwdriver as outlined in figure 16.
NOTE!

Cleaning and inspection
Clean and check all parts carefully. Parts must
be replaced if cracked or showing signs of
other defects. Always use original spare parts.
Check the thickness of the clutch shoes by
measuring them with slide calipers across the
whole clutch hub. If the thickness is below 65
mm, the entire clutch must be replaced. See
Figure 17.
