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 meas-
uring them with slide callipers across the whole
clutch hub. If the thickness is below 60 mm, the
clutch must be replaced. See figure 19.
