9.3.10 Joint type SN9
1. Remove the two clamps (35) that holds the sleeve.
2. Force the rubber sleeve backwards (36) in the direction of the black arrow.
3. Remove the grub screw (37).
4. Move backwards the metallic cover (38) in the direction of the arrow. The bushing
and the pin (39) will then be visible.
5. Beat the pin with care, taking care not to damage the bell (40). Then, if necessary,
the pin and the bushes can be replaced.
6. Pull the sphere in the direction of the black arrow. Since it is integral with the
propeller shaft (41), they’ll both be free of the joint. Then, the hexagonal-head
screws holding the bell to the rotor (or hollow shaft depending on the joint involved)
will be visible at the bottom.
7. Unscrew the screws (42). The bell will be completely free of the rotor (or hollow
shaft, as mentioned above).
8. The rotor will still be anchored to the adapter flange (43), to be released through the
screws (44). Then, the rotor will be completely free, ready for replacement.

IMPORTANT: Bushes increase the life of the system but are integral with the pin,
hence when the pin is replaced they shall always be replaced as well.
