ASSEMBLING AND TESTING THE ENGINE
3.7.1
TESTING THE CLUTCH BELL AND
REPLACING THE SILENT-BLOCK
Before remounting the clutch bell, check
that the sides of the teeth A, which pertain
to primary transmission and B, which per-
tains to the seizing process with the start-up
idler gear, do not have any superficial corro-
sion or are abnormally worn.
Carefully analyse the teeth C, with which
the conductor discs engage, to ensure they
are not cracked or worn.
If any damage is caused, replace the com-
ponents.
Verify the wear-and-tear state of the silent-
blocks 7 as follows. Whilst keeping the too-
thed wheel with the wider diameter in pla-
ce, make the clutch bell 9 turn. Should there
be loosening between the two components,
the silent-blocks must be replaced.
The silent-blocks are replaced by piercing
the riveted part of rivet 8 with a 5 mm tip.
Place the bell in such a way for the retaining
disc to be mounted from above, and then
couple the new silent-blocks to the clutch
bell in the relative housing.
Bring the retaining disc towards the bell and
insert the rivets (5x15) and rivet them.
