In order to get to the variator, remove the plastics
around the area indicated by the arrow
following the instruction of the handbook "use
and maintenance".
• Remove the crankcase cover which covers the
variator, loosening the exhaust rear fitting.
• To widen the driven pulleys
(Fig.
two hexagonal screws M6 which fasten the
variator crankcase.
• Unscrew the variator lock nut on the crankshaft
and remove the original variator from
the vehicle.
Proceed as follows on the Malossi variator:
• The grease supplied in the kit must be put in
the internal groove both of the hub and of the
bush
(Fig.
26). The seizure of the bush and
the variator collapse will be occurred If this
direction is not followed.
• Insert the hub into the movable half-pulley,
taking care not to damage the oil-seal rings.
• A plastic bush is supplied in the kit, which is
used to insert the hub into the pulley without
damaging the oil-seal
(Fig.
27). After the hub
is inserted into the bush check that there is
no grease leakage and, if necessary, carefully
remove the grease from the parts around.
• Insert the rollers in their seats.
• Use the original roller guide cover and the
original cursors. If they are excessively worn or
damaged, replace them with original cursors.
• ATTENTION: the introduction of the variator
cover inside the pulley will be lightly forced
where there is contact with the rolls. This is
intentional and it makes extremely silent the
(Fig. 24)
engine at low rpm.
• Clean carefully and remove the grease from the
movable half-pulley using a suitable solvent.
