GENERAL USEFULL SUGGESTIONS
Directions how to calibrate the
variator
Rollers
Increasing the roller weight, the engine is
compelled to work with a lower number of
revolutions; in this case it is necessary to have
an engine with a strong power couple (power at
low rate).
On the contrary, decreasing the roller weight, the
engine works at a higher number of revolutions;
in this case it is necessary to have an engine with
less power couple and much more acceleration
(power at high rate).
Spring
The pressure spring is vital to give the right
amount of load to the transmission belt which
must be balanced with the force developed by
the centrifuge masses, in relation to the kind of
engine coupling.
If the belt slips, it will be necessary to fit a spring
with more load. Then recalibrate the MULTIVAR.
On the contrary if you fit a spring with too much
load, a lot of engine power will be lost due to
friction and the transmission belt, together with
the pulleys, will be rapidly destroyed.
Transmission Belt
Check the belt every 5000 Km; be sure that it is
of high quality and that there are no damages. lt
must not be worn 1,5 mm more than the A and B
points of the original belt
(Fig.
51).
lf you have any doubt or problems, replace it with
a reinforced Malossi K Belt which you will find with
its code number in the corresponding table of this
sheet or in Malossi Catalogues.

Multivar maintenance
Carry out checks respecting the frequency
indicated in the "Use and maintenance" manual
of the vehicle. In case of a racing use increase the
checking frequency.
Please use exclusively original Malossi spare parts.
Always demand packed and sealed products with
Malossi brand.
Please order parts with the product number that
you find on our catalogue.
Transmission belt
Check that the transmission belt isn't damaged
nor shows abnormal wear.
Pulley check
• Check that the bush does not show neither wear
nor damages.
• Check that the outer diameter of the variator
hub does not show neither wear nor damages.
• Check the wear level of the roller housings as
well as that of the belt contact surfaces.
• Check that rollers aren't damaged nor worn out.
• Check that the variator backplate sliding shoes
are not worn out.
• Check that there isn't too much clearance
between sliders and backplate.
• Check that the oil-seal does not show neither
wear nor damages.
ATTENTION:
IF YOUR VARIATOR FEATURES A SINTERED
SLIDING BUSH, YOU MUST NECESSARILY
