WARNING
EWS00411
When installing a new V-belt, make sure
that it is positioned properly. Otherwise,
the V-belt clutch engagement speed will
be changed and the snowmobile may
move unexpectedly when the engine is
started, which could cause an accident.
NOTICE
ECS00510
As the V-belt wears, adjustment may be
necessary. To ensure proper clutch per-
formance, the V-belt position should be
adjusted by adding a spacer on each ad-
justing bolt when the V-belt position
reaches 1.5 mm (0.06 in) below the edge of
the secondary sheave assembly.
Have a Yamaha dealer make this adjust-
ment.
TIP
Apply the parking brake before replacing the
V-belt.
