WARNING
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
As the V-belt wears, the position of the V-
belt will change. If the V-belt position is
out of specification, it must be adjusted to
ensure proper clutch performance.
Have a Yamaha dealer make this adjust-
ment.
1. Place the snowmobile on a level surface
and apply the parking brake.
2. Remove the shroud and the left side cov-
er (RST1NTF / RST1NTFY), or open the
shroud (RST9N), and then remove the
drive guard. (See page 26 for drive guard
removal procedures.)
3. Remove the screws and the bolts, and
then pull the left lower cover outward to
remove it (RST1NTF / RST1NTFY).
