● Coming in contact with the rotating V-
belt or clutch parts can cause severe in-
jury or death. Never run the engine with
the drive guard removed.
● Make sure that the drive guard is tight-

injury or death from a broken V-belt or
other part should it come off the snow-
mobile while it is in operation.

To replace and adjust the V-belt
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
ECS00511
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 en-
sure 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, and then remove the drive guard.
(See pages 18 and 44 for removal proce-
dures.)
3. Rotate the secondary sliding sheave
clockwise and push it so that it separates
from the secondary fixed sheave.
