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 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 30 and 63 for removal proce-
dures.)
3. Rotate the secondary sliding sheave
clockwise and push it so that it separates
from the secondary fixed sheave.
