● When installing the new V-belt, make
sure that it is positioned properly. Other-
wise, the V-belt clutch engagement
speed will be changed and the snowmo-
bile may move unexpectedly when the
engine is started, which could cause an
accident.
● Have a Yamaha dealer make this adjust-
ment.
CAUTION:
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.
NOTE:
Apply the parking brake before replacing the
V-belt.
1. Remove the shroud and the left side cov-
er, and then remove the drive guard.
(See page 43 for removal procedures.)
2. Rotate the secondary sliding sheave
clockwise and push it so that it separates
from the secondary fixed sheave.
3. Pull the V-belt up over the secondary
fixed sheave.
4. Remove the V-belt from the secondary
sheave assembly and primary sheave
assembly.
