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.
ECS00512
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.
