When operating the snowmobile at high
altitudes, it may be necessary to change
certain component parts of the drive
clutch and/or the driven clutch. See an
authorized Yamaha Snowmobile dealer
for further information.
CAUTION
DO NOT attempt to service the drive
clutch and driven clutch. The drive
clutch and driven clutch must be ser-
viced by an authorized Yamaha
Snowmobile dealer only.
Drive Clutch/Driven Clutch
Alignment
The alignment between the drive clutch
and driven clutch is set at the factory. Nor-
mally, no adjustment is necessary as long
as neither the drive clutch nor the driven
clutch is removed or disassembled. How-
ever, if premature drive belt wear is expe-
rienced or if the drive belt turns over, the
drive clutch/driven clutch alignment must
be checked. Take the snowmobile to an
authorized Yamaha Snowmobile dealer
for this service. If not under warranty, this
service is at the discretion and expense of
the snowmobile owner.
Fuel Pump
The fuel pump is designed to provide
adequate amount of gas to the injectors at
all throttle settings. If a fuel delivery
problem is suspected, take the snowmo-
bile to an authorized Yamaha Snowmo-
bile dealer. If not under warranty, this
service is at the discretion and expense of
the snowmobile owner.
Track/Track Studs
Accelerated wear strip and track clip
wear caused by operating on ice or hard-
packed snow conditions is NOT covered
under Yamaha warranty policy.
NOTE: If regularly operating on
ice or hard-packed snow condi-
tions, Performance Wear Strips
may be installed at the expense of
the snowmobile owner.
In general, track life will be shortened
when studs are installed. Drilling stud
holes into the drive track will cut the
internal fibers weakening the track.
Avoid spinning the drive track. Studs
may catch on an object and pull out of the
track leaving tears and damage around
the already weakened area. To minimize
possible damage, consult your stud man-
ufacturer for installation and stud pattern
recommendations. Yamaha does not rec-
ommend studding a track.
Paddle Track (On Equipped
Models)
These models are equipped with a Power
Claw style track which is specially
designed for use in powder snow riding
conditions. When the Power Claw track
is operated in hard-packed snow condi-
tions, it will run slightly slower than a
standard track and it will accelerate wear
strip wear. To decrease the amount of
wear strip wear, slower speeds must be
maintained when operating on hard-
packed trails. Accelerated wear strip
wear caused by operating a Power Claw
track on hard-packed snow conditions is
NOT covered under Yamaha warranty
policy.
NOTE: If operating on ice or hard-
packed snow conditions, it is rec-
ommended that Ice Scratchers be
installed to reduce wear strip wear
and engine overheating.
Reverse Operation
The electrical reverse function offers the
operator the convenience of being able to
back up the snowmobile rather than hav-
ing to turn the snowmobile around by
hand. This feature, under most situations,
should not be used to free a stuck snow-
mobile as it will tend to dig the skis
deeper into the snow. Always use mini-
mal speed when operating in reverse and
come to a complete stop before shifting
from either forward to reverse or reverse
to forward.
