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.
Drive Clutch/Driven Clutch
Alignment
The alignment between the drive clutch
and driven clutch is set at the factory.
Normally, no adjustment is necessary as
long as neither the drive clutch nor the
driven clutch is removed or disassem-
bled. However, if premature drive belt
wear is experienced 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 dis-
cretion 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.
Shock Absorbers
(Rebuildable Gas)
Each shock absorber should be visibly
checked weekly for fluid leakage, cracks or
breaks in the body/reservoir, or a bent shaft.
If any one of these conditions is detected,
replacement or service is necessary. Take the
snowmobile to an authorized Yamaha
Snowmobile dealer for this service. If not
under warranty, this service is at the discre-
tion and expense of the snowmobile owner.
NOTE: When the snowmobile is
operated in extremely cold
weather (-23°C/-10°F or colder), a
small amount of leakage may be
present. Unless the leakage is
excessive, replacement is not nec-
essary.
NOTE: The frequency of servic-
ing rebuildable shock absorbers
will vary according to the types of
conditions and terrain the snow-
mobile has been subjected to. If
riding quality deteriorates (or
seems to be deteriorating), take the
snowmobile to an authorized
Yamaha Snowmobile dealer for
shock absorber evaluation and/or
servicing. This service is at the dis-
cretion and expense of the snow-
mobile 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.
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.
