3. Push the stud through the hole from
inside the track; then place the
domed support plate and lock nut on
the exposed stud.
4. Using a wrench to secure the stud,
tighten the lock nut on the exposed stud.
It is also recommended that whenever
studs are installed on a track, carbide
wear bars should be installed on the skis.
Carbide wear bars complement the track
studs to balance steering control under
these conditions. The length of the car-
bide on the wear bars should be propor-
tionate to the number of track studs (i.e.,
small number of track studs = short
length of carbide and many track studs =
long length of carbide). The proper pro-
portion between the number of studs and
carbide length on the wear bar will main-
tain steering balance.
Reverse Operation
The engine 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.
Shifting Into Reverse
ONS-314
1. Always warm up the engine for 2-3
minutes prior to shifting into reverse.
The reverse function is canceled when
engine temperature is below or above
normal operating range.
2. Shift only with the engine at idle
RPM and the snowmobile com-
pletely stopped.
3. If attempting to shift into reverse at
too high engine RPM (above 3000
RPM), the reverse function will be
canceled. This indicates the reverse
switch button was pressed at too high
RPM. The operator must reduce
engine RPM below 3000 and press
the button a second time.
4. Upon pressing the reverse switch
button, the reverse function will
make up to three attempts to engage
into reverse. If the function is not
completed after the third attempt,
the engine will shut down.
! WARNING
Never rotate a damaged track under
power and never perform track mea-
surements, adjustments, and/or
maintenance with the engine running.
! WARNING
Always balance the snowmobile with
the proper proportion between the
number of studs and carbide length
on the wear bars. Do not “over drive”
conditions; use common sense in all
operating conditions.
CAUTION
Do not use studs that are more than
9.525 mm (0.375 in.) longer than the
track lug height.
! WARNING
Do not operate a snowmobile with
loose studs as they may be thrown
from the track. Always use a shielded
safety stand whenever performing
any maintenance or adjustments.
! WARNING
DO NOT stand behind the snowmo-
bile or near the rotating track. NEVER
run the track at high speed when the
track is suspended.
CAUTION
Never shift into reverse while the
snowmobile is moving forward as it
is hard on the driven clutch.
