For proper installation, use the following
procedure:
1. Using the appropriate stud template
(see chart), mark the desired stud
pattern to be used.
2. Using the proper-sized stud hole
drill bit, drill out the stud holes.
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...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 having
to turn the snowmobile around by hand.
This feature, under most situations, should
not be used to free a stuck snowmobile as
it will tend to dig the skis deeper into the
snow. Always use minimal speed when
operating in reverse and come to a com-
plete stop before shifting from either for-
ward to reverse or reverse to forward.
Shifting Into Reverse
741-438A
NOTE: Correct drive belt tension
(deflection)
is
important
for
the
reverse function to operate properly. If
the belt is too tight, difficulty in
engaging reverse will be experienced.
1. Always warm up the engine for 2-3
minutes prior to shifting into reverse.
2. Shift only with the engine at idle
RPM and the snowmobile com-
pletely stopped. The reverse func-
tion will not engage if engine is
above idle RPM.
NOTE: The system will not shift
until the button is released.

! 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.
