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 condi-
tions. The length of the carbide on the wear
bars should be proportionate 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 proportion between the number of
studs and carbide length on the wear bar
will maintain 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 and
come to a complete stop before shifting
from either forward 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 experi-
enced.
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 speed
is above idle RPM.
NOTE: The system will not shift
until the button is released.
3. On the Bearcat Z1 XT/F5 LXR/TZ1
models if attempting to shift into
reverse at too high engine RPM
(above idle RPM), the reverse func-
tion will be cancelled and the cool-
ant temperature warning icon will
flash. This indicates the reverse
switch button was pressed at too
high RPM. The operator must
reduce engine RPM below 4000 and
press the button a second time.

! 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.
