Standard-Lug Track
Accelerated wear strip wear caused by
operating on hard-packed snow condi-
tions is NOT covered under Arctic Cat
Inc. warranty policy.
Track Studs
NOTE: Stud or hooker plate instal-
lation will void track and tunnel war-
ranty.
NOTE: Stud installation can be per-
formed by the snowmobile owner if
qualified to do so. If the owner does
not feel qualified, take the snowmo-
bile to an authorized Arctic Cat Snow-
mobile dealer for this service. This
service is at the discretion and
expense of the snowmobile owner.
NOTE: To prevent tunnel damage
from the studs, Tunnel Protector Kit
(p/n 4639-771) for the Bearcat 570/
T570 models or (p/n 5639-143) for the
Bearcat Z1 XT model must be
installed.
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.
CAUTION
If installing studs on standard
Bearcat 570 model with a single-ply
track, studs with a head diameter of
at least 28.6 mm (1.125 in.) must be
used.
! WARNING
When installing studs on a single-ply
track, it is important to use Arctic
Cat-approved studs (proper head
diameter). If approved studs (proper
head diameter) are not used, studs
could tear free of the track causing
possible injury or even death. Con-
sult an authorized Arctic Cat Snow-
mobile dealer for information.

! 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 per-
forming any maintenance or adjust-
ments.
! 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.
