Track Warranty Guidelines

734-522A

734-522B

734-522C

734-522D

Failure Mode

Description

Cause

Warranty

Delamination (A) Condition in which the track fabric cleanly

separates or spreads apart from the rubber.

Result of poor adhesion between fabric and rubber mate-
rial

Covered

Tread/External
Lug Damage
(B)

Condition in which the lugs are torn,
cracked, worn, or separated.

Most often a result of riding/spinning on rugged terrain...
-rocks,
-jagged ice,
-metal objects,
-gravel roads.
High speed running with poor lubrication may produce
gummy external track lugs leading to separation.

Not Covered

Edge Tearing
(C)

A track failure that occurs along the side of
the track in which tearing occurs either par-
allel or perpendicular to the track edge.

Rods out of center. If a rod is positioned off-center during
track manufacturing, tearing along the side of the track
may occur ± 1/2 in. from the edge.

Covered

Traction Product
and Clip Damage

Cutting that occurs where a stud or pick is
attached to the track. This includes tearing
due to stud pull-through as well as track
clips that are torn off.

Often the result of contact having been made with a solid
or jagged object (e.g. rocks, ice, metal, gravel, etc.).

Not Covered

Internal Lug
Damage

Condition in which internal lugs are torn,
worn, or cracked.

Result of contact being made with a foreign object.

Track derailment can also cause this damage.

Not Covered

Broken Rods/
Missing Clip
(D)

Condition in which tracks are found to have
broken rods. Gummy tread sometimes
accompanies broken rods.

Wear clip and rod section broken out and
missing.

Typically, results from track impacts and overheating.

Overheating of the rod can result from friction buildup due
to poor lubrication or riding at high continuous speeds for
long periods of time in minimal snow conditions.

Gummy tread and brown or dark brown rod color at the
center sometimes accompanies this failure.

Signs of wear strip material melted and sticking to the
edges of the wear clip. Also, wear clips that have started
to turn blue in color from overheating are all signs of oper-
ating the snowmobile on minimal snow.

Not Covered

Large Deformi-
ties of the Track
or Air Bubbles

Condition in which a track has large deformi-
ties which may include air bubbles/pockets/
voids within the track.

Manufacturing flaw.

Covered

Lugs Torn Off
Outer Belt (B)

Condition normally found on deep lug
tracks.

Typically, the result of operating a deep lug track on mini-
mal snow at high rates of speed. This track is designed for
deep snow mountainous areas only.

Not Covered

Track Specifications

Below is a listing of drive tracks for Arctic Cat snow-

mobiles. This chart lists each track with its specifica-

tions. From the information provided in this chart, note

what other tracks can be substituted as a replacement

track if a recommended track isn’t available.

NOTE: On the M-Series, measurement is from the
bottom of the wear strip at the point of the shock
pad on the slide rail. All tracks are 15 in. wide
except for Bearcat 570 (16 in.). All models at 20 lb
except M-Series (10 lb).
