FOREWORD
Congratulations! You have chosen a quality Arctic Cat Snowmobile designed and manufactured to give depend-
able service. Be sure, as the owner/operator of an Arctic Cat Snowmobile, to become thoroughly familiar with its
basic operation, maintenance, and off-season storage procedures. Read this manual and the accompanying Snow-
mobile Safety Handbook before operating the snowmobile to ensure safe and proper use of your new Arctic Cat
Snowmobile. Always operate the snowmobile within your level of skill and current terrain conditions.
The Operator’s Manual, Snowmobile Safety Handbook, and snowmobile decals display the words Warning, Cau-
tion, and Note to emphasize important information. The symbol !WARNING identifies personal safety-
related information. Be sure to follow the directive because it deals with the possibility of severe personal injury or
even death. A CAUTION identifies unsafe practices which may result in snowmobile-related damage. Follow
the directive because it deals with the possibility of damaging part or parts of the snowmobile. The symbol
NOTE: identifies supplementary information worthy of particular attention.
This manual covers operator-related maintenance, operating instructions, and off-season storage instructions. If
major repair or service is ever required, contact an authorized Arctic Cat Snowmobile dealer for professional ser-
vice.
At the time of publication, all information and illustrations were technically correct. Some illustrations used in this
manual are used for clarity purposes only and are not designed to depict actual conditions. Because Arctic Cat Inc.
constantly refines and improves its products, no retroactive obligation is incurred.
This Operator’s Manual should be considered a permanent part of the snowmobile and must remain with the snow-
mobile at the time of resale. If the snowmobile changes ownership more than once, contact Arctic Cat Inc., Service
Department, P.O. Box 810, Thief River Falls, MN 56701, for proper registration information.
Every Arctic Cat Snowmobile meets or exceeds the standards of the Snowmobile Safety and Certification Commit-
tee and displays the SSCC decal. Arctic Cat endorses and encourages the safe use of all snowmobiles. Always wear
a helmet and eye protection. Drive with caution, observe all state and local regulations, and respect the rights of
others. ISMA members like Arctic Cat do their part to improve trails, sponsor events, and generally support the
sport of snowmobiling. As a member of the National Snowmobile Foundation, Arctic Cat Inc. promotes snowmo-
biling through education, charity, and research programs.

! WARNING
This snowmobile is a very high performance snowmo-
bile. Because it does accelerate rapidly and is capable
of very high speeds, it should not be operated by a
novice or an inexperienced operator. Never accelerate
rapidly or drive at high speed beyond the limits of visi-
bility or without being totally familiar with the terrain
and what lies in front of you. Obey speed limits and
never operate at speeds that do not allow adequate
maneuvering and stopping distances. Read and study
the entire Operator’s Manual and Safety Handbook.
Failure to follow this warning could result in personal
injury to yourself or others.

When in need of replacement parts, oil, or accesso-
ries for your Arctic Cat Snowmobile, be sure to only
use GENUINE ARCTIC CAT PARTS, OIL, AND
ACCESSORIES. Only genuine Arctic Cat parts, oil,
and accessories are engineered to meet the standards
and requirements of your Arctic Cat Snowmobile.
For a complete list of accessories, refer to the current
Arctic Cat Accessory Catalog.
To aid in service and maintenance procedures on this
snowmobile, an Illustrated Parts Manual is available
through your local Arctic Cat Snowmobile dealer.

Crankshaft Runout/
Repair Specifications
For those who have crankshaft work sent out to another shop, it is advisable to provide them with this information.
To use the specifications, first refer to the drawing; then find the letter which indicates the specification and refer to
the chart below the illustration. Be sure to note the proper engine column. Specifications are called out in both mil-
limeters and inches.
NOTE: We have given the proper location for checking crankshaft runout as the very edge of the straight
portion of the shaft where the oil seal makes contact. From the illustration, note that Arctic Cat has called
out three check points: at either end, out on the taper as shown, and also on the center bearing race. The
crankshaft is still supported on the outer bearings using V blocks. The maximum runout shouldn’t exceed
0.05 mm (0.002 in.).
728-144A
NOTE: Measure in from the shaft end the specified amount when checking runout at points D and F.
When checking runout in the center, place indicator on center of bearing as shown at point E. Maximum
runout at any of the 3 measuring points is ±0.05 mm (0.002 in.).

Selection Chart
Below is a list of rear suspension springs and specifi-
cations. This chart was compiled to assist technicians
in fine-tuning the Arctic Cat rear suspension when the
original springs are not optimum for the conditions
and a softer or firmer ride is desired.
A longer spring in areas (D) and (E) can be selected if
cut off to match the original spring. The replacement
spring must match the original spring in areas (C), (D),
and (E).

NOTE: The wire diameter and length of the spring
have a large influence over the valving of the
