to remove the chain and sprockets; then remove
the chain and sprockets. Remove chain lube oil.
Discard both nuts and washers securing the
sprockets.
7. Remove the three nuts securing the right side of
the track drive; then remove the O-ring seal and
bearing. Discard nuts and O-ring seal.

secure the right side with the bearing, new O-ring
seal, and new nuts. Tighten to 15 ft-lb.
2. Install existing chain and sprockets and secure
with new washers and nuts. Tighten to 50 ft-lb.
3. Tighten chain tensioner; then install chain lube.
4. Install chain case cover using existing six cap
screws. Tighten to 15 ft-lb.
5. Place the slide rail assembly into position and
secure with existing cap screws. Tighten to 34 ft-lb.
6. Secure the left side of the track drive using three

7. Install the resonator, side panels, and hood.
HYDRAULIC BRAKE
Arctic Cat recommends that the brake system (brake
lever, reservoir, hose, caliper, pads, and brake disc) be
checked daily for fluid leakage, wear, or damage and
for proper operation. Also, the brake fluid level must
be checked every time before starting the engine. The
brake fluid must be maintained at a level just below
the high mark on the reservoir.

DO NOT operate the snowmobile when the brake lever
lock is engaged or when any component in the brake
system is damaged, worn, or adjusted improperly. If
the snowmobile is operated and the brake system is
not functioning properly, severe personal injury could
result.
BRAKE FLUID
Checking/Adding Brake Fluid
1. With the reservoir in a level position, check the
fluid level in the reservoir. The brake fluid level
must be just below the high mark.

2. If the brake fluid level is below the low mark,
remove the reservoir cover and add Arctic Cat
approved brake fluid until the fluid level is just
below the high mark. Install and secure the reser-
voir cover. Do not allow moisture to contaminate
the brake system.
Brake fluid is highly corrosive. Do not spill brake fluid
on any surface of the snowmobile.
Do not overfill the reservoir. Overfilling the reservoir
may cause the brake system to hydraulically lock. Use
only Arctic Cat approved brake fluid. Never substitute
or mix different types or grades of brake fluid. Brake
loss can result. Brake loss can result in severe injury
or even death.
Changing Brake Fluid
The brake fluid must be changed on a regular basis and
whenever the brake fluid has been overheated or con-
taminated. The brake fluid should be changed every
1000 miles or at the end of the snowmobiling season,
whichever occurs first.
CHECKING BRAKE LEVER TRAVEL
Before each use, check the brake lever travel using the
following procedure:
1. Compress the brake lever fully.
NOTE: Do not pump the brake lever as it will pro-
duce an inaccurate reading.
