BRAKE SYSTEM

Checking Brake Fluid
1. With the brake fluid reservoir in a level position,
check the fluid level. 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 reservoir cover. Do not allow
moisture to contaminate the brake system.
CAUTION
Brake fluid is highly corrosive. Do not spill brake fluid
on any surface of the snowmobile.
! WARNING
Do not overfill the brake fluid reservoir. Overfilling the
reservoir may cause the brake system to hydraulically
lock. Use only Arctic Cat approved brake fluid.
Checking Brake Lever Operation
1. Test the operation of the hydraulic brake system
by compressing the brake lever.
2. The brake lever must feel firm when compressed.

DRIVE BELT

Installing Belt
1. Set the brake lever lock; then remove the hood and
the left-side access panel.
2. Using Drive Belt Deflection Tool (p/n 0644-424),
thread the tool clockwise into the driven clutch
until the movable sheave opens far enough to
install the drive belt.
3. Place the belt (so the part number can be read)
between the sheaves of the drive clutch.
4. With the sheaves fully apart, roll the belt over the
stationary sheave.
5. With the drive belt properly positioned in the drive
clutch and driven clutch, turn the belt tool counter-
clockwise, release the brake lever lock, and roll
the belt back and forth to allow the driven clutch
sheaves to fully close.
6. After the belt is installed properly, install the hood
and left-side access panel.
Never operate the snowmobile without the belt guard
secured in place.
Checking/Adjusting Deflection
Drive belt length, condition, and deflection are all
important for peak performance. To check and adjust
drive belt deflection, use the following procedure.
1. With the engine off; remove the hood and left-side
access panel.
2. Make sure the drive belt is sitting at the top of the
driven clutch sheaves.
3. Place a straightedge on the top of the drive belt.
The straightedge should reach from the drive
clutch to the top of the driven clutch.
4. Using a stiff ruler centered between the drive
clutch and driven clutch, push down on the drive
belt just enough to remove all slack and note the
amount of deflection. The deflection should be
approximately 15.9-22.2 mm (5/8-7/8 in.).
NOTE: The amount of deflection should be exper-
imented with or tested to obtain best start-line per-
formance.
NOTE: Push down on the belt with the ruler only
until the bottom of the belt flexes upward; then
read the amount of deflection.
5. To correct drive belt deflection, loosen the jam nut
on the belt width adjuster on the stationary sheave.
6. Using an Allen wrench, adjust the set screw as
needed.
NOTE: Turning the set screw clockwise increases
distance between the sheaves (increases belt
deflection measurement); turning the set screw
counterclockwise decreases distance between the
sheaves (decreases belt deflection measurement).

HANDLEBAR ALIGNMENT

Checking/Adjusting
1. Verify that the drag link is centered.
743-067B
2. From the riding position on the snowmobile,
check that the handlebar is in a straight-forward
direction for driving.
NOTE: If the handlebar is in a satisfactory
straight-forward direction, no adjustment is neces-
sary. If not, proceed to step 3.
3. Loosen the two cap screws securing the steering
post bearing housing to the steering support
bracket.
