MAINTENANCE

Brakes

Bleeding the Hydraulic Brake System

Air in the hydraulic brake system will cause spongy brake lever action. 

Bleed the system before operating the snowmobile.

During the bleeding procedure, keep the brake handle as level as possi-

ble. The reservoir must be in this position to minimize the possibility of 

air entering the system through the reservoir vent.

1. Remove the brake master cylinder reservoir cover and gasket.
2. Fill the master cylinder reservoir to between the MIN and MAX 

marks or 1/4-5/16I (.6-.8 cm) below the lip of the reservoir open-

ing. Reinstall the gasket and cover.

3. Slip a rubber tube over the ball of the bleeder valve and direct the 

flow of fluid into an approved container.

4. Squeeze the brake lever a full stroke. Then unscrew the bleeder 

valve 3/4 of a turn to release air.

5. Close the bleeder valve and release the brake lever.
6. Repeat steps 4 and 5 until fluid flows from the bleeder valve in a 

solid stream free of air bubbles.

7. After bleeding is complete, refill the reservoir to the proper level. 

See page 87. 

8. Reinstall the gasket and cover.

WARNING

Operating the vehicle with a spongy brake lever can result in loss of brakes, 

which could cause an accident and lead to serious injury or death. Never 

operate the vehicle with a spongy-feeling brake lever.

WARNING

Overfilling the master cylinder leaves no room for fluid expansion and may 

cause the brakes to lock, resulting in serious injury or death. Always add 

brake fluid to the fill line as recommended.

Headlight Adjustment

The headlight may be adjusted for vertical aim using the following pro-

cedure.

1. Place the snowmobile on a level surface with the headlight approxi-

mately 25 feet (7.6 m) from a wall.

2. Measure the distance from the floor to the center of the headlight 

and make a mark on the wall.

3. Start the engine and turn the headlight switch to high beam.
4. Observe the headlight aim. The most intense part of the headlight 

beam should be aimed 2I (5.1 cm) below the mark placed on the 

wall.

NOTE: Rider weight must be included on the seat.

5. Turn the adjustment nut (+), located inside the hood, just below the 

headlamp opening. Turn the knob in or out as needed for proper 

aim.

MAINTENANCE

Lights

NOTE: Do not touch a halogen bulb with bare fingers. Oil from skin 

leaves a residue, causing a hot spot that will shorten the life of 

the lamp. If fingers do touch the bulb, clean it with an alcohol-

moistened towel.

Headlight Bulb Replacement

1. Pinch the ends of the spring (1) 

together and lift until it releases 

from the spring retainer.

2. Lift the spring carefully around 

the wire harness (2) and flip it to 

the outside of the housing.

3. With the wire harness attached 

to the bulb (3), withdraw the 

bulb from the housing.

4. Grasp the bulb by its metal base 

and carefully separate the bulb from the harness.

5. Hold the new bulb by its metal base and install it into the wire har-

ness.

6. Insert the bulb into the housing. Carefully flip the spring back into 

the housing, placing it around the wire harness.

7. Squeeze the spring together until it's over the spring retainer and 

release.

8. Verify headlight aim. See page 89.

Taillight/Brakelight Replacement

1. Remove the screws (1) securing the 

taillight housing (2).

2. Remove and replace the bulb (3).
3. Reassemble all components.

MAINTENANCE

Clutch System

Periodically inspect clutch sheaves for damage, wear or belt residue. To 

maintain optimum performance, clean with non-oil based cleaners such 

as isopropyl alcohol. 

Clutch Alignment Offset

Clutch alignment offset is important for maintaining optimum perfor-

mance. Please see your Polaris dealer if you experience a decrease in 

performance.

Clutch Center Distance

See your Owner's Manual Supplement for recommended center distance 

for your machine. If adjustment is necessary, see your dealer.

n

Drive Belt Condition

Periodically check the condition and tension of the drive belt, and 

always carry a spare. Inspect the belt for signs of excessive wear: frayed 

edges, missing cogs, cracks and excessive looseness. Replace the belt if 

any of these conditions exist. See Belt Troubleshooting on page 118.

For improved drive-away during extremely cold temperatures, remove 

the belt and warm it to room temperature. Reinstall it before starting the 

snowmobile.

WARNING

If you become aware of higher than normal clutch engagement or an unusual 

vibration or shift pattern, see your dealer immediately. Do not operate the 

machine until repairs have been made. 
All clutch maintenance and repairs must be performed by an authorized 

Polaris dealer. Any unauthorized modifications to clutches, such as adding or 

removing weights, will void the warranty.

CAUTION

The bushings in the weights and rollers of Polaris clutches are made of a 

material that may be damaged if lubricated. Do not lubricate clutch bushings.
