MAINTENANCE

Lights

NOTICE: Avoid touching 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 fin-

gers do touch the bulb, clean it with an alcohol-moistened towel.

Removing Halogen Bulbs

1. Pinch the ends of the spring (1) 

together and lift until it releases 

from the spring retainer.

2. Lift spring carefully around 

wire harness (2) and flip to out-

side of housing.

3. With the wire harness attached 

to the bulb (3), withdraw bulb 

from housing.

4. Grasp bulb by metal base and 

carefully separate bulb from 

harness.

Installing Halogen Bulbs

1. Hold bulb by metal base and install into wire harness.
2. Insert bulb into housing.
3. Carefully flip spring back into housing placing it around wire har-

ness.

4. Squeeze spring together until it is over the spring retainer and 

release.

5. Verify headlight aim.

MAINTENANCE

Clutch System

Periodically inspect the clutch sheaves for damage, wear, or belt resi-

due. To maintain optimum performance, clean with non-oil based clean-

ers such as isopropyl alcohol.

NOTICE: 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 mainte-

nance and repairs must be performed by an authorized Polaris dealer. 

Any unauthorized modifications to clutches, such as adding or remov-

ing weights, will void the warranty.
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.

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.

Drive Belt Condition

Belt width and length must match the center distance of the clutches and 

sheave width of the drive clutch. For this reason, Polaris recommends 

that only O.E.M. belts be used. Other belts may match the dimensions, 

but can drastically change the shift pattern, resulting in poor perfor-

mance. See Belt Troubleshooting on page 111.
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.

Tip: A worn belt will continue to function, but will not deliver maximum perfor-

mance. Always carry a spare belt in case of an emergency.

For improved drive-away during extremely cold temperatures, remove 

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

snowmobile.

Drive Belt Removal

1. Stop the engine after operating in a forward motion.

NOTICE: Do not attempt to remove the drive belt after operating in reverse. The 

snowmobile must be stopped after forward motion to prevent damage 

to components during belt removal. 

2. Turn the ignition key off. Wait for 

the engine to stop completely.

3. Lock the parking brake (if 

equipped).

4. Open the hood.
5. Remove the clutch guard retain-

ing pin and open the clutch 

guard.

6. Rotate the driven clutch counter-

clockwise 1/4 turn by hand to 

ensure forward engagement 

before attempting to remove the 

belt.

7. Locate the L-wrench in the tool kit and install it into the open 

threaded hole in the outer sheave of the clutch. Rotate the wrench 

until the sheaves open far enough to remove the belt.

8. Firmly grasp the belt midway between the clutches and pull upward 

and rearward to remove. See illustration.
