Track Lubrication

WARNING! Operating with insufficient lubrication between the rail slide and 

track guide clips can cause track failure, loss of vehicle control and loss of 

braking ability, which can result in serious injury or death. Avoid operating for 

extended periods on ice and other surfaces that have little or no snow for 

lubrication.

The slide rail requires adequate snow cover for sufficient lubrication. 

Excessive wear indicates insufficient lubrication. A new rail slide can 

cause faster heat build-up in limited lubrication, resulting in excessive 

wear.

Tip: If excessive rail slide wear occurs due to poor snow conditions, additional 

wheel kits are available. See your dealer for more information.

Tip: Track damage or failure caused by operation on ice or under other poor 

lubrication conditions will void the track warranty.

MAINTENANCE

Track

Moving parts can cut and crush body parts. When performing the checks and 

adjustments recommended on the following pages, stay clear of all moving 

parts. Never perform track measurement or adjustments with the engine run-
ning.

Track Tension

Track adjustment is critical for proper handling. Always maintain cor-

rect tension and alignment. Tension adjustments should be made only 

after the track is warmed up and limber.

WARNING! Improper track tension can cause serious damage to the 

snowmobile, which can result in loss of vehicle control and serious injury or 

death. Always maintain the track tension as specified.

1. Turn the engine off.
2. Lift the rear of the machine and safely support it off the ground.
3. Place the recommended weight or downward pressure on the track 

at the distance specified (see chart) ahead of the center of the rear 

idler wheel.

4. Measure at the point where the weight is hanging.

5. Check for specified slack between the wear surface of the track clip 

and the plastic rail slide.

ment on the other side 

of the track.

Tip: Check more frequently 

when machine is new.

10. Start the engine and 

slowly rotate the track 

at least five revolutions. Let the track come to a stop (do not apply 

brakes).

11. Check track alignment (see page 96) and adjust as necessary.
12. Tighten the locknuts.

Track Alignment

Periodically check that the track is 

centered and running evenly on the 

slide rails. Misalignment will cause 

excessive wear to the track and slide 

rail.
1. Safely support the rear of the 

machine with the track off the 

ground.

2. Start the engine and apply a 

small amount of throttle until 

the track turns slowly at least 

five complete revolutions. Stop 

the engine and let the track 

come to a stop (do not apply 

brakes).

3. Inspect track alignment by looking through the track window to 

make sure the rails are evenly spaced on each side. If the track runs 

to the left, loosen the left locknut and tighten the left adjusting bolt. 

If the track runs to the right, loosen the right locknut and tighten the 

right adjusting bolt.

4. After adjustments are complete, tighten locknuts and torque idler 

shaft bolts to 35 ft. lbs. (47.5 Nm).

5. Repeat steps 2 and 3 to verify proper alignment.
